Hi,
I have a really strange problem down
here..
I have set up a firewall+nat+IPmasquerade with
IPtables (linux Redhat 7.1, kernel 2.4.x). Everything works fine with the new
web servers behind the NAT.
However, I have a MSExhange server to put from the
DMZ inside the LAN so I have changed the IP address to a LAN address
(192.168.2.*) and I have set up the NAT and the forwards needed rules
inside the firewall script.
It does not work at all I can't open any opened
port (80/110/25) BUT if I change the original address in the NAT rules of
this server then it works (let's say I move the address from .67 to .77).
So the firewall rules are correct.
The original address was well know by the DNS
primary (hosted) and secondary (hosted by my ISP), that's the only difference I
an see. Any idea before I change my MX address inside my DNS ??
Thanks a lot for your help
