[vpn-help] Bug report: same subnet both ends of the tunnel doesn't work.

[Ian Fraser]

Hi, I have a problem with the Shrew Soft Windows VPN client and would like to submit the following bug report:

Problem:
Recently changed from Junipers VPN client to Shrew Soft's VPN client for windows. I happily completed all testing without a problem. After the users switched some of them complained of various behaviour such as:
Connects RDP client for a short while(10-20 mins) then disconnects and refuses to reconnect.
Tunnel comes up, until try they to connect the RDP client, then the tunnel drops.
Tunnel comes up, but RDP client fails to connect.

After some time, it emerged that the users experiencing these problems were using home connections that used the same subnet range as our internal network (192.168.1.0/24 for example). I am hoping that because other VPN client software can cope with this situation, this is not an insurmountable problem.

VPN Client Version : 2.1.5-release (have also tried 2.1.6-rc-1) Windows OS : Windows Vista and XP Gateway Make/Model: Juniper SSG-140 Gateway OS version: 5.4


Best regards,

Ian Fraser
