Hi all. Thanks for a lot of good info / help.


1. When I add a rule in Inbound NAT I X for auto add firewall rule
2. I test the connection with grc.com and from a remote site

And it stil does not work. I know it should only be to add the rule to
Inbound NAT and add to the firewall rule. And then it shuld work. But
no..... It does not. It works fine with other simelar systems based on linux
or unix. So could it be the hardware ???? Strange I have full access out to
the internet if that is the fault. :)

Paal B.

I have been using m0n0wall for a while. I have never had to enter two rules
in the way you describe. I believe reason a) is to blame. I have always just
entered a rule on the Inbound NAT page and checked the "auto add firewall
rule" box. 

When you say you have to enter two rules, are you referring to having to add
the NAT rule and the firewall rule? If so, without checking the "auto add
firewall rule" when you create the Inbound NAT rule, you are correct you
will need to add a firewall rule separately.
