Hi,
Setup.
VLAN a -> connecys to ISP a and has a sixxs tunnel with IPv6 from sixxs addresses assigned.
VLAN b -> connected to ISP b and has native IPv6 addressing, addresses assigned from ISP b IPv6 address range.
Multipath rule VLAN b websurf -> any (4/6) -> interface ISP b.
Before I restarted the UTM, the IPv6 traffic from VLAN a would go down the sixxs tunnel.
Traffic IPv6 from VLAN b would go out ISP b link.
All very good.
I restarted the UTM, now the sixxs tunnel appears to be not operational ag I can't get any traffic down it.
All IPv6 testing (on either) interface shows the NAT'ed ISP b IPv6 address.
ISP a does know about IPV6, but does not allocate an IPv6 address.
I have disabled the ISP b link and all traffic stopped out that link as expected, but the sixxs tunnel did not carry any traffic.
I suspect I do need the sixxs tunnel to be at least active to get IPv6 traffic down the ISP a link.
How do I get the sixxs tunnel to carry traffic again?

The IPv4 traffic as far as I can tell goes the correct paths. Also Multipath doesn't seem to have an effect in this case. I have disabled the multipath rule and traffic appeared to go where it is supposed to. I also created a multip[ath rule for websurfing on ISP a with the aim of allowing only traffic from the correct network out when either interface fails. Yes, if ISP a link fails then all users of that network would be denied access. Same for ISP b link failure.
