I have IP spoofing protection enabled on PaloAlto but it is not effective due to the following reason:
My external Interface IP is 1.2.3.1/24 . The spoofed attacks are coming from a fictitious source IP for e.g. 1.2.3.25 destined to 1.2.3.50(web server). As per Palo's IP spoofing definition, this is not blocked because 1.2.3.25 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 1.2.3.0/24 subnet.
Has anyone implemented this? Am I right in my approach?
Thanks.

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.
