FreeBSD hop-gw.morning.ru 4.3-STABLE FreeBSD 4.3-STABLE #3: Sat May 19 12:34:21 KRAST 2001     root@hop-w.morning.ru:/usr/src/sys/compile/hop  i386

>Description:
using newly implemented feature 'me' of ipfw has a sideeffect for pointopoint interfaces -- the remote addr. is classified as ours (i.e., matches 'me')
>How-To-Repeat:
should have any PTP-interface and set your firewall up using 'me'.
>Fix:
avoid using INADDR_TO_IFP (/usr/src/sys/netinet/in_var.h) for 'me' feature in ip_fw.c cause it finds the corresponding interface for any kind of addresses without respect to is it remote or local.
