create a nat rule for different external Ip's.. if u ave one external IP.. then U can use different incoming ports to route different servers to port 80

what non-zero is suggesting is to set up so that you access one web site like:

and the other one:

note the ":81" means that the web site is accessed on port '81' instead of the default port (80)

then on your router, you create an additional port forward rule (you would already have one for port 80) to forward port 81 outside to port 80 inside.

that is your only option unless you obtain a second IP address from your ISP.

This will be fine for CRM as they only have to setup once.  My next question would be setting up through command line would it look like this

ip nat inside cource static tcp 192.168.5.x 80 interface fastethernet4 80

If I do it like this I already have one like it for exchange.  I guess I don't know the command for asking for the outside port...

not 100% sure on this, but if that is the only config rule for the existing redirect then you only need to change the port to 81 at the end of that line:

ip nat inside source static tcp 192.168.5.x 80 interface fastethernet4 81

assuming that your fastethernet4 port is the outside interface?

That makes sense now.  I am assuming that I can do the same for SSL also.  Thanks

yes - one thing I was going to suggest is that you can use https for one site and http for the other, so then you won't need to use the port-specific notation any more:


ip nat inside source static tcp 192.168.5.x 80 interface fastethernet4 80
ip nat inside source static tcp 192.168.5.y 80 interface fastethernet4 443

(or something like that)
