openswan / openvpn tunnel between 4 ubuntu servers
Hi all,
I have to configure ipsec / openvpn tunnel between 4 ubuntu machines.
lan ---- r1 >> r2 >> r3 >> r4 ---- lan
i configured openswan on all 4 and connected via ipsec, works fine, but problem is with routing, since i'm using netkey, there is no tunnel interface, unable to route traffic after second hop.
Please help me out doing this. is KLIPS and tunnel interface to configure routing.
or else any other way to do this. i have to do this only with 4 linux routers, no cisco.
thanks in advace.
