Network Play (internet) - ADSL Gateway Modems

[Bob R]

Hi All,

My brother and I in Ireland have been playing tacops pbem mode and having much fun and thought. Tonight, we thought we'd try network mode. We followed major H's instructions for host and joiner to the letter. We turned off the software firewalls and set up the adsl modem/gateways to allow TCP (instead of UDP) via port 7023 (tacops port) and set the address for that to our internal pc address 198.xxx.xx etc. Then we ascertained our internet IP for the host player and the host could "ping" fine (with either of use hosting - we tried it both ways). The joiner could, however, never find the host! Any ideas here on finding each other via adsl modem/gateway?

Thank you for any help. I am about to give up on playing on network via adsl. Our son tried to host it (demo game, which we still retain for testing) using the settings he uses for Battlefield 1942, but it didn't work for tacops. The host can ping fine - no error, but in all cases the joiner cannot find the host.

> 198.xxx.xx etc

I am not sure what the statement above indicates. An address starting with 198 would be a LAN address AND should only be used if both players are on the same LAN.

The address that the joiner must use in an Internet game is the host's Internet IP address and not his internal/LAN PC address. How did you determin your Internet addresses? When I need to find my Internet address I make a quick trip to www.ipchicken.com.

I am not familiar with the ins and outs of ADSL so perhaps one of the guys who use ADSL will chime in.

One of the problems with ADSL modems is that the IP number given to you by the program is that of the modem itself.

Not your pc's IP number.

You should change the settings in your modem manually.

I think that will solve your problem.

Hi Major,

I am aware of both my internal address (192 (not 198 - my error in my message).168.0.1 and my WAN (internet) IP of 168.103.108.211 . My understanding from our son, a software engineer, is that in the following modem instruction:

*************

Selecting Port Forwarding in the “Advanced Configuration” screen generates the

“Port Forwarding” screen. Port forwarding allows certain programs to bypass the

Gateway’s built-in firewall, allowing access to parts of the network (for hosting a

Web or ftp server, for example). To use port forwarding, enter the IP port range in

the “IP Port Range” text boxes. (If more than 10 ports are needed, Actiontec recommends

using DMZ Hosting. See “DMZ Hosting,” below, for more information.)

Choose the protocol type from the “Protocol” list box, then enter the IP address of

the computer on the network to be used as a host. Click Add. The forwarded ports

appear in the “List of Forwarded Ports” text box.

To remove forwarded ports, highlight them, then click Remove.

***********

... the address I should use - "ip address of the computer on the network" is the INTERNAL address of my pc (192.xx etc) and not the WAN/Internet IP address. Perhaps he is mistaken and I should use the WAN/Internet IP address.

I will try that next! Thanks for your reply.

Hi Stoffel. Thank you for your tip. I'll give you the same reply that I gave the Major:

I use a Lynsys router which also provides port forwarding as well as DMZ hosting.

I have never had any lasting succes at configuring its port forwarding features for any networking program - so I also seem to be missing the magic touch for networking .

Instead, I use its DMZ feature for the duration of any network game and then turn it off as soon as I am finished.

The 192.x.x.x are the designated local-only Class C addresses, not the 198.x.x.x

Here is a reliable way to find your IP address even if you are subject to a HTTP proxy (which disabled the normal HTTP-based services for figuring out your IP address):

Hi Red Wolf,

We finally found the combination! my brother left his software firewall on and then set the asdl up for NAT. The internet (WAN) IP addresses we had for each other were in fact accurate. Thanks for your tip.
