Hello all,
Currently we have deployed an Astaro V5 Firewall, while configuring SNAT for a specific IP we ran into the following problem, I couldn't find references / info in the manual in this regards and hope there is an fix for this.
The firewall itself has 1 physical interface with 5 vlan interfaces, of those 5 interfaces 4 are internal subnetted in the 172.29.2.0/23 network, on external interface with an public IP address in a /28 network x.x.36.42.
I configured the DNAT rules in such a way that incoming https and smtp on x.x.36.43 is directed towards 2 diffrent systems. (We are not using smtp content scanning/filtering). For the outgoing SMTP i configured an other DNAT/SNAT rule: mail.int -> any / all -> none mail.ext
The problem now is that when the server mail.int is connected towards an other internal network the SRC 172.29.2.X ip is translated to the external x.x.36.43 although the destination is internal. I'm therefor looking for an SNAT translation like mail.int -> "NOT internal nets" / all -> none mail.ext
Is this possible/supported ?
Thanks in advance
Stijn Jonker
