It would be great to see a RPC ALG to allow certain UUIDs-to-port-mappings to be allowed through the firewall.
This is a feature available on juniper we thought is useful.
Thanks for the request.
We have a few existing feature requests that are open to support RPC. They're as follows:
FBX-4651 - SUN-RPC
FBX-16085 - DCE-RPC
Looking at Juniper's docs for that feature, those two should cover the same functionality.
Are either of those the features you're looking to use?
