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.

The firewall will not allow duplicate routes. You can change the existing managment network to match the /20 netmask (but you must plug in to the port the MGMT IP is on - usually p1 or MGMT) or change the Management IP to be in a different unused subnet.  You alw

I can also highly recommend doing the first couple of modules of the CloudGen Firewall Foundation training videos (they are free). That will save you a lot of time and frustration when configuring the firewall for the first time:
