can't ping utun0 ip:

when connect vpn server windows using cisco vpn client works fine.

might problem?

 

i notice local subnet (192.168.1.x) conflicts entry on vpn. i'm surprised vpn provider tunnelling both 172.16 , 192.168 networks.

option, appears, use 10.x.y.z subnet doesn't conflict, such 10.200.1.x.
