Port Forward Troubles *solved*

Never mind. I deleted the rules and redid them and oddly they worked the second time around.

Thanks anyways!

I'm trying to expose some specific network items by forwarding specific ports on the WAN connection.

Basically, I've done the following:

NAT rule:

WAN TCP 912 192.168.4.99 80

Access rule:

TCP * 912 HTTP(80) *

The assumption is that I can expose several items like this by simply forwarding the proper ports. However, this is not working even though other ports (SMTP, IMAP and POP3) are working perfectly fine.

Any ideas?

TIA

You need not specify the 'source' port on the firewall rule in this case. It will try to match that from the client, and clients use randomized source ports.

You only need the destination port on the local IP. The "wan" port you are forwarding isn't relevant to the firewall rules, only the destination or "local" port.

Will give it a whirl when I get back to the office in a day on Saturday. Thanks.

BTW, bought the book and I'm reading through it. So far so good :)
