Hi Alvaro, > 1) What is the HW recommended to the server, I'll hope to get 2000 users > registered. I have read the following are the hardware requirements: > > 1 pc server, a common compatible PC > 1 ISDN card (witch vendor is preferred?)
I wouldn't say the ISDN card is a requirement. You'll need some way of attaching your Kannel box to the internet to receive content from live sites. This could be using ISDN but would probably be better using a LAN if you have access to the internet via a LAN. The other concern is how your subscribers attach to the kannel box. Do they have a dial-up account they could use to access your network? If not, you'll need to provide some sort of modem pool and ISDN cards might be a solution here. The best solution would be for your subscribers to use an ISP so you don't restrict access by having only a few lines into your box. > 2) Is necessary to use a ISDN line account, can it work with a analog line? Yes, although analogue lines take longer to answer calls. > 3) Is posible setting up my WAP Gateway with a Lan card to access Internet > or I must use a moden connection? Yes, as above. If you have internet access via a LAN it's probably the best solution and Kannel should be able to take advantage of it. > 4) Is strongly necessary my WAP box have his own public IP or it can be into > a LAN? >From a point of view of retrieving content, kannel does not need a public IP. It can >connect to sites from behind a firewall or NAT which supports HTTP connections on port 80. You will need to listen for incoming connections from mobiles. If these are attaching to your network through a modem pool they can have the private IP address of the kannel gateway so long as they have a route to access this from the dial up connection. If your subscribers are attaching from the internet or an ISP, network operator, etc. then you need to make the WAP ports 9200,... available on a public IP address. This doesn't mean the kannel box has its own public IP address, but it will otherwise need a port mapping through a firewall so it looks like it does.
