Remote LAN Access problem over VPN

By aw_willis ·
I have established a VPN connection between two sites both with Cisco routers. I have 2 networks (192.168.1.0/24 and 10.10.35.0/24 ) on my side and I want the remote users to be able to access them both. I have one FE interface on my router and I configured it with 2 IPs; one IP from each network. The remote LAN is 192.168.100.0/24.
The tunnel is up but the remote LAN cannot access my LAN and vice-versa. what seems to be the problem here?
Someone please help me out.

remote clients have to get an address on the local lan to access resources. for Cisco, that would be an IP helper address. For Windows as the remote access server, that's a DHCP relay.

where is the connection made? how are remote users going to get a local address? who issues them a local address? does the who, who issues local address, have addresses to issue?
