kvpnc PPTP issue

Hi there,
i tried to connect to the VPN network at my university but it does not work. It works well with windows.

I use kvpnc, I have installed pptpclient, I have the ppp-mppe module loaded. In theory I am connetced (I input my username and password) but I can only ping my pptp server (10.13.1.1), when I try to ping some server outside the network I get no response. What could be the problem?

regards,
mdv

Re: kvpnc PPTP issue

I found out that when I do

ping -I ppp0 213.73.5.100

I get a response, but when I do not use the -I option I do not. So it seems that I have internet connection but only at the ppp0 interface, and no application uses it. How could I force my apps to use ppp0?

Re: kvpnc PPTP issue

Probably the routing table is still set for your normal network connection.

execute route to get the current table.

It should look similar to this :

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
10.0.0.0        *               255.255.255.0   U     0      0        0 eth0
default         SpeedTouch.lan  0.0.0.0         UG    0      0        0 eth0

Look in kvpnc settings for an option to overwrite the existing default gateway.
If you can't find one, try this to set the ppp0 interface as default gateway :

route add default gw ppp0

NOTE : make sure to write down your original default line just in case.

Re: kvpnc PPTP issue

Thank you, it worked. I used

# route add default dev ppp0

. You need to provide an IP addres after gw, so it is correct to use dev.

yep, makes sense.
at first i wanted to put the ip-address 10.13.1.1 (your pptp server) in that line, realised i didn't know if ping reached that through ppp0 and put that instead.
I forgot to check if "gw" accepted devices also.

Glad you found the correct answer.
