NAT issues with outbound port 25 on watchguard firebox lll
Posted on 2008-10-16
I have a similar question to a previously posted issue:
I have a watchguard firebox lll. I am having a problem with outgoing email to only a few domains like AOL. I think the issue is with NAT just not sure where.
I'm using watchguard policy manager 7.5.
My external interface is x.x.x.147
My external SMTP server is x.x.x.148
My internal SMTP server is 192.168.1.100
I have Enable Dynamic NAT checked with a single Dyamic NAT entry:
Enable Service-Based NAT is NOT checked
For 1-to-1 NAT i have the following entries:
# of Hosts = 1
NAT Base = x.x.x.148
Real Base = 192.168.1.100
When I send a message the header shows the sender's address as x.x.x.147 , shouldn't this be x.x.x.148?
