Cisco 2801 - Port Forwarding

[tjamro]

The current setup we have is that our internet service goes into the Cisco 2801, and then the other port on the 2801 is the small subnet of external IP address given to use by our internet access provider.

We want to make sure port 2080 always forwards to xxx.xxx.149.18, but since i'm new to cisco i'm not really sure how to setup the access lists. We don't need to restrict ports on the Cisco because there are other devices on the subnet that need access to many different ports.

Our current config is :

interface FastEthernet0/0
ip address xxx.x.3.118 255.255.255.252
duplex auto
speed auto
!
interface FastEthernet0/1
ip address xxx.xx.149.17 255.255.255.240
duplex autoe debugging
network xxx.x.0.0
!
ip default-gateway xxx.x.3.117
ip classless
ip default-network xxx.x.0.0
ip route 0.0.0.0 0.0.0.0 xxx.x.3.117


I did the command show access-lists and nothing came up, so perhaps they are blank!!

Thanks in advance, and if you need more info i'll try to get it.

I see no access-lists there. The static NAT command is what you want. It translates to the private address and port from the outgoing interface. So we need to know what IP address the machine that needs 2080 is.

The server is on our internal side the SonicWall with an IP address of 10.0.0.5.

The SonicWall IP address is xxx.xx.208.18 and port forwarding has been setup correctly according to our vendor to forward port 2080 to 10.0.0.5.

So is that what you wanted? An access list won't forward ports only out an interface---it needs IP addresses to relate for source and destination. I am unclear on what you need...

According to the service provider that needs port 2080, we need the 2801 to forward all traffic from FE0/0 (internet) requesting port 2080 to forward to xxx.xx.208.18.
