Hi all,
im using freebsd 7.0 + gif interfaces + racoon + pf to filter stuff on
my box. After upgrading to freebsd 7.0 I see some strange behavior. I
see packets get dropped because of bad hdr length. The problems only
seems to happen on traffic between the local nets and nets routed via
ipsec. Here is a tcpdump snipped:
block in on em5: 192.168.175.4.1107 > 192.168.116.6.22: tcp 544 [bad
hdr length 12 - too short, < 20]
gif interface:
gif5: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> metric 0 mtu 1402
tunnel inet 213.157.17.67 --> 213.23.198.131
inet 192.168.116.1 --> 192.168.175.1 netmask 0xffffff00
Any help is welcome.
Thx
Norman
