Ports don't get forwarded properly

Hi, I've just bought a Cisco 887m-k9 and I am trying to forward the ports. I have a Polycom HDX H.323 device connected to it with a static IP of 10.10.10.5 (ethernet port 0). Previously I had a consumer grade Linksys router which worked fine (I simply entered ports into the GUI), but I couldn't hardcode LAN port speed so I bought this. I have the list of TCP and UDP ports which are forwarded using the following commands:

ip nat pool Polycom 10.10.10.5 10.10.10.5 netmask 255.255.255.0 type rotary

ip nat inside source static tcp 10.10.10.5 80 88.xxx.xxx.49 80 extendable

ip nat inside source static tcp 10.10.10.5 443 88.xxx.xxx.49 443 extendable

ip nat inside source static tcp 10.10.10.5 1300 88.xxx.xxx.49 1300 extendable

ip nat inside source static udp 10.10.10.5 1300 88.xxx.xxx.49 1300 extendable

etc.

ip nat inside destination list Polycom pool Polycom

ip route 0.0.0.0 0.0.0.0 77.xx.xx.170

---------

Where 88.xx.xx.49 is my static IP, while 77.xx.xx.170 is my default gateway.

Any advice on what I am doing wrong?

Hello Ben,

Did you apply the command "ip nat inside" and "ip nat outside" on the LAN and WAN ports respectively? And also I hope you must have defined an access-list with the name Polycom.

I can't think of any other reason!

Hope that helps,

Talha
