I'm setting up a VPN site-to-site link from a m0n0wall firewall to a debian server:
http://doc.m0n0.ch/handbook/examplevpn-freeswan.html
http://www.freeswan.org/freeswan_trees/freeswan-1.99/doc/manpage.d/ipsec.conf.5.html
Its not working... though one the freeswan side I'm getting this error:
FATAL: Error inserting xfrm4_tunnel (/lib/modules/2.6.16-xen/kernel/net/ipv4/xfrm4_tunnel.ko): Resource temporarily unavailable
Time to buy another netgate m1n1wall!
