If the network specification for an external network changes, you can modify its network settings.
- Click the Manage & Monitor tab and click External Networks in the left pane.
- Right-click the external network name and select Properties.
- On the Network Specification tab, select the external network specification to modify, and click Modify.
- Modify the settings as necessary and click OK.
You cannot modify the network mask or default gateway. If you need an external network with a different netmask or gateway, create one.
