1:1 NAT Question, port forward and outbound rule
« on: August 20, 2010, 04:58:25 am »
I have a need for 1:1 NAT using one public IP address to accept traffic on a particular port and send it internally to another port, which seems simple enough.

I also need outbound traffic destined for a particular CIDR to use a particular public IP address.

I see 1:1 NAT is not supported with NAT reflection. Are there any ways around this?

This is normal port forwarding and not 1:1 NAT.

Firewall --> NAT --> outbound.
Enable manual rule generation and you can create rules to NAT as you want.

For reflection:

We do what we must, because we can.
