He has given me one 10bT wire and set me up on one of his segments. He has assigned me one IP in his subnet and is routing stuff to me through that IP. I have a class C network assigned to me. I want to subdivide that Class C so that one subnet of 128 (upper 128 addresses minus whatever overhead) is at my colocation and one subnet (first 32 addresses) is at my other location over my feed. The other subnets will be assigned as needed. The 4 co-located machines are hooked to a dumb hub at the ISPs location. This hub is hooked to his hub. I have designated one of my machines to act as a router for my subnet there. What I want to do is have the main IP address (from /etc/sysconfig) set to the address in the ISPs subnet space (being routed too). I want to assign the ethernet port an alias IP address existing in my subnet. The router for this machine is assigned to be the router for the ISPs subnet. All other machines have addresses in my subnet. What I need to know is where to put the alias IP address ifconfig (adding an extra ifconfig_de0 seemed to screw up the startup) and the commands needed (including netmask) to set up routing for this machine and others in the subnet. This machine needs to route packets coming in on the ISP assigned address to machines in the subnet and also needs to take packets from them (or itself) destined for outside the subnet and route them out. The ISP assigned IP is 199.104.120.223 and the router for this network is .1 My Class C is 204.228.145.0 The subnet at the ISP is 204.228.145.upper128-addresses The subnet at my other location with a link to the ISP is 204.228.145.first32 The main machine doing the routing has the IPs 199.104.120.223 and 204.228.145.130 Please help me get the places for the various setups (sysconfig etc) and exactly what to put in there (ifconfig, route add, etc). I played around with this the other night for almost two hours without great success. The main machine itself can route for itself to the ISPs net but nothing else. Thanks Chad
