Is this possible using SLES as a router/firewall? I know it works with
some commercial firewalls. SonicWALL is one of them.


Firewall/router (sLES)
Public interface:
Private interface:

Email Server

Laptop/tablet/smart phone
Interface: local IP

Firewall configuration port forwarding: -->

From the Internet I can access the email server using
From the LAN I can access the email server using

From the *LAN* I *want* to access the email server using
so that the device configuration doesn't have to be changed for
onsite/offsite access. I know I can accomplish this by setting up
appropriate internal/external DNS entries but that is not what I am

Any ideas?
