I have 2 lines coming in with identical IP, Subnet, Gateway, DNS 1 2 3 across both services
If the Main (NGN) link goes down the Backup (Radio) link will take over this is done by 2 routers from our ISP.
Sonicwall NSA 2600 X1 is working
- X1 - Main (NGN) link
- X3 - Backup (Radio)
link
Now I have a problem adding X3 - Backup (Radio) link, the
subnet mask for X3 is the same as X1
Error: Index of the interface: Subnet on this interface overlaps with another interface
Who can shine a light on this?
Thanks in advance
