Hello Sir,
As i'm able to understand, you are already running with Shophos UTM with one WAN & now you want to add another WAN for redundancy & fail-over which is on Huawei router over Ethernet. We will take below steps to complete it.
1. First i'll configure Router & test Internet on direct Laptop
2. Configure WAN interface in Shophos UTM
3. Configure Gateway fail-over & redundancy in Shophos UTM
4. Test everything & we are done
I'm working on Shopos & Cyberoam UTM since last 5 years so i can assure you that your project would be successfully completed in stipulated time-frame.
Please contact me on below detail.
Regards,
Pankaj Kumar
