Do you require a physical router to enable mac address filtering?

    Hi guys,
    I have a plugin USB type 3 connect modem which is wifi enabled.I was wondering if it is thus not possible to increase security via mac address filtering minus a physical router?

    A MAC filter is like a 1 ft around you garden, it's not going to stop anybody breaking into your house but may stop the old and polite from just walking in.

    Are you sure your USB dongle does wireless { 802.11x } since every 3G { Vodafone / 02 / Meteor } unit I have seen are all made by the same people and only do 3G/CDMA/GPRS.

    yeah it definitely does wifi it's an Huawei E5830,oh it did not realise MAC address filtering gave such limited protection.I was under the impression it gave greater security over a larger area?

    Ah, it's a MiFi.

    I know you can do advanced settings on it but only via a hidden menu.

    Try googling the model number and "hidden menu".

    MAC filtering doesnt hurt for sure..... (Anything to stop someone from gaining access is a plus :))

    Enabling WPA2 { AES } and just a line from a song or the fist line of your address as the passphase would be better.

    If all you have enabled is MAC address filtering (and no encryption enabled), then all a would-be attacker has to do is monitor the channel, see what MAC addresses are allowed in, then change their MAC address to match.

    WPA is just as easy to set up (if not easier -- no copying of awkward 48-bit numbers), and is much more secure. Once you've done that, there's no real need to bother with MAC filtering - if somebody is able to figure out how to bypass WPA, they can pretty much do what they want anyway, and it means you don't have to bother reconfiguring your setup anytime you get a new device, or want to let a friend hook their laptop in etc.

    A MAC (Media-Access-Control) address is used so that packets within a local network can be sent to the correct node. The concept of a MAC address wouldn't be applicable here. If anything, the equivalent on the E180 would be either the IMEI number or the mobile number. It is (often) illegal to change the IMEI number on a cellular device, and the mobile number can be changed by changing the SIM card.

    no, it's given by the ISP

    you could use something like dydns.org to map back to your current address

    It would help if we knew what exactly you were trying to do? ('regulate my ip address' sounds like a means to an end, -- what's the end-game you're looking for?)

    simply make my ip more static i have hosting which require me to add my ip adress to the list on firewall so if i want to use it on dongle i would have to add new address everytime i get on online ... so i would like to swap maybe between few addresses i would know (in case the other address would be taken by some1 else)

    You'd need to contact your ISP about providing you with a fixed IP (they're unlikely to do this unless you are a business customer), or else your hosting provider to see if they've alternate ways to connect in (e.g. using an SSH tunnel rather than relying on an IP firewall).
    An alternative solution would be to find a different hosting provider (most of them don't have this requirement for the very reason that a lot of people who need hosting solutions connect in with dynamic IPs).

    ok thanx for these . i could always get myself a ssh and set up with proxy but that would be quite annoying im trying to avoid that and im pretty sure there's some way to go around it.

    There are a finite number of IPV4 addresses
    anything over 240. is reserved
    a large number of these are owned by the early adopters of the internet, like UK social welfare , Apple . HP , US government,

    so really only half the addresses are available for ISP's and there arent enough to go around

    hence if you want a static address you either have to pay an additional cost for it
    or you have to setup some way of advertising your existing address

    or when Irish ISP's get around to it there is the option of an IPv6 address

    thanx but thats not related to my question know that the network can have like 1000adresses then ip addresses are more than less given by dhcp(lan network) - dhcp is giving out ip based on the mac address (you change mac you change ip)since this question is related to PPP type of network which seems not to depend on mac address im wondering how to customize ip address (change it on demand to the one i had previously...)
