I am about to migrate a customer from a hosted checkpoint firewall to an active/passive ASA 5520 firewall.
I have got some prints from the configuration of the checkpoint firewall, which show that 4 public IP's are forwardet to the same IP on the inside (don't ask me why!!).
As far as i concern this is not possible on the ASA. I could solve the issue by using PAT, and only forwarding specific services, however my issue is, that I need UDP/53 (DNS) forwardet on 3 of the public IP's to the same server on the inside (again, I know this sounds crazy, but this is how it is set up on the current checkpoint firewall)..
Any help is greatly appreciated !!
