HP Velocity group policy About the HP Velocity Administrative Template

Special TCP Ports 554 1720 5060 1723 Special Port Filter for TCP and UDP:

The special port filter allows administrators to

enable or disable support for specific protocols.

By default, the special port filter is pre-

configured to include ports that provide special

protocol support, such as RTSP (554), H.323

(1720), PPTP (1723), and SIP (5060).

To disable support for a specific protocol,

remove the corresponding port from the filter.

For example, to disable support for RTSP,

remove port 554 from the special TCP and UDP

port filters.

Special UDP Ports 554 5060

Whitelist TCP Ports Whitelist filter for TCP and UDP:

If a whitelist port filter is specified, only the traffic

meeting the following criteria is protected by

HP Velocity:

• The destination IP address for the traffic is not

specified in the blacklist IP filter.

• The destination IP address for the traffic is

specified in the whitelist IP filter.

• The destination port for the traffic is specified

in the whitelist port filter.

All traffic not meeting these criteria will be

passed through transparently.

Filter

255.255.255.255/32 Blacklist IP filter:

The first IP filter to be evaluated is the blacklist

filter, which allows administrators to specify the

destination IP addresses where traffic will not

be protected by HP Velocity. If an IP address of

a specified destination matches an IP address

specified in the blacklist, it will be passed on

transparently. Administrators can use a blacklist

in conjunction with a whitelist. For example, use

the blacklist to exclude specific IP addresses in

a whitelisted subnet from being protected by

HP Velocity.
