101
The OpenCom 100 NAT has suitable processes for ensuring the functions of many
important protocols affected by these rules. These are the protocols FTP (in
“active” mode), CuSeeMe (“videoconferencing”), IRC (“chat”), ICMP errors
(“traceroute”) and ICMP echo (“ping”).
Depending on the internet telephony protocol (VoIP, SIP) the required NAT
extension (“Full Cone NAT”) or RTP-Proxy is activated on the Media Gateway Card.
Protocols which require inward-directed connection establishment can be con-
figured in the Network: Port Access menu. For further information, refer to the
online help of this menu.
