I have a new OpenVPNas server running on CentOS 7 (Not married to CentOS 7). That I working on replacing an expensive Commercial VPN that has a Public Static IP. Being that the OpenVPNas server is what amounts to my private VPN Server I just need to forward a couple of ports to a static internal VPN address to replace the Commercial Server.
I have the VPN Client setup and I can ping from the Server to the Client's static IP and from the Static IP to the server's Public IP and beyond.
I want the following ports on the server's IP forwarded/NAT'd/Masqueraded to the internal VPN.
Public TCP 80 ie Server Public's:80 -> 172.28.28.28:80
Public UDP Ports 2074-2093
Public TCP Ports 15425-15427
Public UDP Ports 5198-5200
Public TCP Ports 5198-5200
I have tried different route / iptables commands, but I have yet to figure out the magic bullet. I believe it's a simple process but the solution is eluding me. Via SSH the server can connect to the VPN port 80 and I get the client's via the VPN's web interface. So the basic routing is working as expected.
I can't figure out the magic routing a packet destined for port 80 in the server's page to Forwarding
[root@vpn ~]# sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 1
[root@vpn ~]# route -n
