Routing traffic between 2 server with public IP

  • Hi,

    I have 2 servers with a public IP. There is site-to-site VPN created between them (transport mode , openswan). Lets say 1st server is front end, 2nd server is back end. On 2nd server openvpn is installed. I want to use 1st server as intermediate server for Openvpn meaning when i "dial" VPN on TCP port 443 on 1st server, request is routed trough the tunnel to actual VPN server where vpn connection will be established. VPN access on backend server will be denied for all traffic except the one coming from the IPsec tunnel. Can i achieve this using combination o iptables and routing? Can i force destination traffic trough the tunnel?
