src_port below 1024 (NFS)

[EVAgames]

Hello everyone. Can't really remember when it started, but with some 24.7 update.

I'm using NAS behind OPNsense and doing 2049 port (TCP/UDP) forward on WAN. Using NFS4 so everything seems fine.

So today I've noticed that when you connecting to 2049 port and using source port above 1024 - I can see traffic on firewall log. But when src_port is 848 - can't even see the traffic.

Opened few other ports and same behavior. When source port is below 1024 - no traffic on firewall log. When src_port is 1025 - port [tcp/nfsd] succeeded.

Were there any changes that could address this? I've read few changelogs but didn't find anything.
