Okay, Linux first...


Most distributions have a very detailed description on what you need to do to set up interfaces. For example, in Debian you find that information in https://wiki.debian.org/NetworkConfiguration.


Once you have the interfaces configured and one has a private and the other one has a public IP address, you must make sure that the routing works okay. The important point here is that the default route must use the public IP address, so that when you send a packet out, the host inserts the public IP address of the PBX. You can verify that with e.g. whatismyipaddress.com, for example by using "wget http://whatismyipaddress.com". It is definitively worth spending some time on making sure that the routing is fine; once that you have the routing set up you will enjoy out-of-question quality inside the LAN (on the private IP address) and you will not have problems with NAT problems on the public IP address.


Another point that you should consider when running the PBX on public IP is that you are now exposing the PBX to scanners. You should definitively set the password policy of the PBX to at least medium, so that those scanners don't find trivial passwords. You should also have your email notification as administrator set up, so that you will get notified when the PBX blacklists IP addresses because of attacks. You can also have the PBX operate on a different UDP port than 5060; this makes it less probably that someone finds the PBX on public IP.
