I have one CentOS VM installed on local VMWare player with NAT. The IP address is "192.168.126.128" and host computer IP address is "192.168.126.1". I can reach it and work on it. But when I connect to company's VPN with cisco anyconnect, I immediately lose the connection to the VM.

I compared the route. Before VPN, there is a route:

    **192.168.126.0    255.255.255.0         On-link          10.0.0.3     11**
  192.168.126.255  255.255.255.255         On-link          10.0.0.3    266

But it disappeared when I connect VPN with cisco anyconnect. Manually add with 'route -p add' doesn't work. It worked before but after a VPN update it doesn't work now. Can you please kindly share your experience about this? Thanks

I had to change the subnet to a subnet not covered by VPN route list to fix this issue. I found it is not easy to change it. I had to install workstation and use the vmnetcfg.exe to update the configuration first(then remove).
