message information address spoofing

Solanin — Tue, 11 Aug 2020 07:06:46 GMT

Hello guys,

Here's my problem:

the range 10.136.1.0/24 go trough without problem to the internet from the internal.
I would like to add a new range 10.137.1.0/24. But every communication are drop with the message information : address spoofing.

I've added the new range to the routing table with the internal interface gateway, like the 10.136.1.0 range and i added also the range to the anti-spoofing group. What am i missing ?

We use a smart console R80.30 to manage all of our firewall checkpoint and the firewall is a stand alone running on R75.46

Thank you in advance for your input,
