The KarlBridge is a program, that runs on a 286 or 386 clone. It provides a unique and inexpensive 2 port Ethernet to Ethernet bridge that performs very sophisticated high level protocol filtering. The bridge filters packets based on ANY specified Ethernet protocol such as IP, XNS, DECNET, LAT, AppleTalk, NetBEUI, Novell IPX, etc. In addition it provides IP "firewall" protection by filtering IP packets based upon IP address/network/subnet combinations and socket number. It will also provide DECNET "firewall" filtering based upon DECNET address, Area, Object number and Object name. It will also filter AppleTalk Phase 1 & 2 packets based upon file server name, printer name, and/or Zone name. (Yes, Novell SAP filtering is coming in the next release, along with NCR WaveLAN support). The free version of KarlBridge is available via anonymous ftp from: 128.146.1.7 /pub/kbridge WHAT ELSE IS IT? The KarlBridge is also a complete bridge box based upon the commercial version of the KarlBridge code. It comes with AUI & 10Base2 or AUI & 10BaseT connectors. It is a very nice small box, with a 386DX40, 2 SMC Elite 16 Ethernet cards, special boot ROM, and Floppy drive or Flash ROM card. It is fully tested and burnt in for added reliability with a 1 year warranty. KarlNet Inc. is the main commercial supplier of the KarlBridge hardware and software. KarlNet Inc. sells the KarlBridge box for $1195. Look for the product review in March 1993 issue of Personal Computer magazine, pg 455, published in England, and the upcoming April 1993 issue of IEEE Computer. KarlBridges are also manufactured and sold in the UK by Sherwood Data Systems. SOME EXAMPLES: You can use KarlBridge as a standard medium to high performance MAC layer Ethernet to Ethernet bridge with SNMP (MIB II, Ether MIB, Bridge MIB & SNMP MIB). You can configure a KarlBridge to restrict traffic from your public computer labs or dial-in-lines to subnets within your campus or corporate LAN, prohibiting unauthorized access to your LAN or the Internet (in conformance with RFC 1173). You can configure a KarlBridge to pass only IP traffic and use it to replace many of the functions that people use an IP router for; such as localizing non-IP traffic to within a room or workgroup. Many folks have used this feature to bridge IP (only) between several Novell LAN's. They did not want to load down their Novell server with the burden of routing IP between interfaces. The same concept has been used to bridge NetBUEI or LAT (only) between two IP routed networks. You can configure KarlBridge to keep file and print servers (Apple, Novell, Banyan, and etc.) on the same network from interfering with each other. Join thousands of people worldwide who are using the KarlBridge to solve some of their networking nightmares. The KarlBridge is the most flexible, inexpensive 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.
