Need a router that allows changing off ttl

Title mostly sums it up.

I work over in Afghanistan where there is only one ISP available. Needless to say the service is pretty sub par, and they are incredibly restricitve about what they "let" us do with the interent (we pay for). I'm trying to hook up a wireless router to it in order to not have my laptop tethered to the ethernet cable and use my iPad.

When I hook up a router I am able to get to the login page, but that's it (never able to authenticate). I know that this is due to the ISP setting the ttl to 1. I know this becuase I dealt with the same ISP in Iraq, but I had a router that allowed me to change that setting (it was a d-link, not sure of the model number), which my wife gave to her mother hence me needing another.

I'm just looking for a router that will allow me to change the ttl with the factory software right out of the box. I'm not smart enough to use tomatoe or DWRT (or whatever it is lol). I bought another d-link thinking the software would be the same. That wasn't the case. I've googled and searched the internet, but haven't been able to get much of answer.

Thanks.

    while connected to ur router, type in 192.168.1.1 in a browser and tinker with the settings there. That will probably fix it.

    Your best bet is DDWRT/OpenWRT/Tomato (with a compatible router) I'm afraid, and use one of the many walk-throughs on the internet.

    With Tomato, there is a setting called "TTL Adjust" in the advanced menu:

    With DDWRT/OpenWRT (or linux box), you have to enter an iptables command
    http://www.dd-wrt.com/wiki/index.php/Iptables
    (Scroll down and there is a section for "Modifying the TTL" which shows examples of exactly what to type)
    OpenWRT needs an additional step I believe:
    https://forum.openwrt.org/viewtopic.php?id=12829

    Tomato looks the easiest, OpenWRT the most difficult, but possible with all 3.

    The "next" best answer is to plug it directly into a linux box, and set it up as a router - which can be done as a virtual machine on a PC, but eats more resources if your gonna do something else with that PC. That's gonna be essentially the same thing as DDWRT/Tomato, only running on a PC instead of on router hardware.

    As far as consumer level routers, I can't say that I know of any off the top of my head. Your best bet may be to call the ISP and see what they recommend.

    I've messed with all the other settings I need (port forwarding, etc), but I know for a fact that it's them setting the ttl to 1 that is killing it.

    I appreciate the info, but I'm worried that's a little above my head. If ic an't find any (out of the box ones) that work, I'll guess I'll give Tomatoe a try.

    I don't know if you can get this out in the field, but there are some routers that come with DD-WRT pre-installed:

    Thanks for the tip man. I went ahead and ordered it (they did ship to APOs).
