Router/modem port forwarding help...

[deathparade]

I have a modem where the telephone line comes in and spreads it out to house phone and the router.

The router serves a bunch of Pc's wireless and 2 over a cable.

 

I can port forward in the router itself but whenever i try open a port in the modem TO the router the modem just craps out and has to be reset to regain internet..

 

Should i get a new modem or is there a way around this?

 

I wanna run a Team Fortress Classic server again ._.

Fumbling my buttons today, didn't mean to 'thank' you, that would have been stupid of me.

 

You haven't really given enough information nor told us what you are trying to do, but it sounds like your router is working correctly. You turn on a DMZ with no exceptions so you get no inside-outside comms.

 

If you don't know what you are trying to accomplish, just leave the DMZ turned off. If you don't have anything (like a webserver) to place in one, you don't need it.

Problem is it doesn't really have a DMZ option let me edit this crap...

 

It btw used to work before

[Symon]

If it used to work and it were mine, I'd record all the relevant settings, check I knew the default password and try a hardware reset. Then restore my 'known' working config and hope.

 

If that failed, I'd consider getting another one.

On mine is listed as Virtual servers.

 

But it depends on your router model.

it's being reset so much (our internet is kinda unstable because laying a new line in this area wouldn't make much profit for the ISP's)

See if the router supports tomato or dd-wrt that'll let you get a proper DMZ up and running without much of a hassle.

it's a Thomson TG712 NOT a Router (which is where those firmware's are apparently for)

[Mashi]

Well, if you've got the money, I'd recommend picking up a asus RT-N12 they're pretty good. Though I'm still using a wrt54gl

Why do you keep sending stuff about Routers? it's a modem! routers can't do anythin with a phone my router works fine cause it's like 3 months old...

[Mashi]

Short answer? In 70-80% of all cases, when a modem craps out on a "open port to" it's the router doing it, because it's getting a bad RFC command. Modem's usually play nicely and properly adhere to the RFC standards, routers not so much. I'll let you figure it out on your own. Just because something is new, doesn't mean it works properly.

Well it started with our old router which later burned out because in the summer it gets really hot in the loft! (i have no idea if that word is right YAY Google translate) and we got a new one... The Modem is just so shit that it blows out even if you are doing nothing!
