Argh! The setsockopt numbers have changed; recompiling these utils
should fix it. FYI, the values used to be:

IP_FW_MASQ_INSERT 1344
IP_FW_MASQ_ADD 1345
IP_FW_MASQ_DEL 1346
IP_FW_MASQ_FLUSH 1347

They are now:

IP_FW_MASQ_INSERT 76
IP_FW_MASQ_ADD 77
IP_FW_MASQ_DEL 78
IP_FW_MASQ_FLUSH 79

ipautofw and ipportfw should probably try the old ones iff the new
ones fail with ENOPROTOOPT. Or the kernel could be changed to use the
old ones, or both.

Rusty.
