Hello

I am trying to configure my 1811W firewall config via SDM to send inbound smtp traffic to my exchange server...easy setup as I am a small copany with a small network yet its been about 6 hrs now and I cant get it to work.

Info

I have two interfaces - one WAN IP (FE1) and LAN IP configured on 1811

FW Policies/ACL/rules are as follows:

From WAN/FE1 to LAN

-FROM ANY to the LAN IP address of my Exchange Server for SMTP at Port 25

-From ANY to the LAN IP Address of my 1811 Router for SMTP at Port 25

The only denies I have are

From 0.0.0.0 to any and the other private addresses

Do I have to do anything else??

HELP!! Thanks in advance

Hi it still doesnt work

I enclosed my latest config

This PAT change is now causing an IP address conflict with my exchange server!Help

You mentioned the statement

ip nat inside source static tcp 25 interface fastethernet1 25

above

but when I configure it on the outside address it lists

ip nat outside source static tcp 25 interface fastethernet1 25

in the config file

should it be

ip nat outside source static tcp 25 interface fastethernet1 25

or

ip nat inside source static tcp 25 interface fastethernet1 25???

thx
