Router Problems... BIGTIME! :(

Chief

Lo laeds,
The company im working for run a wan between their offices in Donegal and Dublin via a 64k leased line. At each end we have a Motorola Vanguard 320 Router and until recently all hasnt been to bad. But in the last few weeks weve had to do a network overhaul both here and in dublin, changing all ip's to standard 192.168.*.*'s. Basically here is now the 192.168.0.* range and Dublin is the 192.168.1.* range. We changed the routers address at each site to 192.168.0.1 & 192.168.1.1 respectively. Problem is we cant get access to the Dublin network and the Dublin network cant get access to us. I can ping my router here, and Dublin can ping their router, but we have no way of accessing each others routers... nothing works.. not ping.. not traceroute not anything. We have tried just about everything we can think of and I was wondering if anyone could help shed a little light on things...

Thanks a million in advance guys.

I'm going to go out on a limb and mention gateway settings......?

Have setup routing tables on each of the routers?

After you've done that, try and ping the Dublin network from the Donegal router and vice versa. Every PC on the Dublin network will have to set their default gateway to 192.168.1.1 and Donegal 192.168.0.1 (unless you got a more complex setup in either of the sites).

If you have any more problems.... (I presume you haven't been fired yet )

Eh, you will actually need to create a tunnel between the two routers...

You create a tunnel because routers on the net, as soon as they see a private IP address they just drop it. a 192.168.*.* address won't work on the internet essentially.


What you have to do is as i say above create a tunnel. I'm not familiar with the motorola's. Do they have config files ? Do you have copies of the original settings ? You should be able to look at the old settings and see how they were setup originally with the old IP's.

The old tunnel is probably still setup, just to work with your original IP's. You will need to change the ip in the actual tunnel configuration, which may not be the same as the local ethernet connection ip.

Hum.. hope that's been a bit of help. Post up more info on what you have actually done so far to the router.

He never mentioned the Internet. BTW that's what NAT is for.

add a route between to two?
default gateway( as mentioned above)?

Chief

Lads, cheers for taking the time out to help!
It was a combination of port settings on the router itself and then setting up default gateways to the correct addresses, again thnx a million for the help

NAT is as secure as you make it, if you use a proper firewall to do the NAT then it should be rock solid. (Doing NAT on an Internet router isn't secure though)

BTW what's a "WAN over the Internet"? You mean VPN?

Good point ! Didn't notice that.

Aye, I'm aware of NAT. However in a WAN over the internet scenario, NAT is not an ideal solution, being insecure. But as you say, there is no mention of internet in his above post, so all the other posts of setting up routing are probably correct !
