I set up a vpn using these instructions. For over a year it worked fine. All of the traffic through my router was sent over the vpn to the internet. Recently, it stopped working completely. The connection to openvpn is active, but I have no access to the internet through the vpn. If I disable the vpn, I have an internet connection again. I can't figure out what changed to make it stop working. I have tried three different routers and I also set up another VPS with Openvpn installed, but I get the same result. I have made sure that TUN/TAP is enabled on my VPS.
Actually, as soon as I enable the VPN, I can check http://whatismyipaddress.com/ really quickly before my internet cuts out. It confirms that my ip is that of my VPS.
Here is another strange thing. When I put an ip address of a computer on my network into "Policy Based Routing," my whole network has internet access again including the computer whose ip I listed. However, none of the traffic is routed through the VPN.
The trace completed with no problem. It was just really slow.
I found that I can access the internet, but I have extremely low bandwidth. I can use telnet. And I can pull up simple web pages like the "It works!" page from apache. I can also load Google's home page but it takes about two minutes.
I found another strange thing. While DD-WRT was connected to the VPN, I also connected using the OpenVPN Connect software on my computer and I had full bandwidth.
