We are setting up our first ngfw and running into a problem that is probably simple. We are new to the barracuda firewall and still learning the ins and outs. I am trying to create a route to our server network but it appears to be conflicting with the mgmt ip address.
We get an error that says "pending gateway route 192-Servers with target "192.168.0.0/20" generates duplicate route".
Our current setup-
internal ip 10.254.254.57/30 <----ngfw---> external isp ip -- x.x.x.x/30.
Route to get to our internal user networks 10.0.0.0/8 via 10.254.254.57. Works fine.
ngfw physical mgmt interface has an ip address in our server vlan 192.168.2.202/20.
The problem occurs when I try to setup a route to get to our server networks 192.168.0.0/20 via 10.254.254.57.
I understand the why but i'm not sure how to fix it.
Any advice would be greatly appreciated.
