Hello list:
Tried a migration (fresh install) of FW-1 4.1 last night on a Windows
2000 SP 2 Compaq Proliant 1600.
Thought the install went well until my users were not able to receive any
e-mail, sending e-mail was ok.
Here is a quick Config rundown:
Checkpoint FW-1 4.1 SP5 on Enforcement Module (Windows 2000 SVR SP2)
Checkpoint FW-1 on the GUI Client and Management Module (Windows 2000
SVR SP2)
This was a fresh install. I
opted to manage my routes manually; I already had a text printout of the routes
from my NT 4.0 Firewall-1 (4.0)
Basically the first few rules look as such
Firewall -----> Management Accept
Management -----> Firewall Accept
ANY -----> SMTP_SVR(NAT’ed) Accept
SMTP_SVR(NAT’ed) -----> Outside_world Accept
I also had the necessary DNS rules installed so the Mail server could do
a DNS lookup. The strange thing is
that on the Log you could see the Firewall pass the request from the public IP
of the SMTP server to the NAT’ed address but the SMTP server never received the
e-mail.
I think this is a routing problem; I am new to routing with Windows
2000. Any ideas or a thought on
what to look at next is greatly appreciated.
