When using KLIPS, the following routes are automatically established: 0.0.0.0/1 via 213.148.150.193 dev ipsec0 128.0.0.0/1 via 213.148.150.193 dev ipsec0 Removing them, let's me starting a connection without problems and routing works for me. What is the reason for those routes? May there be a sideeffect, when removing them, that I do not yet face? Norbert
