Cisco Modem + DLink Wireless + Warcraft III

[Khadgar]

First off, thanks for looking at this post. Here's my setup:
Cisco 678 DSL model/router - DLink DI-624 Wireless router - Multiple Computers (Wireless and Wired)

The problem is that I'm unable to host custom games on Battle.net with any of my computers connected wirelessly to the DLink (I dont know if I can do so wired). I can join games just fine, but cannot create/host my own.

Originally, I had the Cisco connected to the WAN port of the DLink. However, I decided that would probably make this setup difficult due to redundant DHCP servers, firewalls, NAT, etc. So, I hooked the Cisco into a LAN port of the DLink, set the DLink to IP 10.0.0.100, and disabled DHCP on the Dlink. So now, the DLink *should* just be a switch (in my understanding).

However, I still cannot host a Warcraft III game on Battle.net. I know I need to be able to access ports 6112-6119 to do this, so I'm guessing something is blocked somewhere. Do I need to do configuration at the Cisco end (this is not easy for me due to the text interface), the DLink end, or both? What settings do I need to change?

Thanks in advance!

With your current setup (Cisco routing/natting and DLink only switching/AP mode) you need to setup port forwarding in the router.

Thanks for the quick reply. By that do you mean setting the Cisco to port forward ports 6112-6119 to my Dlink (IP 10.0.0.100) or forward them to my PC?

I tried forwarding the ports to my wireless PC (10.0.0.2) from the Cisco and was able to host a game. However, once the game started after everyone joined, they were all kicked from the game. It seems like I made some progress because I couldn't even get people to join the game before...

Here are the commands I added into my Cisco to make it work this far:
set nat entry add 10.0.0.2 6112-6119 0.0.0.0 6112-6119 udp
set nat entry add 10.0.0.2 6112-6119 0.0.0.0 6112-6119 tcp

I don't even know if this is entirely right, but I followed a guide I found online to get these commands (http://www.u.arizona.edu/~trw/games/example.htm). Am I missing something else? Did I do something wrong? Thanks

I decided to look at my DLink's logs and there is a posting in there every 3-4 seconds saying either "DHCP Discover" or "DHCP Discover no response". Does anyone know where this problem may be coming from? Could it be causing my disconnects when hosting?
