Port forwarding isn't working anymore

Hi all,

I'm running an astaro UTM9/Firmware version: 9.004-33 and am having a problem since yesterday. Changes were adding SSL remote access for some smartphones which is perfectly working. But now I saw that my local webserver cannot be reached anymore from outside.

I have a single DNAT-Rule to forward extern port 5001 to my local web server like that:

Rule #1
Under Network Protection/NAT/NAT:
Rule Type: DNAT
Matching Condition
For Traffic from: Any
Going to: external
Using Service: 5001/TCP
Action
Change the destination to: local IP (sth. like 192.168.0.55)
and the service to: HTTP
Automatic Firewall rule: checked

There must be a side effect or something else which blocks that traffic. Adding a rule like this and enabling both of them works:

Rule #2
Under Network Protection/NAT/NAT:
Rule Type: DNAT
Matching Condition
For Traffic from: Any
Going to: external
Using Service: HTTP
Action
Change the destination to: local IP (sth. like 192.168.0.55)
Automatic Firewall rule: checked

So Rule #1 alone doesn't work (no access with external port 5001), but Rule #2 does (acces with standard HTTP-Port 80).

If I enable both rules access is possible with external port 5001 OR 80.

So where is the error?

Thanks for your help.

  • Does "latest firmware" = 9.004-34?

    When you say "Port Forwarding not working," do you mean that you have an unchanged DNAT that's no longer working, or that a new one isn't working?

    Please [Go Advanced] below and attach a picture of the DNAT

    Cheers - Bob

  • A new one is not working.

    Also it does not matter if I check "automatic firewall rule" or not.
