Re: [FW-1] MAIL and LINUX



Hi,

   Your local.arp file isn't needed, that Windoze stuff. All you need
 is ARP and the Static Route. Maybe something is wrong with them, what
 happens if you telnet from the Internet to the STATIC Nat address of the
 mail server on port 25 ? Does it answer ? Something in the log viewer
 of the Firewall ?

Met vriendelijke groeten - Bien à vous - Kind regards

Subject: [FW-1] MAIL and LINUX


Hello,

I sent an email earlier regarding a mail problem with the firewall.  I
recently setup a RH 70 machine with 4.1 sp3.  Everything is working fine
except for mail.  We have one static NAT rule for our SMTP server
(exchange).  I added the arps and Static Route to the rc.local file and
they seem to work great, also added the local.arp file to STATE dir.
The old firewall that was setup was an NT 4 box that passes mail fine.
The moment I cut over to the linux server, no mail gets sent out or
received.  I do see accepts in our log viewer from our mail server to
random IP's, but no mail is leaving and no mail is returning.  From an
outside line, I can telnet to the static address on port 25 and I reach
the mail server.  WHAT AM I MISSING?

any help would be appreciated.

Thanks,

Aeon

PS.  I used automatic STATIC nat rules and i've checked them a couple
times.
