I am using mpd from the ports. It uses the netgraph interface and works very well connecting the GRE VPN stuff in Win95/98/2000 to our 4.1 server. I would imagine it will work with your router. The documentation is a little spotty, but the port maintainer gave me some good help, as I will if you want to pursue this. The netgraph device is more efficient than the tun device, as it is more closely coupled to kernel networking. You don't need to put netgraph in the kernel. It is loaded on demand as a kernel module. -Jim Durham > Brent > > ----- Original Message ----- > From: Caleb Walker <cwalker@cwalk.org> > To: Brent <brentb@loa.com>; <freebsd-questions@FreeBSD.ORG> > Sent: Friday, April 20, 2001 12:32 AM > Subject: Re: gre-tunneling help > > > What are you trying to do?
