Hi,
Could someone tell me if there is a way to build a VPN(like) tunnel from
a FreeBSD machine acting as a VPN gateway to another machine acting as
another VPN gateway using normal IP packets that have only their data
payload encrypted. Of course there would have to be a way to setup the
tunnel and still retain the network addressing of each side of the VPN
I thought about some kind of IPIP tunneling but with data payload
encryption and some kind of key exchange for authentication
has anyone made or seen such a system yet ?
I do not want to use (I can't) AH and ESP for this because of some
technical contraints
