- you think. (Also an inexpensive version is available from a real company
- with support and all that stuff).

- FROM THE BROCHURE:
-
- The OSU KarlBridge is a full featured protocol filtering bridge for Ethernet.
- It has the most extensive filtering capability of any bridge or router
- available. It will filter packets by any Ethernet protocol or Ethernet
- address and also IP Socket (incomming and/or outgoing), IP address, IP Subnet,
- AppleTalk Server Name, AppleTalk Zone Name, DECnet Object and DECnet address.
-
- Features:
- 1) Ping'able with SNMP support for MIB-II, Ethernet-like Interface MIB,
- and Bridge MIB.
- 2) Can be configured to filter specific packets by protocol, address
- server name and zone name by the use of easy to understand menus.
- 3) Provides protection against erroneous Ethernet packets, that a
- standard bridge does not provide.
- 4) Leaks are greatly reduced compared to standard bridges, due to
- unique filtering and timed-learning algorithms.
- 5) Works on any Thin or Thick Ethernet with 10BASE-T optional.
- 6) Very good packet forwarding rate; 8100 packets per second.
- (If you choose to use your own clone this may vary)
- 7) Excellent packet forwarding delay; 140 uS (for small packets)
- (If you choose to use your own clone this may vary)
- 8) Easily upgraded, since the code and filters are on standard PC
- compatible bootable floppy.
