FreeBSD Port: freevrrpd-0.8.6

[Pawel Worach]

Hi!

Running freevrrpd 0.8.6 on 4.8-release floods the syslog
with (according to me) invalid messages.

The freebsd vrrp box pair is in a DMZ with Nokia IPSO Firewalls
that also use vrrp for reduncancy. My guess is that freevrrpd
doesn't like seeing the vrrp traffic from the firewalls and
floods syslog with this:
Apr 20 18:34:45 fwnatb freevrrpd[199]: checksum of vrrp packet is invalid.
Packet is discarded !
Apr 20 18:35:16 fwnatb last message repeated 62 times
Apr 20 18:37:17 fwnatb last message repeated 242 times
<and this goes on and on for ever>

Traffic on the subnet looks like this:
(freebsd box is fwnatb, the other two are the IPSO firewalls)
18:43:23.316151 fwnatb > 224.0.0.18: VRRPv2-advertisement 28: vrid=70
prio=254 authtype=none intvl=1
18:43:23.439140 fw1 > 224.0.0.18: VRRPv2-advertisement 20: vrid=65 prio=150
authtype=none intvl=1 [tos 0xc0] 
18:43:24.315074 fw2 > 224.0.0.18: VRRPv2-advertisement 8: vrid=94 prio=100
authtype=none intvl=1 [tos 0xc0] 
18:43:24.315852 fwnatb > 224.0.0.18: VRRPv2-advertisement 28: vrid=70
prio=254 authtype=none intvl=1
18:43:24.439129 fw1 > 224.0.0.18: VRRPv2-advertisement 20: vrid=65 prio=150
authtype=none intvl=1 [tos 0xc0] 
18:43:25.315096 fw2 > 224.0.0.18: VRRPv2-advertisement 8: vrid=94 prio=100
authtype=none intvl=1 [tos 0xc0] 

I have no idea why freevrrpd even cares about the packets that
are using a vrid that's not even in freevrrpd's configuration.

Any ideas how to make this madness stop?
