That port 4300 would be an outbound port from your IBM i. Much like port 80 for your browsing. No telling what port it will connect to on the local side, but the requester (your host) is calling out to 4300. The packet on the way out will tell the firewall which port it expects a reply on, and the firewall will be smart enough to allow the replies to come through.

When I start a session using STRRSESVR I see port 4300 active on my laptop but not on the iSeries.

I'm trying to run this command and I'm fairly certain the connection is being blocked by a firewall. I can run the command on System A which I know is not blocked and it works but when I run the command on System B which I know is behind a firewall it times out. I noticed in a comm trace on System B that it was using source port 28760, how do I know which port it's going to use? How to I know what to tell the firewall guys to allow? Thanks.
I see STRRSESVR on port 4300. If that's not right we should fix the
