Re: [FW-1] Anti-spoofing



You say nothing about _how_ you set up the anti-spoofing.
 
If you search the list archive at (for instance)
 
you will find numerous messages that explain
the basic anti-spoofing settings.
 
They are:
Internal IF 1: This Net
Internal IF 2: This Net
etc ....
DMZ:    This Net
External IF:  Others
 
If you use NAT, you must create a group consisting of each interface's network,
plus any NAT addresses that may apply to that interface, and insert
that groups as valid addresses in the anti-spoofing settings.
 
Cheers,
Anders :)

Subject: [FW-1] Anti-spoofing

Hi!
 
I am testing NG. If I enable the Anti-spoofing protection the firewall drops pings from machines in one interface to another. I saw in the logs that it was because of spoofing but I was not doing spoofing. Why is this happenning? Any idea of how to enable Anti-spoofing protection and not having this problem?
 
Thanks very much,
 
Beatriz
