Hi, When running 14.2-RELEASE VNET jails on 15-CURRENT ipfw does not work anymore in the jail.
Can this commit be involved? https://cgit.freebsd.org/src/commit/?id=4a77657cbc01 Copying the /sbin/ipfw binary from 15-CURRENT to /sbin in the 14.2 jail resolves the issue for me. Example errors: add net ::0.0.0.0: gateway ::1 ipfw: setsockopt(IP_FW_XDEL): Invalid argument ipfw: getsockopt(IP_FW_XADD): Invalid argument # ipfw show ipfw: retrieving config failed: Invalid argument Regards, Ronald.
