I have tired this way,
current net work 192.168.16.0/24
with this netowkr the internet is connected. Once i connected i lost all LAN. i added the second NIC with different netowrk(10.0.0.0) connected to interent.. so i can access my lan.
i read in cisco website , if we enable split tunneling this problem can be solved. Is it secured that enabling split tunneling?

Thanks
