--- Comment #5 from Paul Webster <paul.g.webster@googlemail.com> ---
I forgot sysctl.conf for the host:

root@de1:~ # cat /etc/sysctl.conf
# $FreeBSD$
#
#  This file is read when going to multi-user and its contents piped thru
#  ``sysctl'' to adjust kernel values.  ``man 5 sysctl.conf'' for details.
#

# Uncomment this to prevent users from seeing information about processes that
# are being run under another UID.
#security.bsd.see_other_uids=0
net.inet.ip.forwarding=1                   # Enable IP forwarding between
interfaces
net.link.bridge.pfil_onlyip=0              # Only pass IP packets when pfil is
enabled
net.link.bridge.pfil_bridge=0              # Packet filter on the bridge
interface
net.link.bridge.pfil_member=0              # Packet filter on the member
interface
security.bsd.unprivileged_read_msgbuf=0

# Random ip id's
net.inet.ip.random_id=1

# No idea something to do with ipv6
net.inet6.ip6.rfc6204w3=1
