SmoothWall Firewall What ports for Spark IM?

I just recently installed a smoothwall Firewall and can not figure out what ports i need to forward?

I can’t seem to find any documentation on this anywhere here

Can anyone help?

Does anyone else use smoothwall and Spark?

Solved, did not like the IM Proxy Setting Man in the Middle Attack.

Once I turned off that feature on smoothwall it’s now working fine…
