Visitor internetwork access
YesWare visitors receive access to the Internet or other internetwork through
YesWare’s InterProxy capability. The InterProxy function is unique in that it
accepts traffic from TCP/IP clients regardless of a client’s IP address
configuration.The following sections describe visitor internetwork access
using the InterProxy module, and the requirements visitor computers must
meet to receive InterProxy-based internetwork access.
InterProxy-based internetwork access
The InterProxy is a specialized network address translator that enables
YesWare visitors with non-local IP addresses to access the Internet or
company intranet without re-configuring any IP settings. One YWS unit can
connect hundreds of random/non-local visitors to the router/gateway of either
an Internet Service Provider (ISP) or the company intranet.
Visitors receiving InterProxy-based internetwork access complete the
following process:
1 The visitor connects to the YesWare VBN through either an EtherLoop
modem or Ethernet switch port, starts the visitor computer and attempts to
browse the Internet.
Note: If the port is configured with one of the billing methods used in
Enhanced Modem Billing or Ethernet Port Billing, the visitor must provide
the required authentication information at this point.
2 The EtherLoop or Ethernet system connects over an intermediate switch or
hub to the YWS ETH 1 interface.
3 At the YWS, the InterProxy module translates non-local visitor IP
addresses to appear local to the host network, and routes the VBN traffic
from the ETH 1 interface over to the ETH 0 interface.
4 The ETH 0 interface connects to the host LAN or LAN/WAN termination
which is connected to a WAN such as the Internet or a corporate intranet.
InterProxy-based limitations for visitor computers
InterProxy-based internetwork access has the following limitations:
• Visitors who have assigned IP addresses that are in the same subnet as the
ETH 0 IP address will not receive internetwork access (with the exception
of IP addresses provisioned using the Conference Scheduler module).
• Visitors that have a home page designated with the "don’t use proxies"
feature enabled for the home page will not receive internetwork access.
Figure 1-2 on page 1-7 illustrates how the YesWare VBN enables InterProxy-
based internetwork access and completes this process.
