Check Point Firewall on NT 4 Server

Archived from groups: comp.security.firewalls (More info?)

Dear all,

I have VPN FW-1 4.1 on NT 4 Server. My network is working fine, have
few servers befind firewall including mail server. My NT Firewall
server has internal IP address and one public IP address. The problem
is, all the Internal PCs/Servers can ping my Firewall Server,
howerver, I can't ping the Internal PCs/Servers from NT Firewall
Server. The PDC is befind the firewall and NT Firewall Server joined
the domain with PDC. When I do a restart, it says I don't have a
connection between NT Firewall Server and PDC and say something like
'it will use cache connection'. However, everthing still works find
including e-mail server and VPN, etc. I would like to ask if this is
normal? Thanks for all your help in advance.

Mike
