Incoming access – administration services
The following figure shows the incoming access configuration page:
Figure 6.1 Incoming access configuration
By default the SnapGear appliance runs a web administration server and a telnet service.
Access to these services can be restricted to specific interfaces. For example, you may
want to restrict access to the SnapGear appliance’s configuration web pages (Web
Admin) to machines on your local network. SnapGear does not recommend disallowing
all services, as this will make future configuration changes impossible unless your
SnapGear appliance is reset to the factory default settings.
You can also select the ICMP messages accepted on the Internet interface. For example,
if you disallow echo requests (the default for increased security), your SnapGear
appliance will not respond to pings on its Internet interface. Destination unreachable
ICMP messages are always accepted.
