I just want send some information (logwatch) directly from firewall to my
gmail. That secondary IP has a reverse name configured using the 201.xx.xx.4
IP. If i could send directly from firewall with this IP, It isn't necessary
do any configuration on mail server.
I will read more about SNAT end try some changes.
Thanks!
