Commit Fail After Adding Default Route to a DHCP Interface

Symptoms

After connecting the firewall to a modem that provides an IP address through DHCP and creating a default route that points to the modem, the commit fails.

Issue

By default, when configuring an interface to get an IP address from a DHCP server, the option to automatically create a default is enabled by default.

Manually adding a new static route will cause the commit to fail because there can only be one default route.

Resolution

To fix this issue, either

• Remove the static route and leave the option to automatically add a default route enabled
• Disable the option to create a default route automatically and create a manual default route.
