Out of Band Management Access issue in USG6630E

We are facing issue to connect USG6630E firewall when we are connecting through our network . when we connect it directly through laptop it works fine.

We could see the session is completed in the firewall session table. But we are unable to reach Management IP

After checking the diag file we found the following :

USG6630E uptime is 0 week, 0 day, 20 hours, 40 minutes

ip binding vpn-instance default

ip address 192.168.0.1 255.255.255.0

·       By default, the IP address of the Management Interface is 192.168.0.1. The interface has been added to the Trust zone, and the HTTP, HTTPS, and Ping permissions are enabled on the Management interface. You can access the device through the Management Interface without configuring any security policy.  .

·       VPN instance default is bound to the Management Interface by default. If the Management Interface is used to ping, STelnet, Telnet, FTP, or SFTP other PCs or devices, the vpn-instance default parameter must be specified, such as telnet vpn-instance default 10.2.2.1.

Reference Here

By default The management port is bound to VPN instance default

·      Kindly when you try to connect to management IP , specify the vpn-instance default in the command such as >> ping vpn-instance default 192.168.0.1

·      Or remove the default configuration ip binding vpn-instance default by run:

>> interface Meth0/0/0

>> undo ip binding vpn-instance default

We have done the configuration, to disable binding with defaut vpn-instance.

Now we are able to bind MGMT interface with public virtual system and access the firewall management
