I'm looking for the best way to get an encrypted VPN set up that's
compatible with FreeBSD (on the permanent end), and clients running
Win 2k and RedHat Linux. I'd like to do this without having to buy
software from someone.
I have a suspicion that the limiting factor here is going to be the
Microsoft product. It appears as if it will do encrypted VPNs two
ways:
1. PPTP with proprietary MPPE encryption/compression
2. IPSec/l2tp proprietary hybrid
I looked in to option (1). It seems to be the easiest, with the
exception that apparently I need some proprietary code (as per the
following quote from the ng_mppc(4) manual page:
The MPPC protocol requires proprietary compression code available from
Hi/Fn (formerly STAC). These files must be obtained elsewhere and added
to the kernel sources before this node type will compile with the
NETGRAPH_MPPC_COMPRESSION option.
I haven't been able to find said code freely, for sale, or otherwise.
Option (2) looks even less likely. I've only been able to find one
implementation of l2tp, and it looks like it's still a pretty flaky
piece of software that hasn't been integrated with IPSec.
I'd appreciate any help I can get with this.
