DSL Internet / LT2P LNS Server + Radius + Squid + Dns + Monitoring + Backup

Project is for network specialist / engineers only! Please bid if you have dont this before. Background: We are begining to sell DSL Internet services. The inbound DSL connection from the incumbant is delivered over a vlan into our main firewall/switch which then passes all LNS/LT2P traffic NEW (this project) LNS/L2TP/Radius Server for authentication Project Requirements: 1.) Provide network diagram of proposed installation and how traffic flows. 2.) Install LNS/LT2P Server 3.) Install Radius Server 4.) Require details on how to configure LT2P accounts for DSL/internet access. 5.) Need to specify which accounts have Static External IP address and which have internal IP addreses for recycling. ... break There are 3 classes of DSL we offer: 1.) Full Internet with Static IP 2.) Full Internet with Dynamic IP 3.) Limited Internet with internal IP - used for virtual private networks and linking to other internal servers for other IP services. ... Continue from above. 6.) Require 3 cli scripts to auto generate these users/ips/login information/etc... so we can integrate the scripts from an independant billing system/linux server. 7.) Install Squid proxy server to cache internet traffic 8.) Install DNS server to handle dns traffic with forwarders All servers to have real-time backups so HA (high availability is required). Will also need to link to zenoss monitoring or other realtime equivalent system. 9.) Need instructions to troubleshoot common issues 10.) Need reports / log instructions for common reports requests. if we are missing any components to please advise and suggest.
