On-premise Gateway attempting port 137

Our firewall logs show our on-premise gateway attempting to use port 137.

It's not one of the listed ports so is being blocked (deliberately).

Should it be communicating over port 137?

Should we open up that port?

hi, @RGI

You should open up TCP 443 (default), 5671, 5672, 9350 through 9354.

and It is recommended that you whitelist the IP addresses, for your data region, in your firewall.

Re: On-premise Gateway attempting port 137

Thanks for the reply but it doesn't actually answer my question.

I already have all of those ports open.



The firewall team have reported that the gateway is attempting to communicate over port 137. Is this normal?
