Service Filtering

The Service Filtering feature lets you give certain users permission to access the X5v from outside the network—that is, over the Internet. If you enable one of the services listed on this page, the X5v’s firewall will open up the appropriate port to allow the service to work.

PING from External Network	Disabled by default. Enable it
	to allow an external user to
	ping your X5v. This can be
	useful if you need to
	troubleshoot your unit.
FTP from External Network*	Disabled by default. Enable it
	to allow an external user to ftp
	into your X5v. Typically, you
	would do this if you wanted
	someone to check the X5v’s
	configuration.
DNS from External Network	Disabled by default. Enable it
	to allow your X5v to accept
	DNS requests from an external
	source.
IKE from External Network	Disabled by default. Enable it
	to allow a VPN (virtual private
	network) connection to your
	network.
RIP from External Network	Disabled by default. Enable it
	to allow your X5v to receive
	RIP (Routing Information
	Protocol) requests from an
	external source. The Technical
	Reference Manual contains
	details about RIP; go to
	www.zoom.com
DHCP from External Network	Disabled by default. Enable it
	to allow your X5v to receive
	DHCP requests from an
	external source.

*Important: To complete the step of allowing remote users to FTP into the X5v, you must go to the X5v’s Advanced Setup
