Hide NAT on virtual IP - 1550

[petermatuska]

Hi ,

I have a problem with PAT - Hide NAT on 1550, R80.20.02

I have couple of internal subnets /24 and a public /29 subnet on an outside interface. I have ticked Hide nat for outgoing traffic and all is fine. Internet works. The problem is when I want to hide one of the internal /24 subnet behind a public IP which is not configured on the interface but is within the public subnet.

I setup the NAT rule where original source is desired /24 subnet and translated source is specific public IP. Hide multiple sources... and Server as an arp proxy... are ticked. The problem is that returning traffic is not seen on FW. I see on a destination server that the ping arrives with correct public IP and the reply is sent back, but thats all.

Believe this might be a bug and should be worked with the TAC.

I would first update firmware to 

R80.20.05 (992001174)

Hi,
I havent tried upgrade yet (fw is in production now), but
this helped: https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solut...

Once the R80.20.05 (992001174) is suggested version, I will upgrade it.
thank you
