  1. Help needed with Watchguard Firebox III config

    I have (2) SMTP servers behind a Watchguard III Firewall. The SMTP
    servers are on different domains.

    SMTP-1 has a private address of 192.168.1.100 and a public address of
    207.x.x.148
    SMTP-2 has a private address of 192.168.1.95 and a public address of
    207.x.x.146

    I configured the Watchguard for 1-to-1 NAT.

    I am able to send and receive mail from both servers with the
    following excption: Email's sent from SMTP-2 to any address on SMTP-1
    are queued and never delivered.

    I am able to ping 192.168.1.100 (SMTP-1) from 192.168.1.95 (SMTP-2).
    I am unable to ping 207.x.x.148 (SMTP-1) from 192.168.1.95 (SMTP-2)

    Can someone point out what I'm missing?

    Thanks

    Simple: functional *internal* DNS.
