How to check the target of source ip / destiantion ip if it is dropped due to AntiSpoofing?

[BlueGrass]

Dear All,

Just find a question here.

We are using the Checkpoint Gateway as Second tier Firewall.

Every time we get "Network Topology" from the Gateway objects, the Anti Spoofing will enable again.

And then the internet traffic is dropped due to the Anti-Spoofing.

but if we check out the traffic log, seems we just got the "allow" message but not "Drop due to Spoofing..."

Please advise.

BTW, how can we disable the Anti-Spoofing forever?
