Firewall Rules: Single port not working

Security Firewall Rules
1

Dear IpFire Community. I’m turning to you because I’ve had a problem with a couple of IpFire installations. It turns out that in the Firewall rules, I have addressed some ports such as 80, 1433, 443. The thing is that no matter how much I check it doesn’t work, unless I put a rule of filtering absolutely everything to an IP. That’s how it works. It’s very strange because I have a couple of servers with IPFire that with the same configuration works well. Each port to the specific IP.

But I’ve already had 3 installations in which after hours of frustration, I’ve had to filter everything to the same IP. Has it happened to anyone?

What kind of rules are you speaking of?
Blocking, port forward, redirect?

3

Port forward.

Could you please show your rules?
Systems that work, systems that do not work.

Those ports all go to the same IP, and it doesn’t work, until you add rule 13, which opens all ports to that IP.

Source-Port must be empty.

BTW: It helps much, to switch the WUI language to English for page posting.
I had to change to spanish to compare your rules to mine. :wink:

IPFire has it’s own translation system for messages/WUI pages. For this task I don’t need Google. :wink:
