IChat File Transfer/Video Chat won't work... :(

Question

Hi Everyone,
I am trying to get ichat to allow file transfers/video chatting on my Mac, I have a feeling that the setup through the routers that we have are not allowing it to function as it is constantly giving me errors. My set up is a Cable Modem hooked into a Netgear WGR614 v6 and then an ethernet wire running from that router to a Linksys WRT54G v8. I have the WRT54G set up with the following settings:
IP: 192.168.1.136
Subnet: 255.255.255.0
Gateway 192.168.1.1
Static DNS 1 and 2: Are my IP's DNS servers
Static DNS 3 is blank
Local IP address is .199 with a subnet of 255.255.255.128
I have DHCP enabled starting at .200 with 30 users
My computer is also set up statically at port .233.
The Netgear WGR614 v6 is set up with the following settings:
Get IP/DNS dynamically from ISP
DHCP Range from 192.168.1.2 to 192.168.1.51. Router is on a subnet of 255.255.255.0 the linksys is set up statically to the Netgear
SO, this brings me to my issue, I am trying to get ichat file transfer/video to work, I have followed the instructions for setting up portforwarding from portforward.com for ichat on both the netgear and the linksys. On the linksys, i set the IP address to forward to as my computers (.233)
On the netgear, i set the ip address to forward to as 192.168.1.136 (the static IP of the linksys).
Anyway, I am hoping someone can point out what I am doing wrong as I am still getting this error: An AIM error has occurred. Unable to talk directly to your buddy. I am also getting this error: An AIM service error occurred. The server message was: Serv:RequestTimeout.
My OS X firewall is off.
THANK YOU SO MUCH FOR YOUR HELP IN ADVANCE!!

Hi,
I am not sure I have understood your Networking here.
You say the Netgear is getting an IP (Via DHCP) from the ISP.
You go onto say it is at 192.168.1.1
It issues IP addresses from 192.168.1.2 through 192.168.1.51 and the Linksys has an IP outside this range at 192.168.1.136
Your computer is at 192.168.1.233
As both devices are using the 192.168.1.xxx group and doing DHCP (even with restricted groups) how does the computer know which one to connect to ?
You should be able to change the group that each device is using for it's own network (I would suggest the Netgear)
You should also turn Off DHCP (to the LAN) in the Netgear so it's own network (subnet) only goes as far as the Linksys.
Similarly in the Linksys make sure DHCP is Off or change the Mac to use Manually (Static) with DHCP.
Both devices can do UPnP found in the Administration tab in the Linksys and the WAN page of the Netgear.
Turn Off/disable all Port Forwarding in both devices.
It may also pay to copy across the Linksys and Computer the DNS server IPs from the Netgear.
