I have a setup where the virtualization (KVM) combined with the networking does present a IPv6 def-gw as both an fe80::<predictable number here> and the more normal 2001:a:b:c:d::1/64 and where the 2001-v6 ip works far better on virtual machines due to redundancy mac sync things on the network side, and since the ndp list showed the fe80::1 had a VRRP/CARP-lookalike mac, it could be the same.
In my case both bsd and linux IPv6-using VMs suffer from ndp "drops" where it can take seconds for the discovery to figure the mac address out again after a drop. So if you can divine what the "real" v6 ip is of the default-gw, try setting this hard in the conf or /etc/mygate and retry v6.
