I need to open this port in Fortigate:

443 PSOM/TLS Outbound Data sharing sessions

But i dont know where I can open. I created a Custom Service, chose the option of TCP, but do not know if it's the right thing.

Does anyone know how can I open this port?

The FortiGate doesn't care which protocol is running over the port 443, so you just need to create a policy and select the corresponding interfaces/addresses and as service you can select HTTPS. If it's a policy from internal network to WAN, be sure to select NAT also

  • To add to this, if you already have a policy in place for that source/destination, you can simply add the HTTPS service to the existing policy. Apr 5, 2014 at 22:09
