Access of VPN Client to LAN network

We are trying to allow access to LAN network through VPN from SEP client but not successful even after disabling firewall policy. Before installing SEP client on our computers, We didnt have issue with VPN to LAN access and we were able to access resources within LAN network. With SEP installed, We are able to connect to VPN but cant access internal network. Is there a way to enable VPN access to resources within LAN network?
