Ineffective IP spoofing protection

L4 Transporter

I have IP spoofing protection enabled on PaloAlto but it is not effective due to the following reason:


My external Interface IP is . The spoofed attacks are coming from a fictitious source IP for e.g. destined to server). As per Palo's IP spoofing definition, this is not blocked because is routable over that interface. I am considering to write an ACL on the neighboring router that says block all inbound connections with source IP in subnet. 


Has anyone implemented this? Am I right in my approach?




Yeah, I think I'm left with that one option only for now.

Sorry for not wording the question properly. Thanks so much for your help.
