bit of a newbie question, but this operates differently to what i'm used to.
It would appear that when passing traffic through the firewall it goes through the following path
- NAT: Where it translates the connection to the internal IP address & port
- Firewall ; Where you have to allow connections to the Internal IP & Port
Is this as expected? I'm used to it being the Firewall allows connection to the external IP and then gets passed to NAT to redirect.
I have also struggled with PAT, when using PAT what do I enable on the Firewall as the destination IP & port? Is it the IP/Port pre-NAT or post-NAT?
I'm sure this is noted somewhere but I just can't find it written as a simple flow of how the traffic is processed and am struggling to get a working system in this way?
Thanks for any guidance.
