A problem with openconnect On Windows

[xiao]

Hello,

I compiled the  newest openconnect in git for Windows，And run it on Win 7 (in a LAN) to connect the ocserv 0.8.4 (in the public network)。
Everything is OK when connecting.

And I  can visit the internet by browser  through the VPN tunnel.

But sometimes I can't  visit the internet through the VPN tunnel,although the VPN tunnel exists well.

At this moment ,I find the route table is right. like below

But when I use the tracert tool under cmd  ,I find that the first hop is not the interface " 10.1.1.209" but  my  real public IP.

And when I wait for sometime, I use the tracert tool under cmd ,the first hop change to  the interface " 10.1.1.208" ,And at this moment I can visist the internet Again.

This Situation will Repeat.
