4301.0. "Pathworks Alias over WAN" by NNTPD::"[email protected]" (Luraschi Carlo) Mon May 26 1997 04:30

Hello,
   I have a Pathworks customer who uses the Pathworks Alias and
TCP/IP as their protocol.
   Is possible to use Pathworks Alias over different subnet ?
   Is documented somewhere that Pathworks Alias is supported in a
WAN enviroment or only in a LAN ?

   Thanks
        Carlo Luraschi

4301.1NETBIOS is LAN-only (but...)VMSNET::P_NUNEZTue May 27 1997 10:3025
    Carlo,
    
    The PATHWORKS cluster alias is a NetBIOS name, so it's subject to the
    usual rules regarding NetBIOS broadcasts - they normally can't pass
    thru a router.  But there are workarounds:
    
    1.  Some CISCO (maybe others?) routers allow you to let packets
    addressed to udp ports 137, 138, and 139 pass thru.  These 3 ports are
    used for netbios broadcast services, netbios datagram services, and
    netbios session services, respectively. So as far as NETBIOS
    applications are concerned, it's one big LAN.
    
    2.  The UCX 4.X METRIC server (special DNS functionality) can be used
    by clients which support netbios name resolution using DNS to provide
    the same capabilities as the PATHWORKS cluster alias (basically, both
    the PATHWORKS cluster alias and UCX metric server use the same name;
    clients on remote lans query the DNS server for the name and get the IP
    address of the least loaded UCX node in the cluster; so you're not
    really using the PATHWORKS cluster alias, but are achieving the same
    results).
