IP Configuration (Integrated LAN)
In this menu, you can enable/disable automatic assignment of an IP address:
• IP address;
• Subnet mask;
• Gateway IP address;
• DNS server IP address.
Is possible to configure Ethernet port either for what concerns connection LAN speed
(10Mbps / 100Mbps), or Duplex Mode (Half / Full), in order to optimally operate with
HUB/Switch that do not support automatic configuration.
Default configuration is <Auto> for both settings.

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.
