Title: Looking at the log it seems like packets from a remote machine (NT 4 Server) sending packets out through a FW1v4

Working on this problem all evening and it’s making me crazy.

 

Looking at the log it seems like packets from a remote machine (NT 4 Server) sending packets out through a FW1v4.1-SP-1 firewall over the wan then through my FW1v4.1-SP-1 firewall get dropped.

 

Some packets get in ok some not, like:

 

Foo(Valid Address)           Nick(Valid Address)    # This gets blocked

 

But when the log shows:

 

Foo                  Nick(Valid Address)    # This gets in!

 

I am not using anti-spoofing on any interface.

 

Foo and Nick are in private networks and are using a static nat to a public address in our DMZ networks.

 

Both Firewalls are win NT 4.0 sp6a with three interfaces.

 

This seems to work at other sites with the same setup.

 

Thanks for your help!

 

Rob
