The below is actually public addess space, just using 10 for clarity's sake: Default Gateway: 10.8.16.1 The provider has given me the following information (changed to private IP space for security reasons): Default Gateway: 10.8.16.1 My IP's: 10.8.23.121 - 126 Subnet Block: 10.8.23.120/29 This works 100% on a windows machine but does not work at all on any unix machines. When my Windows 2000 box is plugged in I get the following: C:\>arp -a Interface: 195.8.23.121 on Interface 0x1000003 Internet Address Physical Address Type 10.8.16.1 00-03-40-9c-0a-99 dynamic C:\>netstat -nr Route Table ================================================================ Interface List 0x1 ...........................

Is this happening because on Proxy ARP? Even though this is wrong it must be possible? :>) While I know that this is not solving the cause of the problem it will take me a while to both convince this isp to let me help & to solve their routing problems. Please send replies to me directly as I don't have the time to keep up to date with all list mail atm. Any help would be most appreciated.
