I have two NAT questions for you today:
- I am replacing a Cisco PIX with an Astaro base firewall. I have a class C world-routable subnet on the external interface (they were given the address space when the getting was good). The PIX that I am replacing currently will NAT any internal address to a range of external IP addresses, rather than a single IP address. I didn't see any clear way to accomplish this using the Masquerade section. Has anyone done this or have any advice on how I might accomplish this?
- I am trying to replicate the same behavior as the PIX in regards to static NAT. I want to redirect incoming requests on a specific external IP address to an internal host. I also want this internal host to appear as though it is that same external Ip address when initiating communication outbound. I assume I have to use 2 statements (one for DNAT of the incoming requests and one for SNAT of the outgoing requests) but that didn't work too well. Do I accomplish this via a DNAT and a Masquerade?
Any help and / or advice is much appreciated.
Thanks!
Dave
