It depends. Most VPN routers (wired and wireless) will support a gateway-to-gateway tunnel, i.e. you can connect your LAN to another remote LAN. You can define tunnels to multiple locations if necessary. However, all LANs - local and remote - must use unique IP subnets. You cannot connect a LAN 192.168.1.* to a remote LAN 192.168.1.* for instance.
What is not possible is to connect through the router to arbitrary remote locations to connect a single computer to the remote LAN like you can do with the VPN client.
