Another thing I wanted to say was the same client configuration perfectly
works when I try from
a Windows XP machine. The tunnel is always established and I do not see any
issues at all. On
both the Windows and Linux, the client version is same (2.1.7). I do not
understand what is that
Windows XP does to get the tunnel established and Linux is not doing. Please
note that firewall
has been disabled on both the machines.
