The firewall comes preconfigured with a default virtual wire interface between
ports Ethernet 1/1 and Ethernet 1/2 (and a corresponding default security policy
and virtual router). If you do not plan to use the default virtual wire, you
must manually delete the configuration and commit the change before proceeding
to prevent it from interfering with other settings you define. For instructions
on how to delete the default virtual wire and its associated security policy and
zones, see Step 3 in
Set Up Network Access for External Services.
