Procedure 13-1
Adding or removing modem privacy filters
Access this function by selecting Port Manager / EtherLoop Modem
Provisioning / Add privacy filters.
Feature description
By default, EtherLoop modems in a YesWare VBN function as an unprotected
LAN. That is, every computer connected can "see" every other computer on
the YesWare VBN, as long as one visitor knows the other visitor’s IP address
(which is not difficult with the variety of IP "sniffer" products available).
EtherLoop MAC filters prevent or allow communications based on the MAC
addresses provisioned in a modem’s filter table. If no MAC filters are in a
modem’s filter table, all computers connected to the VBN have potential
access to that computer. The Add Privacy filters function has the following
important uses:
• First, by entering the MAC address of only the YWS ETH 1 in the filter
tables of a selected group of modems (or of all CPE modems in the
database), the selected modems will only accept traffic from the YWS.
This provides a secure environment that prevents unauthorized access to
visitor computers.
• Second, by adding a group of CPE modem MAC addresses to the filter
tables for a small group of modems (less than eight), the YesWare
administrator can set up workgroups in which only users from the same
workgroup can access other workgroup computers.
