If you just plugged it in to another modem or router, it means you did not set it up right. Whatever port forward rules you add on this Mikrotik will mean nothing as you will be double Natting (routing to a new subnet twice). Consoles will find the ports they open are blocked by the modem. It will work, but it will only work for connections originating from inside your lan, any connections coming from the internet will be dropped by the gateway modem/router as it will not know what to do with them.

You need to bridge the modem and add PPPoE to the Mikrotik.

My eircom router/modem was in bridge mode when I connected it to the Mikrotik ether1. I reviewed the online guide for initial configuration and it did not mention PPPoE so I did not add it as things appeared to be working. I will look into adding PPPoE.

What about my query on caching?

PPPoE is the protocol being used to get your public IP on the Eircom modem, you need to add it on the Mikrotik so it gets your public IP, not the Eircom modem

Caching what? To cache web pages you'll need a pc and a lot of configuring and transparent redirecting, it's probably not worth the hassle. Enable the DNS cache to cache DNS requests so regular domains are not looked up each time, but returned from the router. Also, make sure the DHCP server is giving out the routers IP address as DNS in it's leases

Thanks again for you time and patience Smee, I really appreciate it!

Added PPPoE, was not sure about DNS Cache? When I checked IP->DNS it looked like caching was happening?

Also is there a test I can do to confirm double NAT is not happening?

Here's my current config from using 'export compact' does it look ok? Where should I look to improve things now?

That looks good, to test you don't have double Nat do "ip address print" and you should see a public ip address marked D (dynamic) assigned to the eircom-pppoe-out1 interface, (a public ip is one that doesn't start with 192.168.x.x). Also if you do a traceroute (tracert on windows) to www.boards.ie on your pc it will show you the hops. Be sure to disable wireless and pppoe on the Eircom modem.

The DNS cache is enabled and DHCP is giving out the router ip as DNS.

smee again · 13-10-2013 10:09AM

Handy that you posted your config, will work perfect for anyone with Eircom once they bridge their modem. Only thing they'd need to edit is the wireless SSID, security key, set their desired channel and set a router password

I think we are good?

Spotted a mistake, you have 192.168.88.1/24 applied to wlan1, it should be bridge-local (which is wlan1 and the lan ports 2-5)

Actually I think there was an error in that, incoming traffic was working but I could not connect to internet, seems I needed to disable the DHCP Client for ether1, now seems all good.

Should I now consider setting up UPnP?

Updated Config.

I have HP PSC 1510 All In One printer beside the Mikrotik which I normally connect to a laptop via USB cable to print. I am just wondering would plugging the printer USB into the USB slot on the Mikrotik allow me to then share the printer around the home network or is that not supported?

Let me know, thanks!

I forked out some serious money on a Asus Ac66u, but as I said I wish I had seen this thread first, but whats done is done.

I could do with a wifi repeater somwere on the landing to increase coverage upstairs..would it be overkill to buy one of these to use just as a repeater for my Asus?
And would it be difficult to config ?

I bought a second one of these purely as an access point (better than a repeater - because it has a wire to it). It was easy to get the wifi working. However my wired points on it aren't set up correctly yet.

Difficulty setting up VPN. I tried to follow the instructions in this thread but am failing.

Setup VPN pool

add name=VPN-POOL ranges=192.168.88.90-192.168.88.99

Add New User

/ppp secret
add name=New_USER password=password1 service=pptp

Turn on PPTP server

/interface pptp-server
add name=pptp-in1 user=""
/interface pptp-server server
set enabled=yes max-mru=1460 max-mtu=1460

Set profile to assign IP's from pool and add it to the bridge

...lost at this point - simply copying the code into the terminal doesn't work

Have you tried manually creating it in winbox using the commands as a guide? RouterOS has had many updates since that was posted, may be slightly different now

Sniipe · 16-10-2013 03:47PM

Hi Smee_again, I tried to do it manually using winbox, but I'm failing... I will try and do a quick youtube vid of my process and post it here (when I get a time between juggling 2 babies

) By the way thanks for your help so far.

Question: I have an RB1100 setup as my main router (main internet connections in here) and a RB951(insert random letters that dont make a lot of sense in here) as my Wifi box... I have managed to set the RB951* up as just an AP, but when doing so, i lost the ability to manage it using anything, including WinBox... Any ideas?

Also, as a related question, is 6.x stable enough to upgrade to now?

Question: I have an RB1100 setup as my main router (main internet connections in here) and a RB951(insert random letters that dont make a lot of sense in here) as my Wifi box... I have managed to set the RB951* up as just an AP, but when doing so, i lost the ability to manage it using anything, including WinBox... Any ideas?

Assign an IP address to the ethernet port or bridge interface so you can manage it. You will always be able to get in on layer 2 telnet (by mac address). Run Winbox and click the [...] button and it will find your routerboard by it's mac address, click on the mac address and you're in. This is handy to know if you ever lock yourself out of the router by applying an incorrect firewall rule, IP is layer 3, the network layer.

Also, as a related question, is 6.x stable enough to upgrade to now?

It's been stable for ages, wireless performance is miles better

Thanks for the tip, but that second method is not working... will try assign a static IP and see if that works... just have to reset the box again...

Cool... will chance upgrading the 951 first, then the 1100...

