Some time ago I asked for help on routing Appletalk and IPX packets
through a SUN gateway, several people replied, thank you all.
KarlBridge seems to be the solution in our situation. What I am
thinking now is to use the ENET driver in the CAP package to write a
small daemon to forward the packets across the interfaces; if anyone
has done the similar thing already, please let us know.

Thanks again and Happy Holidays to all!

I have used pcbridge ( if you really need routing then this is not a solution
for you ). I also made a little experiment with a software called KarlBridge.
Below is the saved article about KarlBridge.
-------------------------------------------
Folks,  I have recently released for annonymous ftp an IP, DECNET, AppleTalk,
etc firwall.  It is in the form a bridge similar to PCBRIDGE called
KarlBridge.  If you get a chance please pick it up and let me know what
you think.  (Also an inexpensive version is available from a real company
with support and all that stuff).

OSU KarlBridge can be found on: nisca.acs.ohio-state.edu (128.146.1.7)
 /pub/kbridge

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.

Any questions....  Send e-mail to kbridge@osu.edu

In addition to either pcbridge or KralBridge you need a cheap AT clone and
16-bit ethernet cards. I have used pcbridge in 12 Mhz 286 ( Wyse AT )
and 16 MHz AT ( Express AT ) and it works ok. Performance is great.
Ftp transfer rate can be over 1 Mb between two Sun SPARC over the pcbridge in
quiet network.
With KarlBridge you could let Sun do IP routing and bridge IPX and EtherTalk
with KarlBridge. I have also seen some News articles about brouter, which
is some kind of combined IP-router and bridge, but i haven't ever tried it.

Hello,
 I will try to suggest a possibble, though not public domain, solution.

You could handle that by using NetWare.
To connect MS-DOS Clients from an IP-Subnet - through IP-Routing - to a
NetWare Server in a different IP-Subnet one can use Novell's IP-Tunnel
concept. That way, on each of those DOS-Clients, Novells DOS-IP-Tunnel
must be loaden. Pity, a comparable thing does not exist for Macs, as far 
as I know.
There is another possibility that works for both DOS-Clients and MACs 
(and all other NetWare services and serviced clients): you need a NetWare 
Server in each IP-Subnet, and build an IP-Tunnel between those servers.
Clients need only attach to their nearest server, and that server then
tunnels requests to the other server(s) into IP-Packets routed via the
IP-Router.

Fort more info ask your local Novell reseller.

Do you have a brochure on the KarlBridge and if not we can send you one.

Please reply with your U.S. Mail address and we can send you the literature.

Thanks,  Doug Karl

Subject: help on routing Appletalk and IPX packets through a SUN gateway

   Greetings,

       We have some IBM PCs and Macs sitting behind a gateway (SUN 670MP
   running SunOS 4.1.2, with 2 network interfaces).  We are looking for
   some software or hardware that we can install on the gateway to enable
   the Macs (with Ethernet cards, running AppleTalk Phase II) access the
   printers and AppleShare volumes, and the PCs (with Novell ne1000 cards)
   talk to the NetWare file servers on the outside of the gateway?
       Thanks.


You could use CAP with UAB (unix apple talk bridge) if it were Phase I.

You should be able to use netware for the sun to do the novell stuff.

You could get a bridge, configure it to ignore IP and place it in parallel
with your sun.  I looked at PCbridge (which converts a PC into a bridge) with
the idea of doing this but never got around to it (you need to recompile PC
bridge after putting your own filtering code into it).  I believe that there
are commercial bridges that would allow you to just specify that you wanted IP
filtered.

If you have a Novel server then you should be able to put another ethernet
card in it and get it to do what you want, again by placing it in parallel
with the PC.  I understand that you can the use the AppleShare NLM to bridge
(route?) the appletalk. (but I am not a Novel expert).

For the AppleTalk part you can run either ATIR (AppleTalk Internet
Router) or UAR (UNIX AppleTalk Router) on your SUN, as an user process,
to route the AppleTalk traffic between the two Ethernets.

For the IPX part, you can use Novell's IPTUNNEL scheme to encapsulate
IPX traffic inside IP and get it through your IP router (SUN).
