Feature Request - IPv4 over IPv6 bovpn tunnels
For our dual stack customers with remote sites, we build separate IPv4 and IPv6 bovpn tunnels over the primary link and a backup IPv4 tunnel over a secondary link (IPv6 Multi-WAN would be very helpful too! FBX-3998 - bump....) from the remote sites to the Core Firebox. We dual stack the IPv4 tunnel for protocol redundancy and preference IPv6 traffic over the bovpn tunnels accordingly, in the event of the remote site failing to reach the core over IPv6, traffic falls back to the primary then secondary IPv4 tunnels.
This past week we had an occurrence where the primary ISP had an outage over IPv4, the remote site IPv6 traffic continued over the primary link, however IPv4 failed over to the slower secondary link as designed, in this instance it would have been highly beneficial to have the ability to pass IPv4 traffic over the IPv6 bovpn tunnel without degrading IPv4 network performance.
Please consider implementing IPv4 over IPv6 tunnels, Thank you:)
