ANSWERED OpenVPN & Linux (Mint)

[razevpn 0]

Hello,

I have a newbie question..

When using AirVPN via OpenVPN in Linux, does "ALL" traffic, including Transmission go through the VPN tunnel?  I suspect that the answer is yes; however, I need to explain why the question.

I have an ASUS RT-N16 router running OpenWRT.  The best speeds I get from that box is 800kBps (or 7.5Mbps speedtest) whereas it is beyond 3MBps (or 100Mbps speedtest) using a Linux machine running OpenVPN on the same server.  My concern is that there is an issue with one of the methods.  From what I read, the ASUS routers have not been getting favorable reviews due to performance.  I simply want to make sure that the OpenVPN in Linux also covers all traffic, including Transmission.

Of course yes, and this on all platforms. But if you want a verification, enter these into a terminal while connected and post their output here:

$ ip -4 r
$ ip -6 r

With 100 Mbit/s you should be downloading with more than 10 MB/s. Can you try a well seeded torrent like Ubuntu and see what throughput you get out of it? Not when connected with the router, of course.

Line 1 is a default route via VPN (interface tun0) with a lower metric, therefore higher priority, than the other default route via your router in line 2 (50 vs. 100). This gives the VPN route priority. Therefore I can confirm that everything is routed through the VPN server. The only exceptions are line 4, the VPN server's IP, and line 6 which is your local network.

IPv6 routes are negligible here; you don't seem to have IPv6 connectivity in your network.
