Filter possibilities Bridge mode: Broadcast, multicast, destination MAC address,
source MAC address, automatic filtering of local and
remote stations
IP router TCP, UDP port filtering, source and destination net-
work filter
IP masquerading
(NAT/PAT) Internet access using a single IP address via IP address and port implementation, static/
dynamic IP address assignment via DHCP, masking of TCP, UDP, ICMP and FTP; DNS forward-
ing; inverse masquerading for intranet IP services
Management Cable network operator: Via SNMP and TFTP (transfer of configuration files and
firmware updates)
User: Via the cable TV network or LAN with TCP/IP, pass-
word protection,
ELSA LANconfig , SNMP, TFTP, telnet
