Hello everyone,
I'm new to TINC. Today, I've started using it, and now I've a network on around 9 dedicated servers and 15+ VPS
into a single VPN. I switched from OpenVPN.
But, I've a problem adding another node to the VPN.
Basically this node is a VPS with two IPs, on a single eth0, with eth0 -> IP1, eth0:1 -> IP2. IP1 and IP2 are on
different subnets, so they have two different gateways. This is a CentOS 5 box, so I've edited ifcfg-eth0 and
ifcfg-eth0:1 and manually added GATEWAY=n.n.n.n statements for each IP (in each ifcfg-<interface> file).
But, TINC is unable to ping any other hosts. It seems to be a route problem caused by multiple default gateways,
one for each real public IP / subnet. May I need to add a default gateway for TINC ?!? How to do that ???
