Shared gateways
allow multiple virtual systems to
share a single interface for external communication (typically connected
to a common upstream network such as an Internet Service Provider).
All of the virtual systems communicate with the outside world through
the physical interface using a single IP address. A single virtual
router is used to route traffic for all of the virtual systems through
the shared gateway.

Shared gateways use Layer 3 interfaces, and at least one Layer
3 interface must be configured as a shared gateway. Communications
originating in a virtual system and exiting the firewall through
a shared gateway require similar policy to communications passing
between two virtual systems. You could configure an ‘External vsys’
zone to define security rules in the virtual system.
Shared Gateway Settings | Description |
---|---|
ID | Identifier for the gateway (not used by
firewall). |
Name | Enter a name for the shared gateway (up
to 31 characters). The name is case-sensitive and must be unique.
Use only letters, numbers, spaces, hyphens, and underscores. Only
the name is required. |
DNS Proxy | ( Optional ) If a DNS proxy is configured,
select which DNS server(s) to use for domain name queries. |
Interfaces | Select the interfaces the shared gateway
will use. |
