Firewall/NAT

Wow, lots of information.

I tired to enable advanced outboound and it disabled all my of business's internet connection!! Not good for the webservers 

It came back once I disabled it, but....what's that all about?

Perhaps I'm not adding a rule? Am I suppose to add rules in the Outbound?

Just noticed that you said you had a "Auto Rule for LAN".

I don't have that?

It may be because I'm using version 1.3. For your information, I've attached screenshots of the my Outbound NAT rules. If you don't have an Outbound NAT rule, you'll need to make your own. See attached screenshot.

My test LAN uses 192.168.1.0/24 and the DMZ is 192.168.13.0/24. I created Outbound NAT rules for both.

These outbound NAT rules may have a negative effect for certain programs, but I can't confirm it (" two clients behind NAT cannot communicate with the same server at the same time using the same source ports").

Did you try downgrading to 1.233? I discovered my problem is OK with 1.233 but fails with 1.234.
