Hairpin NAT is not working

Sacmaugacon — Wed, 06 Mar 2024 03:10:18 GMT

Hi teams,

I have device CP-6400, SMC R81.20

I need NAT hairpin server to access from both internal and external. I followed the link https://support.checkpoint.com/results/sk/sk110019

I was able to access from internet but not from internal. Configuration as attached photo.

hoping for your help

Thanks,

Try changing the translated source method to H-HIDE instead of S-STATIC for 10.3.80.1 in rule 10. You may also need to flip "translate destination on client side" to ON in your policy | global properties | NAT - manual NAT rules config.
