In version 900044 field ip->ip_len has been changed to carry all length of packet (previosly it was be length without header's length), and all program, which use ip->ip_len, must be corrected. Unfortunately, igmpproxy doesn't update till 2009 year and don't work on FreeBSD 9/10. If you try to use igmpproxy now, /var/log/message you can see : Apr 25 01:13:57 gw igmpproxy[68438]: received packet from 192.168.199.1 shorter (40 bytes) than hdr+data length (24+10216) Apr 25 01:13:58 gw igmpproxy[68438]: received packet from 192.168.199.10 shorter (32 bytes) than hdr+data length (24+8168) Apr 25 01:13:59 gw igmpproxy[68438]: received packet from 192.168.199.1 shorter (40 bytes) than hdr+data length (24+10216) Apr 25 01:14:00 gw igmpproxy[68438]: received packet from 192.168.199.206 shorter (28 bytes) than hdr+data length (20+7148) >How-To-Repeat: Install port igmpproxy, and try to use it. >Fix: # This is a shell archive.
