Issues Creating Tunnel Route

[jbrock]

What is the name of the domain?

None - Using tunnel as a vpn replacement

What is the error message?

Error: This route’s network is inside an existing subnet’s network at “100.96.0.0/12”. Try a different network for this route or update the conflicting subnet’s network.

What is the issue you’re encountering

Unable to create a route assigned to a unique virtual network for the defined subnet 100.100.0.0/24

What steps have you taken to resolve the issue?

Created a new tunnel, new virtual networks, same issue remains. This is one of multiple tunnels (each with their own virtual network) that already have this subnet configured with no issues. I haven’t made any changes that should have caused this and have never used the ip range 100.96.0.0/12 for anything. Split tunneling is enabled for 100.100.0.0/24.

What are the steps to reproduce the issue?

Attempt to create a route for a tunnel with the IP range 100.100.0.0/24

Something has definitely changed in a recent update to zero trust because I have 5+ other routes on this ip range on separate tunnels with no issues - I just can’t create a new one… Even when I go into an existing route set to this subnet and click save I get an error (even though I changed nothing)
