           Add Security and Cleanup your network
             by blocking those unwanted packets
                           with
                    The OSU KarlBridge
                       Version 1.33
        (now with full SNMP support and more filters)
The OSU KarlBridge is a program, that runs on a  286 or 386 clone.
It provides a unique and inexpensive  Ethernet to  Ethernet bridge
that performs sophisticated protocol filtering.  The bridge can be
configured to filter packets based upon ANY Ethernet protocol such
as IP, IPX, DECNET, AppleTalk, and etc. In addition it will filter
packets based upon  IP address, IP network, IP subnet, and socket.
It will also  filter  packets  based upon  DECNET  address,  area,
Object number and Object name.  Also,  AppleTalk  packets  can be
filtered based upon server name,  printer name,  and/or zone name.
Some Examples:
  You can use  OSU KarlBridge as a standard medium performance MAC
  layer  Ethernet to Ethernet bridge with SNMP  (MIB II, EtherMIB,
  BridgeMIB & SNMP MIB).  You can assemble your own  IBM cloan and
  use the free software or  buy the  inexpensive pre-assembled and
  tested commercial version.
  You can configure  OSU KarlBridge  to restrict  IP  traffic from
  your public computer labs or  dial-in-lines to  IP addresses and
  subnets within your campus or enterprise wide network. This will
  prohibit  unauthenticated access to the your machines and/or the
  Internet in conformance with RFC 1173).
  You can  configure  OSU KarlBridge  to  keep  file  servers  and
  printers (Apple, Novell, Banyan, LanManager, etc.)  on  the same
  network from interacting with each other in undesirable ways.
Join thousands of people worldwide who are using the KarlBridge to
relieve some of their networking headaches. The  OSU KarlBridge is
the most flexible and easily configured bridge you have ever seen!
Get a copy, read the README file, run the configuration program on
your favorite PC, and let me know what you think.
The OSU KarlBridge can be obtained via anonymous ftp from:
    nisca.acs.ohio-state.edu, 128.146.1.7, in /pub/kbridge.
