I have a Cisco Pix 506E Firewall setup and is working fine currently. We have outgrown our DSL connection and have had a T1 installed. I'm kinda new to this network stuff but I know I can't just unplug it from my DSL modem and plug it into the T1 Router. In the process of changing over we had only 1 external ip before now I have a block of them I would like to change the NAT around a little. I have the following services:
and normal Internet traffic (web)
and in the future I would like to bring our web site internal instead of being hosted on the net.
I think the NAT just looks at port trafic and sends it to what ever server IP the function is served on.
: inbound traffic on port 21 is sent to my ftp server's ip address etc.
I just thought of this. My new T1 has a Cisco 1700 Series router after the D-mark wouldn't this need to be configured as well?
I still want every thing to go through the firewall but I would like to have severel different outside Ip's
current static outside IP
000.000.000.001 port 21 nats to 000.000.111.100 - Ftp Server
000.000.000.001 port (Term. services port number can't remember what it is) nats to 000.000.111.101 - Terminal server
I would like to have somehting like
new static outside Ip's
100.000.000.050 port#21 nats to 000.000.111.100 - FTP Server
100.000.000.051 Terminal services port# nats to 000.000.111.101 - Terminal Server
100.000.000.052 WebSite traffice Port# nats to 000.000.111.102 - Web Server
Like I said I'm new to this so any help would be nice and please excuse my ignorance if my thoughts do not match reality.
