RE: [Users] FreeSWAN <-> Windows 2K - IPSEC tunnels - Failed oakley negotiation

Did you check your "filters" in the IPSec policy stuff?

Does it have a filter that matches packets destined for a remote subnet?

Also, I'm not really clear on what you are trying to do. Are you trying to talk to a subnet behind freeswan, from the win2k box, or are you trying to connect 2 subnets, one behind win2k and one behind freeswan?

I am using the win2k IPSec whatnot to connect to a Netscreen100, and talk to 2 subnets behind it. But I've not used win2k to connect to freeswan. Still, I would imagine that most things are similar.
