Port forwarding works - except for 1 port in particular

Hi all – first post, using an inheritied RB450G running 5.20.

Taught myself some ROS via the great wikis and tutorials and managed to get some interfaces, IP, fw and nat rules setup and everything working peachy. Except there is 1 service im port forwarding and it does not work. Fails everytime.

ive port forwarded 3 www servers and 1 and 2 work, but #3 is no dice.

each rule is identical besides obv internal IP.

Now im not sure how to provide the router info like export the rules to share my config? If you can tell me ill attach to this post.

Many thanks guys. Very excited using Mikrotik!

If only one rules is not working then check the default gateway settings on the device that is targeted by the third (non-working) rule.

Hiyo – turns out it was an upstream fw utilising the port in question.

Thanks for your help though!
