The undercloud_public_vip in undercloud.conf is used to determine which
IP to use to host the GUI. If you have already set up an IP on the
External network on the Undercloud, you can use that IP.

For instance, if you have VLAN 10 that is used for the External
network, you can add it to the undercloud as an interface or VLAN, use
that IP for the undercloud_public_vip, then the undercloud web UI can
be accessed at that IP.

Note that the IP must already exist on the host before running
"openstack undercloud install".

You also may run into an issue where the UI is only accessible from the
local External network, but not from remote subnets at the same
address. This will occur if the External interface on the Undercloud is
not the interface where the default route is set. You can either set
the default route via the External network, or you can relax the
rp_filter settings in the sysctl settings to allow the system to
respond to non-local IPs that don't have a return route via the
External network.
