I have a VPS which has venet0 and venet0:0 interfaces with public ipv4 being on venet0:0. Now when i start openswan it gives me error that i can't find public interface. I am using NETKEY. I tried to specify interfaces="ipsec0=venet0:0" but it gives me ipsec_setup: interface `ipsec0=eth0' not understood . Is there a way around this? Thanks
