As the subject states, I have a IPsec VPN connecting to my work and after setting up a IPv6-in-v4 tunnel using a GIF interface, it no longer works. It looks to me like the route somehow got messed up.
If I try to ping a remote (private) IP, I get a "Destination Net Unreachable" returned from my ISPs router, which is telling me OPNSense is putting it out to WAN rather than over the IPSec tunnel.
I cant figure out why that is, or what I need to change to fix that. The tunnel shows that is is up and installed so it should work. I even restarted the tunnel several times.
Any assistance is appreciated.

I went ahead and deleted the phase 2+1 config after copying down the settings, and put them back in the router, but I still have no connectivity to the remote net. Phase 2 shows its installed so everything should just work, but nothing is going through. Again trying to ping the remote IP range shows the packets are getting rejected by an upstream ISP router because its an unroutable rfc1918 address that OPNsense for some bizarre reason is deciding to drop directly on the wire instead of into the VPN.
