firewall rule

Hello m_k,
Create a new firewall rule. Rule is from internal to external. and choice create log. and assign to user. Therefore firewall will log everything incoming and outgoing. Than you can see which port used.

Best Regards.

I don't think SEPM can give you the information about the ports.You can add this as an idea in the Idea section.

Please don't forget to mark your thread solved with whatever answer helped you : ) Thanks & Regards Aravind

Firewall Rule

Hello again,
In the Sep Manager Choice Policies>Firewall Policy> Create new Rule.
Choice Blank Rule.
When you create rule move it first line. and choice Log. (you can see picture below)
Than Assign the policy to user which you want to follow.
Update Client policy and open user log file in Sep Cleint.
Regards.
Fatih

Please note you will want to

Please note you will want to only temporarily use this logging policy. I know from experience as this amount of logging will spike the CPU utilization and disk I/O.
