Hello all.
I have a Cisco 1605r connected to a cable modem to share my internet connection. I am trying to play a flight sim that requires me to forward 2 udp ports (2934 and 2935) to the PC that I am playing the game on. I tried to add what I thought was the right configuration change but, its still not working. If any of you could review my config and the output from "sh ip nat translations" to help me fix this, I would really appreciate it.
Thank You, Chris
Here we go...
1605r#sh run

And here is the output from

and
sh ip nat translations | inc 2934
x.x.x.x is my dhcp assigned address from my isp:
udp x.x.x.x:2935 192.168.1.101:2935 --- ---
udp x.x.x.x:2934 192.168.1.101:2934 65.49.176.170:1157 65.49.176.170:1157
udp x.x.x.x:2934 192.168.1.101:2934 --- ---
Does everything look ok on my end?
Thanks for any help in advance! :)

I think you are missing extendable keyword after ip nat inside source static command.Please try it.
ip nat inside source static udp 192.168.1.101 2935 interface Ethernet0 2935 extendable
ip nat inside source static udp 192.168.1.101 2934 interface Ethernet0 2934 extendable
ip nat inside source static tcp 192.168.1.101 3724 interface Ethernet0 3724 extendable
ip nat inside source static tcp 192.168.1.101 6112 interface Ethernet0 6112 extendable
ip nat inside source static tcp 192.168.1.101 6881 interface Ethernet0 6881 extendable
Bcos you are mapping different port to same inside ip addresses.
If it works let me know
Thanks & Regards

I tried to modify the line but it told me that invalid input was detected.
Maybe my IOS is to old?
Cisco Internetwork Operating System Software

Thank You, Chris

It appears to be working now. Thanks for you help. I guess it was a server side issue or a non network problem I was having :)
