There's some RFC somewhere that recommends hiding the internal ports. So Jool does it. But that's probably not really important right now. > So if ports cannot be shared with NAT44, are the range of ports that > jool does use somehow reserved so that NAT44 doesn't tromp on them? If I remember my old research, and it's still relevant, NAT44 uses 32768-61000 by default, so Jool uses 61001-65535 by default. Something like that. But that's just the default config. You can add all the ports you want to Jool through pool4 commands.

Any of the following will destroy your instance: - jool instance remove ilinx - modprobe -r jool - shutting down or rebooting the system On Thu, Mar 17, 2022 at 4:35 PM Brian J.
