The following illustration shows how a service provider might provide H.460
firewall traversal between two enterprise locations. In this example the
Polycom Video Border Proxy™ (VBP
®
) firewall traversal device is on the edge
of the service provider network and facilitates IP calls between Polycom HDX
systems behind different firewalls.
To use this traversal, Polycom HDX systems and firewalls must be configured
as follows:
1 Enable firewall traversal on the Polycom HDX system.
a Go to System > Admin Settings > Network > IP > Firewall.
b Select Enable H.460 Firewall Traversal.
2 Register the Polycom HDX system to an external Polycom VBP device
that supports the H.460.18 and H.460.19 standards.
3 Make sure that firewalls being traversed allow Polycom HDX systems
behind them to open outbound TCP and UDP connections.
— Firewalls with a stricter rule set should allow Polycom HDX systems
to open at least the following outbound TCP and UDP ports: 1720
(TCP), 14085-15084 (TCP) and 1719 (UDP), 16386-25386 (UDP).
— Firewalls should permit inbound traffic to TCP and UDP ports that
have been opened earlier in the outbound direction.
Basic Firewall/NAT Traversal Connectivity
Basic Firewall/NAT Traversal Connectivity allows HDX systems to connect to
the SIP-based RealPresence solutions using the Acme Packet Net-Net family of
Session Border Controllers (SBC). An HDX system connects to the Acme
Packet Net-Net SBC as a remote enterprise endpoint. The remote enterprise
endpoint is registered to the enterprise’s SIP infrastructure and connects to an
internal enterprise endpoint through the enterprise firewall.
