The best way that I've found to "visualise" this problem (and the solution to it) is to work along the following lines: A Class "C" Subnet maps directly to one AppleTalk (IPTalk) network, A Class B Subnet contains 254 (255? 256?) Class C Subnets, Therefore a Class B Subnet potentially contains 254 AppleTalk networks. All you have to do is to name them (i.e. allocate network numbers for each IP address that has the third octet different). After having "named" them on your whiteboard, transfer the information (the AppleTalk network number, IP subnet number and zone name) to your atalkatab file and reboot the gateways. ======================== Tom Evans tom@wcc.oz.au Webster Computer Corp P/L, 1270 Ferntree Gully Rd Scoresby, Melbourne 3179 Victoria, Australia 61-3-764-1100 FAX ...764-1179 A.C.N. 004 818 455 wcc@cup.portal.com, AppleLink: "WEBSTER.USA" 2109 O'Toole Avenue, Suite J SAN JOSE CA 95131 - 1303 CALIFORNIA 1-408-954-8054 FAX 1-408-954-1832 AppleLink WEBSTER.USA
