Description

This scenario was replicated on 3 PCs with various network cards on 2.01.

Enabling a CARP interface on a box with IGMPProxy running and receiving multicast traffic results in the box becoming unstable upon reboot. Once rebooted, the interfaces will come up briefly and eventually cease to pass traffic/assign IPs via DHCP. If rebooted a subsequent time, the same scenario repeats itself.

Repeated by:

Using 3 different machines, 2 i386 and 1 ia64 with various branded NICs.

Public IP passed to WAN
192.168.0.0/24 on LAN
UDP traffic permitted on WAN via Rule: UDP * * 224.0.0.0/4 * * NONE
On LAN - Default allow rule was edited, advanced options selected to allow IP with options - enable Multicast

CARP:

Firewall -> Virtual IP
Type = CARP
Interface = WAN
IP Address = Public /32
Virtual IP Password = whatever
VHID 1
Save

SSH int PFSense router to ping the upstream router using:
ping -c1 -S <CARP IP> <UPSTREAM IP>

So that the upstream 2Wire router detects the new virtual MAC address.

Reboot computer

About 5 minutes into working it will freeze and cease to pass traffic.
