just a hint
even if your host is IPv4 only, is IPv6 enabled and do you have a 
fe80::xxx address?
just try to really disable IPv6 at host/kernel layer
e.g.

this entry in /etc/sysctl.conf
net.ipv6.conf.eth1.disable_ipv6 = 1

disables IPv6 at port eth1 at all, there is no fe80:xxx address at this 
port ...
