As you can see I configured SITE A and can easily access SITE B over an ADSL connection. The teleworker at SITE B is situated in a different geographical location and is obtaining the IP from the router at SITE A.
My query is this: How can I configure SITE C to connect to SITE A and subsequently to SITE B without changing the IP schemas of both sites?. I know I should insert a router between the modem and the network switch in SITE C and setup NAT? Your help is greatly appreciated!
