4. All rights reserved worldwide 3 Where to dial The ip buffer really has two methods of delivery over modem either across the Internet or to a private RAS server 3 1 Across the Internet Being able to dial out onto a cheap or free Internet service means the ip buffer can deliver data and alerts to anywhere in the world for the price of a local phone call It also means that the central system can be connected to an ADSL service that can handle hundreds of concurrent connections rather than having to maintain a bank of modems in the central site For such a scenario we recommend the following guidelines 8 Run the central system on a high priority ADSL service you want the line to be fixed guickly if anything goes wrong You will need fixed IP address assignments e Setup a firewall on the ADSL line that provides a service port mapping For example if running the SMTP email delivery option we suggest using a non standard port say port 20025 that the firewall will route to an internal IP address the machine that has the SMTP server Run the SMTP server behind the firewall Preferably use a product like Scannex s SECollector which acts as an SMTP server and delivers the data directly to a directory without having to store the emails in an InBox e Ideally if you have a DNS domain like scannex com and you can setup your own A entries create an entry like data scannex com and point the IP
5. address to your ADSL service o You can then program the ip buffer to connect to data scannex com and have the freedom to physically move the data centre by just changing the DNS A entry Of course you can choose to deliver by FTP push or email to a public InBox just as easily 3 2 Private RAS Server In some cases you may want the privacy of a private RAS server In this situation the ip buffer s ISP 1 telephone number should be the public number of the modem that s connected to the PC Obviously the PC can handle only one concurrent connection per modem Consequently this approach is more suited to small scale setups where having a public IP address for the central site is not possible or where there are no Internet accessible servers available This guide will show you how to create an incoming RAS connection on your Windows XP machine to service the incoming calls from the ip buffer s Page 4 Scannex ip buffer ANOO2 Using dial out over modem UK 2007 Scannex Electronics Ltd All rights reserved worldwide 4 Setting up the PC 4 1 Windows XP e Start up the Control Panel e Select Network Connections Select the task New Connection Wizard click Next New Connection Wizard Welcome to the Nev Connection Wizard This wizard helps vou Connect to the Internet Connect to a private network such as pour workplace network Set up a home or small office network To continue click Nest
