I'm using a Netopia Router and am using the built in firewall with
NAT. I have five external IP's, and I understand how to map those to
the internal NAT'd IP's, the question is..
When I am declaring rules for the firewall for inbound, do I use the
external IP's, or the NAT'd IP's. I guess I'm not sure where NAT fits
in the chain. I'm doing some ****t mapping between external and
internal, so ****t 80 on the external IP may map to 5000 on the NAT IP.
I've got it working, but I'm not 100% I did it right and want to
verify I haven't opened a hole.
As an example:
extern 205.206.207.208 ****t 80
NAT 192.168.1.1 ****t 443
Firewall rule on extern or NAT?
2nd. What about outbound filtering? Firewall on extern or NAT?
Thanks in advance!
