Hi - I am having a mare of a day here with this ASA ... I wonder if anyone can help

I basically have 2 domains running on the network and they all go via seperate ports on the cisco

domain1 - eth/1 - internal 10.0.9.x
domain2 - eth/2 - internal 10.0.1.x

I do not want the networks to communicate generally but the mailserver that hosts both is on the 10.0.1.x network

I have 6 usable Ip addresses 81.2.23.20-25 and I have configured eth/1 to listen for incoming traffic on .21 and the rest on .22-24

All traffic for some reason goes out via .22 (ideally I would like the eth/1 to send all traffic via .21 - but its not the end of the world) but the issue currently is when someone on the 10.0.9.x networks wants their email they resolve the IP address for the server (eg:mail.net) and this resolves 81.2.23.20 for example but they can never connect

users on the 10.0.1.x network are OK as in DNS i have an IP for the  mailserver which sits on the .1 network

I suspect this is because all the addresses .20 - .25 are really on the same network


I see there is a option to allow connections between 2 networks wit the same security weighting but I really dont want them to communcate generally but as both companies are on the same mail server .. they need to just for this (but happy to use the external address)

Please does anyone have an idea on how to do this !!!
