Alias IP is not supported on a bridge interface. You can only assign an alias IP to a separate
network LAN or switch. If you remove or disable the LAN, any assigned alias IPs are also
removed.
When you edit an alias IP, you cannot change the port or the ID.
To create an Alias IP on WAN, you must create an additional internet connection on the same
WAN interface. See
"Configuring Internet Connectivity" on page107

VPN Tunnel (VTI)
To create/edit a VPN Tunnel (VTI):
A Virtual Tunnel Interface (VTI) is a virtual interface on a Security Gateway that is related to an
existing, Route Based VPN tunnel. The Route Based VPN tunnel works as a point-to-point
connection between two peer Security Gateways in a VPN community. Each peer Security
Gateway has one VTI that connects to the tunnel.
The VPN tunnel and its properties are defined by the VPN community that contains the two
gateways. You must define the VPN community and its member Security Gateways before
you can create a VTI.
Configure the fields in the tabs:
The 'Configuration' tab

Remote IP address - The IP address to be used at the peer gateway's point-to-
point virtual interface.
n
Unnumbered VTI - When the VTI is unnumbered, it is not necessary to configure local

for outbound traffic.
