a. the branch office needs to configured as a split tunnel to allow local connectivity and internet connectivity
b. the branch office needs to be configured to send all traffic down the vpn tunnel and the main office needs to route the traffic back that needs local connectivity… i. e. the branch’s local printers and servers
c. the branch office needs to route local ip traffic locally, directly route internet traffic to the internet and not down the vpn tunnel, and route the main office’s traffic down the vpn tunnel
d. the branch offices router needs to have the routes configured to send all ip traffic destined to the main office’s networks and the internet down the vpn tunnel and route all other local traffic normally
