Please find the diagram below.
Look like this is your design. May I know how you want the clients at both sites to access internet? Clients access internet via their nearest WAN link respectively? If this is what you want, below is the steps. Please take note, the client at Remote Office has to use static IP. This is to avoid 2 DHCP servers in network 192.168.1.x and clients on both side pointing to the correct gateway.
