| 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).
HTH,
Paul
