IP-IP routing - Need urgent help!

[krishnarc5]

Hello,

How does the IP routing work?. My network is setup as below:

Modem => Windows server(2003) => Switch(20 port) => VICIDIAL SERVER + Clients.

The Static IP assigned is for the modem. The VoIP provider has configure the IP at their end and tells me that I should do IP Routing to ensure the static IP is mapped to the private IP on VICIDIAL server. I need some help!

Thanks,
Kris

modem => Router

Router => Switch (20 port)

Switch => Everything Else

In the router you define the "forwarding" of the ports to the windows server or the vicidial server

http (port 80) would go to your windows server if you have publicly accessible websites in it

smtp (port 25) would go to your windows server if you have a mail server in it

ports for SIP & IAX would go to your vicidial server.

SSH (port 22) should not be forwarded anywhere unless your router can change a port on the outside (choose one like 333 or 444, but NOT 22) and have it forwarded to port 22 on your vicidial server. if you expose port 22 as SSH on the web, you WILL be attacked.

Alternate: If you use your Windows box AS the router, you can substitue it where the "router" is in the scenario above, but you must then have TWO network cards.
