Cannot connect to the Branch Internet Router with RED Unified Mode

Hi,

After configuring standard/unified mode for a branch RED Device, I am unable to connect to the branch internet router from any branch PC. The traffic is being routed through sophos firewall. I added a route in the branch PC like below but still the same.

route add branch_router_ip mask 255.255.255.255 branch_red_device_ip

route add 192.168.8.1 mask 255.255.255.255 192.168.8.10

The RED Device IP taken from Firewall DHCP is 192.168.8.10.

Secondly, how can I access the branch internet router LAN Interface from the Head Office Network?

Thanks.
