Hi,
SQL Server behind my Mikrotik router needs to connect to an external server on port 8545.

When using my Sonicwall, it works perfectly. Upgraded to the mikrotik, and it stopped working.

Any idea what kind of rule I’d need?

Thanks,

Do you accept established and related connections on forward chain? If not, you should.

See the screenshot. I’m using the default rules, which accept established and related.

Figured it out.

I had a NAT rule forwarding all traffic directed at port 8545, to an internal server.
Since I didn’t include a source for the traffic, when I tried accessing a remote server on port 8545 it failed.

Fixed this rule with a source IP, and it now works.