Try directly connected to a lan port, you'll need to assign a static ip and gateway, won't matter what they are

I added two firewall redirects to force all DNS requests on port 53 to the routers DNS cache. This is needed if you are using OpenDNS adult content filtering as setting a static DNS on the device to any public DNS is an easy way around the content filtering.

/ip firewall nat
add action=redirect chain=dstnat comment="redirect dns" dst-port=53 protocol=tcp to-ports=53
add action=redirect chain=dstnat dst-port=53 protocol=udp to-ports=53

Difficulty setting up VPN. I tried to follow the instructions in this thread but am failing.

Right, I just figured this so I'll share. There are a few things missing from what was posted earlier in the thread. My router is 192.168.80.1, change the subnet below to suit your own router

You need a pool of addresses and a single local address.
I used 192.168.80.90 as local and set the pool to 192.168.80.91-192.168.80.99 which is outside the DHCP pool and not used as static. I'm using the profile default-encryption, which may be already created but not set (this may be the difficulty you were having snipe). Set the DNS server as the routers IP

/ip pool
add name=VPN-Pool ranges=192.168.80.91-192.168.80.99
/ppp profile
add name="default-encryption" local-address=192.168.80.90 remote-address=VPN-Pool use-mpls=default use-compression=default use-vj-compression=default use-encryption=yes only-one=default change-tcp-mss=yes address-list="" dns-server=192.168.80.1

Next you enable the server and add the interface

/interface pptp-server server
set authentication=mschap1,mschap2 default-profile=default-encryption enabled=yes keepalive-timeout=30 max-mru=1460 max-mtu=1460 mrru=disabled
/interface pptp-server
add disabled=no name=pptp-vpn-server user=""

Then all that you need to do is create users

/ppp secret
add caller-id="" disabled=no limit-bytes-in=0 limit-bytes-out=0 name=vpnuser1 password=vpnpass1 profile=default-encryption routes="" service=pptp
add caller-id="" disabled=no limit-bytes-in=0 limit-bytes-out=0 name=vpnuser2 password=vpnpass2 profile=default-encryption routes="" service=pptp
add caller-id="" disabled=no limit-bytes-in=0 limit-bytes-out=0 name=vpnuser3 password=vpnpass3 profile=default-encryption routes="" service=pptp

I have HP PSC 1510 All In One printer beside the Mikrotik which I normally connect to a laptop via USB cable to print. I am just wondering would plugging the printer USB into the USB slot on the Mikrotik allow me to then share the printer around the home network or is that not supported?

Let me know, thanks!

Best Google that one

So I asked over on the MikroTik RouterOS forum and was told the RB951G-2HND does not support printers.

I was looking at the manual for my Zyxel Eircom F1000 and on page 181 it states you can connect a printer via its usb port for sharing over the network.

Given my Eircom router is now in bridge mode and I am using the RB951G-2HND as my main router is there any way I can take advantage of the Eircom USB printer sharing option still or?

Not if it's a bridge and being tunneled through (PPPoE is a layer 2 tunnel) it is not routable to on your network. That modem manual is very vague about print server, you sure it would work? Also, the disadvantage of setting a print server is that the scanner will not work unless directly connected to a pc.

Noticed this in my logs this morning.

From a google of the IP address looks like a spammer from China?

Anything I should do about it.

Yeah, it's just random spambots trying to login to your ssh server, you see this once you have ssh enabled on the router. I have a few rules added to my config which makes a nice honeypot to tackle this.

/ip firewall filter
add action=add-src-to-address-list address-list=trying_to_rdp address-list-timeout=1d chain=input comment="list IP's who try rdp" dst-port=3389 protocol=tcp
add action=add-src-to-address-list address-list=trying_to_login address-list-timeout=1d chain=input comment="list IP's who try remote login" dst-port=20-23 protocol=tcp
add action=drop chain=input comment="drop ssh brute forcers" dst-port=22 protocol=tcp src-address-list=ssh_blacklist
add action=add-src-to-address-list address-list=ssh_blacklist address-list-timeout=1w3d chain=input connection-state=new dst-port=22 protocol=tcp src-address-list=ssh_stage3
add action=add-src-to-address-list address-list=ssh_stage3 chain=input connection-state=new dst-port=22 protocol=tcp src-address-list=ssh_stage2
add action=add-src-to-address-list address-list=ssh_stage2 address-list-timeout=1m chain=input connection-state=new dst-port=22 protocol=tcp src-address-list=ssh_stage1
add action=add-src-to-address-list address-list=ssh_stage1 address-list-timeout=1m chain=input connection-state=new dst-port=22 protocol=tcp
add chain=input comment="allow ssh" dst-port=22 protocol=tcp

1st line logs IPs trying to remote desktop
2nd line logs IPs trying to login to the router over FTP, SSH or Telnet (ports 20-23)
The next few lines will prevent SSH brute force, the IP will be added to an address list on 3 stages and then added to an SSH blacklist and blocked for 10 days on the fourth failed attempt.
The last line is the rule that allows SSH

You will see the IP's build up in /ip firewall address-list. It's not my work, it's from here http://wiki.mikrotik.com/wiki/Bruteforce_login_prevention

Here is a full export of my firewall filters, there are some very important drop invalid, allow established connections and accept lan rules in there

Change the port the board uses for SSH to reduce the attempts a little bit
