"
For network protocols that an IP router is configured
to bridge. Many routers may be installed to bridge
specific frame types. These routers are often referred
to as B-routers.
"
For network protocols a router is capable of routing.
For example, IPX frames should not be tunneled
through a router capable of routing both IP and IPX
frames.
If access points are installed so that a wireless secondary
LAN can be established between access points separated by
a router, it is possible to inadvertently bridge around the
router. This can be avoided by choosing designated bridge
locations, or choosing radio channels to avoid inadvertent
wireless bridging.
OWL/IP Safeguards
The purpose of a router is to segment traffic on a local
network, and selectively forward frames destined to
addresses on other networks. OWL/IP is designed to
minimize the impact on existing installations, while
supporting mobility for wireless stations. The safeguards
on the following pages are built into OWL/IP.
Default Settings
By default, OWL/IP is disabled and must be manually
enabled before tunnels are originated. Additionally, once
enabled, default filter settings prevent forwarding of all
protocols except NORAND Network Layer (NNL), ARP for
IP address resolution, and ICMP, which supports diagnostic
capabilities such as PING. Extensive filtering capabilities
are provided to allow traffic to be restricted to that known
to be destined to wireless stations.
