Background:
I am currently running OpenWRT on a buffalo WZR-HP-AG300H and using OpenVPN to connect to a VPN service. When connected to the VPN a TUN device is created and assigned a class A IP from the VPN server and then all the traffic in/out of the router is through the VPN. When I am connected to VPN Whatismyip.com shows my public IP as the public IP of the VPN server. Most of the time I am away from my home lan and need to access my file server by using ssh. With the VPN running I am unable to get routed into my lan since my public IP is that of the VPN server and I can't change any of the routing on the VPN server.
Question:
With the VPN connected is there anyway for me to use my ISP public IP to ssh into my local lan? Is this even possible? Any suggestions? (I am a newbie when it comes to routing, subnets, firewalls, etc.)
Supporting Info:
eth1 = WAN port, tun0 = VPN, br-lan = 4 port switch on router (VLAN)
Route table with VPN connected:
Route table with VPN disconnected:
My router is 10.10.10.1 with DHCP dishing out 10.10.10.2-20
I am using openVPN 2.2.1 (complied for MIPS) and the server is sending this PUSH command to setup the routing:
