Congratulation. Since the last EuroBSD 2002 conference, there are 2 architectures to supp= ort=20 VPNs with FreeBSD : your patch and the Riccardo Scandariato one=20 (http://softeng.polito.it/freebsd/) that is very good too. =46rom a VPN point of view, how could both projects be compared ? Do you think that both projects could be merged or are there too much=20 differences between your two projects ?
