Subnets always work in powers of two. Since you have a /26 (62 addresses), the largest subnet you can make of that is a /27 (30 addresses). The traditional way to get the unequal division you want is to put the /26 on the `inside' interface and put, say, a /29 (6 addresses) taken out of that /26 on the `outside' interface. On this host the more specific /29 route will override the less specific /26 for the hosts on the /29. Then you proxy-arp on the /26 interface the hosts that are really on /29, so that the folks on /26 believe that these machines on the /29 are on the same network as they are. cjs Curt Sampson cjs@portal.ca Info at http://www.portal.ca/ Internet Portal Services, Inc.
