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.

By selecting the "BANDWIDTH" icon is possible to enable and set maximum bandwidth usage limits

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.
