Ubuntu – FortiClient VPN connected but no IP

networking

I am on Ubuntu 12.04. I managed to install the FortiClient after lots of search and mainly by installing everything suggested on these pages :

Now I have it running and the connection status indicates tunnel running and I see bytes receives and send bytes.

I am trying to connect to remote desktop to a Windows 7 machine but it doesn't work. first thing first I check if I ping the machine and no it doesn't ping.

I looked under Devices – Network Tools, I can see that there was no interface created for the VPN and I don't have an IP for the tunnel. I only have my local network IP.

I tried the 2010 and 21467 versions.

Can someone help on this?

Ok I found the solution. The forticlient does not create the routes needed for the tunnel to work as expected. In a terminal type:

sudo route add -net [office lan IP] netmask 255.255.254.0 dev ppp0

eg:

sudo route add -net 192.168.38.0 netmask 255.255.254.0 dev ppp0

where 192.168.38.0/23 is my office LAN range. My office PC is on 192.168.38.83. Then when using remmina app I used my office PC IP-Address and got my remote desktop working. My Win7 office PC looks like win XP but at least I can work.

The only problem is that I have to enter this command EACH time I reconnect to the vpn through forticlient.

I added this command in a script in /etc/ppp/ip-up.d but that didn't work.

Ubuntu – forticlient vpn broke the non-vpn dns

I found out that even when not connected to the vpn, may /etc/resolf.conf contained the server address of my work (the X.X.X.X in the question). Actually it contained it twice, and when the client is connected, then there are 3 of those. I guess vpnclient happened to left those lines when some bug occurred.

So I deleted those line, to keep only:

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.1.

And it seems to work well again.

I'll correct this answer if I encounter the problem again.
