By selecting ADVANCED, you can enter a page to set:
• The range of dynamic TCP and UDP ports (*).
• The quality of service policy to be applied:
IP Precedence/TOS
Differentiated service. You can choose audio and video values in a 0 to 63 range
• “Use NAT”:
1. “NAT Type”should be set to “Others”
2. “Public IP address” must be the public IP address of the NAT.
By selecting the “BANDWIDTH” icon is possible to enable and set maximum bandwidth usage
limits (in Kbps). These limits can be different in transmission and reception, a very useful function
on ADSL networks.
Firewalls
All Aethra videoconference systems have been tested with:
Cisco PIX Firewall (Firewall H.323 compatible - release 6.1 or later).
Cisco MCM Proxy (NAT H.323 compatible - IOS release 12.2 or later).
Note (*) :
when a firewall is crossed, the firewall administrator must open a range of dynamic TCP and UDP ports, as
configured in the system, to allow bidirectional IP traffic. Moreover, once the ports have been opened, the
protocols (TCP 1720 (Q.931), TCP 1503 (T.120), UDP 1719, and 1718 (RAS)) involved in a call must be taken
into account.
