Dual WAN HE Failover

[marjohn56]

I have a new FTTH connection, wonderful. 900Mbps symmetrical. The issue I have is that the with new connection everything is dhcp, no statics. Well I can mostly live with that. IPv6 though will cause me issues, so I am using an HE tunnel which gives me static, all good and dandy, works perfectly. I am going to keep my existing VDSL line for a while and I've set up a failover which is working.


The issue I'm coming up against a brick wall with is the HE ( GIF ) tunnel; it uses a fixed parent, so it can either be, in my case, igb0 for the FTTH connection or igb1 for the VDSL connection. Is there a way to make the same tunnel change parent interfaces when WAN 1 fails over to WAN 2?


If not, maybe worth looking into?
