Ok, I will explain why I need this
I have 2 ISP and 2 firewall and I want to have 2 MX records, one per
firewall/ISP
So, the map look like this
ISP1/FW1
192.168.0.1
LAN
MailSrvr 192.168.0.110 (deafult gw 192.168.0.1)
ISP2/FW2 192.168.0.4
The problem is that the Mail server have 1 default gw, 192.168.0.1 and when
a packet comes from ISP2 the mail server return the packet to the ISP1
because the default gw. This happens because the mail server receive a
packet from a External IP, so the connection SYN_SENT in my mail server is
to a external IP.-
So, how can I fix it? I think that one solution is that all the connection
to the mail server thought FW1 or FW2 are masq with the internal IP, in the
situation the mail sevrer CAN return the packet to the Internal IP.
