Outbound static, simple question

Unanswered Question
Nov 12th, 2008

Attached is my 1841 security router config. Simple question. Device 10.2.1.6 is my e-mail server & I want it staticly routed through the 65.103.52.172 address, such that when it sends outbound mail the recipients mail server sees it coming from 65.103.52.172. Right now outbound mail appears to be from 65.103.52.169, so I am missing something in this static route. Please advise.

I have this problem too.

What is this line doing -

ip nat inside source static 10.2.1.6 65.103.52.172 route-map nonat

more specifically what is the route-map for ?

Thanks for taking a look Jon!

I also have a VPN coming in through this router and there is some VPN traffic from the remote location that needs access to the 10.2.1.6 server. So, I think the route-map was added because of that VPN so that traffic over the VPN does not get NATed going back to the remote location.

I suspect this line in your config

ip nat inside source route-map nonat interface FastEthernet0/1 overload

is taking precedence over this one

ip nat inside source static tcp 10.2.1.6 25 65.103.52.172 25 extendable

Please do this out of production hours and verify that your VPN traffic still works.

not sure you need the second route-map statement as you are covered in the first one.

try changing -

ip nat inside source static 10.2.1.6 65.103.52.172 route-map nonat

to

ip nat inside source static 10.2.1.6 65.103.52.172 route-map nonat

try changing -

ip nat inside source static 10.2.1.6 65.103.52.172 route-map nonat

to

ip nat inside source static 10.2.1.6 65.103.52.172 route-map nonat

These lines you provided are exactly the same, what am I changing?

Sorry about that, sometimes i'm a bit absent minded :-)

ip nat inside source static 10.2.1.6 65.103.52.172 route-map nonat

to

ip nat inside source static 10.2.1.6 65.103.52.172
