When requesting a firewall rule for the ports do they need to communicate bi-directional

[stuartjones]

All the documentation explicitly states the service port network and transport configuration but does not explain whether it should uni or bi directional for Unix, Windows, and SNMP specifically but all is needed.

[chuckm · Accepted solution]

Discovery firewall rules are uni-directional:

• The ServiceNow MID server initiates requests through the firewall to the target hosts and the target hosts only responds back to the MID Server.
• The target hosts behind the firewall does NOT initiate requests to the ServiceNow MID Server.

Mid Sever IP -------Firewall PORT Open -----HOST

Direction will be From Mid sever to HOST end.
