Hi, My name is Fabio Andres Miranda,student of computer science at uninorte.edu.co This is my problem and i hope someone points me with this, i am very confused, even though, i have the support and help of some teachers at college, this still very hard: I'll buy a leased line of 19,2Kbps from a local telco that uses Cisco HDLC protocol. the network diagrama is something like: Internet<->Cisco 4500(TELCO)<->DSU/CSU<->leased line<->DSU/CSU<->Wan card on sever(my office) The interface between the DSU/CUS's and the DCE's(in this case the telco's cisco4500 and mine wancard) is rs232. I'll have assigned 6 class C ips. I'll use a Wan card that recives the line on server A, and all the possible destionation *IS* the same server A. It's like: All the packets that go out from my network are sent by the server and all the packets come to my network are recived by the SAME server. I will use the 6 ips, they will be registered domains, and, all the 6 ips will be on the same server (aliases), so, any request from the outside is RECIVED by the server (using the wan) and ANSWERED by the same server(with unix daemons over the same wancard). The server runs FreeBSD-3.4 and it has a built-in firewall on the kernel for protect the lan(3 clients on my office).Of course, the needed daemons of a normal web server are configurated on the same server. My doubts are: What type of routing should i use? What configuration needs for FreeBSD? How can i configurate it? Would you please give me a config example? let's say the TELCO ip range is: 200.20.20.1 to 200.20.20.255 ok, i'll have 6 ips of them, let's say: 200.20.20.10 200.20.20.15 What's my subnet/broadcast/netmask? (This is in any book, i know, but the I will use the same as telco's?) Thanks for help...on Douglas Comer books about tcp/ip network, i read something that suits mine needs (probably): "Routes assigned by default":It's used for keep reduced the routing tables. The routing ip software look for routing table first, if destination net is not found, it sends the datagram to the "router assigned by default". "Routes by especific host": The routing is based in networks not in hosts. But, in some cases (like mine! fingers crossed)many routing ip software allow an admin to operate routing tables in order to debug network connection or to have more control over the datagrams. Which one suits my needs? How can i put this theory on practique? and put it on my network? and in my OS? on my rc.conf? in my rc.networks? ..etc. p.s. Please, i know "name-based" hosting is an option but i cant use due clients needs. FreeBSD rulez forever! __________________________________________________ Do You Yahoo!?
