Network Connections

If a port is experiencing difficulties auto-negotiating with another device, Ethernet speed

and duplex may be set manually by selecting Edit Ethernet configuration.

Each of the network ports that may be present on your CyberGuard SG appliance and

how they may be configured are discussed below.

Note

SG rack mount appliances (SG710, SG710+) differ slightly from other models in that any

port can be configured to perform any function.

Switch A – B, Port C – F

Note

SG rack mount appliances (SG710, SG710+) only.

CyberGuard SG rack mount appliances have generically named Ethernet ports (A, B, C,

D, E, F) as any port can be configured to perform any function (LAN, WAN, DMZ). Only

the first LAN switch (A) is special in that it is configured as a Direct LAN connection by

default.

Aside from this, network configuration options are similar to other CyberGuard SG

appliances.

Warning

We recommend leaving network switch A as a LAN connection, as this is the interface

through which the CyberGuard SG appliance will attempt to network load a recovery

firmware image in the unlikely event that it fails to boot. Recovery booting from an

untrusted network represents a security hazard.
