2611 used as internet edge router

[hoinvip]

Can anyone help me please?

We have a Cisco 2611 router which will be used as the last hop to our ISP. We are intending to use NAT on this box and have our inside addresses running on a 172.16.x.x network.

Our outside IP is an internet "legal" IP address. What I need to do is establish a static route for our mail server running SMTP port 25 through this router.

Also, I want to provide another static route out for web browsing.

Can someone give me a pointer on the command syntaxes I need for this please?

TIA!

You need to use something called "static NAT mapping"

! this line sets up the one IP address to be shared on the WAN port using access list 1
ip nat inside source list 1 interface Ethernet1 overload
!
!this line sets up the static NAT for SMTP to be directed at 192.168.50.3 specificly from 192.168.1.2(WAN)
ip nat inside source static tcp 192.168.50.3 49 192.168.1.2 25 extendable

Go to Cisco's site and do a search on static NAT
