Perle 494 and 594 controller TCP and UDP ports (Firewall)

Go Back Printable Version Suggest New Article Bookmark This Article

Issue:

Which ports and protocol need to be open in a firewall to allow the Perle 594 or 494 controller to remain up and operational ?

Cause:
APPC over AnyNet requires the usage of Multiprotocol Transport Networking (MPTN). MPTN uses specific UDP and TCP ports for communications.

Solution:

The ports that need to be open in a firewall to allow the Perle controller to remain up and operational are the following:

TCP - source OR destination port 397

UDP - source and destination port 397

ICMP - Echo (ping) from the controller and echo-reply(ping reply) from the AS/400

Note: sessions initiated by the Perle (controller sessions), have a source TCP port of 397 and a destination port of 1024-65,535 and any sessions initiated by the AS/400 (ie. NWS and PRT sessions) will have a source TCP port of 397 and a destination of 1025-65,535. So you need to account for both of these in the firewall entry.
