I would love to see something analogous to Cisco's "VTI" and Juniper's "ST" interfaces for VPN; most major firewall vendors have something similar to this, even "weird" stuff like Palo Alto support this (and PA doesn't do IPsec+GRE so I have no other way to replicate it against pfSense).
I would like to see that. It'd require a good deal of work, as there are missing pieces in underlying bits. Not on the near future road map at least.
That's what I've been reading, apparently neither BSD or Linux have the correct tunnel interface existing on the OS, making this more complicated. That said, Ubiquiti has VTI in their gear, so it can't be too bad to do… I believe they are some form of *nix underneath, wonder if the source for this is open?
I may have to grab an EdgeRouter and stick it behind my pfSense box just for VPN purposes. (I'm not likely to ever ditch pfSense at the edge, unless someone else starts supporting UPnP/NAT-PMP, since I have game systems.)
