about netclient:

local port has changed from  41320  to  33605

is it possible to avoid local port change?

not with UDP Hole Punching enabled. You have to set "Is Static" on, and then set the port manually. Though I believe this feature is currently not working and requires a bug fix

thanks! I'll try and see if the bug still exists

did you try this?

I tried indeed, sorry: I forgot to confirm. Indeed it fixes the port change 🙂
