Maybe it is possible > to launch second NATd for this interface? Hmm, I don't know if I understood correctly but you don't need to NAT if=20 you want to route from 172.16.0/24 to 10.10/16. Just NAT anything on tun0=20 from !192.168.54.107 to any. (And make sure gateway_enable=3D"YES", resp.=20 net.inet.ip.forwarding=3D1) You don't tell us whether you use IPFW, IPF or PF, but at least for the=20 latter two you could define more than one NAT rule! =2DHarry --nextPart2205921.ci1ND2OrJP Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (FreeBSD) iD8DBQBCf8oRBylq0S4AzzwRAoj1AJ9aZUpUnmzUo5vzpW80KFwP0Ko9HgCeINgn 0fKa6X02xKnsyQsQ8Nj/CtU= =i68/ -----END PGP SIGNATURE----- --nextPart2205921.ci1ND2OrJP--
