The protocol will function with-
■
out TCP/UDP port numbers, e.g.
ICMP or IGMP.
The OpenCom 100 NAT has suitable
processes for ensuring the functions
of many important protocols af-
fected by these rules. These are the
protocols FTP (in "active" mode), Cu-
SeeMe ("videoconferencing"), IRC
("chat"), ICMP errors ("traceroute")
and ICMP echo ("ping").
Protocols which require inward-di-
rected connection establishment
can be configured in the Net Config-
uration: Port Access menu. For fur-
ther information, refer to the online
help of this menu.
