Internet not working w/ Modem but works with Router???

[ConsoleElosnoc]

Hi everyone =),

Okay, this is not my problem.. this is my friend's problem (He lives in NY and I live in Vancouver) so I couldn't be physically there to see what's wrong...

By chance (or a miracle) I searched on google and ended up here =D!

Here's the problem:

My friend has a pretty decent computer/ High Speed Internet/ Cable Modem.. He used to be able to host CS(it's a game) Servers up until 2 nights ago when it suddenly crashed... We tried to fix it yesturday and nothing worked...(We tried almost everything.. like reboot system..checking everything is connected properly.. turning modem off and on... Network Troubleshooter)...

When he connects directly via the Cable Modem.. It says he has Local Area Connection... but he cant connect to the internet(Therefore cannot host the CS server)... His ISP also says that everything is working over at their end...

But.. if he connects to the router that connects to the cable Modem... He can use the Internet.. but Can't Host the CS Server cause it's a router connection....

I couldn't be physically over there to see the problems and such (since we are seperated by alot of kms?).. So posting to see if anyone know of this problem and how to fix?

Thanks,
CE

Sounds like any solution will require logging directly into either the modem or the router. Cable modems are usually proprietary and hard to get manuals for but the ISP will usually walk a person through most setups. I believe that the thing to do (especially because the router is usually needed for connection sharing) is open a hole in the routers firewall to allow requests to come in from specific locations. I've never done that (development machine must be sealed) and details are brand name specific, but once a person is inside the router (http://192.168.0.1/ or http://192.168.1.1/ - the former is for D-link) it may become clear and there are usually help pages, too.

The modem has probably had its DHCP or DNS service disabled somehow.
One thing that might work there is hold in the reset button for a really long time.

The thing is... before 2 days ago.. he could just use the cable modem to connect to the internet... host the CS server.. which only has the static IP...

Now with the router.. every time he creates a server.. the IP is dynamic so it comes out different every time (also sometimes you can't connect).. that's why we don't want the router to be involved for the server hosting...(and normally it just sits on the side unplugged)

We're trying to get his ISP tech to come in and give it a wack...but like all ISPs they like to put people on hold =/

How long do you suggest for the reset?

<snip>How long do you suggest for the reset?

Half a minute should do it. If you give relevant details, like brand, etc., we may be able to dig up extra info. Thanks.

Okay
ISP:
Optimum Online

Modem:
Motorolla SBV 5120

=)
I did some digging myself in optimum but the topics didn't really help..(probably cause it was at 12 in the morning and I started to get annoyed XD)

If that helps let me know =D

Well, VOIP may complicate things greatly (I have no experience with that). Looks like the manual is here.

I found the exact same thing on optimum..
