I have a cisco router and I use it for internet and VPN
currently I have a internet access, but I don't have the VPN connection, I applied the correct configuration for the VPN.
the most important point in your configuration is to check the VPN result.
did you checked your router and along with VPN connection? you can use below commands to check the status of the PVN:
show crypto isakmp sa
show crypto ipsec sa
show crypto session
show crypto isakmp peer
also you can use debug commands
