I've recently configured an old laptop to sit on my home network, and I have it sending all of its traffic through an OpenVPN connection. It's running Ubuntu 14.04. I'm still able to connect to this laptop from other computers on the LAN via SSH and web browsers.
Now, I've also set up my wireless router to run a PPTP VPN server, so that I can connect to my home network from work (with a MacBook). When I do that, however, I'm able to see the other computers on the LAN, but not the VPN'd laptop.
I'm assuming that when I'm connected through the VPN server, my traffic to the laptop is being routed through the wrong interface, but my networking-fu isn't strong enough to know where or how to fix this. Any thoughts?
Some information about my setup:
- Router: ASUS RT-N66U with merlin firmware (192.168.1.1)
- LAN DHCP pool: 192.168.1.2-254
- Router VPN server client pool: 192.168.10.2-11
- VPN laptop (192.168.1.20)
