Routing all traffic through PPTP: "RTNETLINK answers: File exists"

JJJollyjim · 2014-01-18 08:19:01

Following the instructions on the wiki, I've set up a PPTP connection (shows in "ip addr show", no error message with the verbose options given).

I'd like to route all traffic through the proxy:

sudo ip route add default dev ppp0

Unfortunately the above command responds with:

RTNETLINK answers: File exists

And doesn't affect network traffic. Any ideas on getting this working? Thanks!

It means you already have default route added on that interface, you cannot have two. Use either:

ip route replace default dev ppp0

or

ip route flush dev ppp0
ip route add default dev ppp0

Thanks for that, it works great.
