To anyone with knowledge about LANs, NATs, and port forwarding around a router.
I am on an iMac OS 9.1 on a small home LAN (3 macs) connected by a simple hub to a Cisco 675 router which is connected to ADSL (640 Kb/s Qwest)
I see from other postings that it is not always trivial to play host for an online game if you have DSL and are on a LAN. Apparently requests from other players to join your game must be directed by the game server through a specific game port in the router to your location in the LAN by a little thingy called NAT (though why I don't need NATs help to direct my web traffic to my little box I have no idea). I have been wrestling with this problem off and on for about 2 months now and am getting nowhere. I hope someone in the forum can help me out.
A post in Help from Gameranger (the Mac gameserver in this case though I don't think this problem is unique to Macintosh in anyway) said, after trying to explain about port forwarding and NAT, to enter the local address of the router "into your browser"! The local address for the router is 10.0.0.1 but I have no idea where to enter such an address into a browser (They don't answer e-mail requests for clarification). I tried the proxy box in IE and all it did was lock up my computer. Anyone have any suggestions on this fix??
I tried to learn a little about my router, NAT, and port forwarding. If I have it right, NAT permits the router to determine which box on a LAN incoming requests should be routed to. My computer has the local LAN address of 10.0.0.4. the router's local address is 10.0.0.1.
The following excerpt from a tech post about the Cisco 765 .

How does one set up port forwarding on the Cisco 675 router?
Article ID: 94
Updated: Aug-07-2002
The command to set up port forwarding on the Cisco 675 is:
set nat entry add <internal ip of server> <port number> <protocol>
For example to set up a mail server whose LAN address is 192.168.0.2:
set nat entry add 192.168.0.2 25 tcp
They seemed to be trying to do the same thing for the mail server that I want with my imac. I entered two commands to the router
"set nat entry add 10.0.0.4 23978 tcp" and an identical one for udp.
they both seemed to take. But I still couldn't host. (23978 is the port given for that game)
Entering the local address of the router (10.0.0.1) in the command line also didn't seem to work.
If anyone knows about this stuff or knows what I am doing wrong I would really appreciate a response.
