Network problem with IWP

[BluiSh]

Hello

This problem that i have is related in some way with my last post, I have 2 machines connected to a regular clabe modem given to me by my ISP, the main machine with my file has an ip address: 192.168.1.65, the other machine is connected via internet remote card to the same cable modem, this machine has the ip: 192.168.1.64.

I already shared with the Internet option the main file and try to access via web browser with the second machine and doesn't work, I already checked and set the port 90 because is not possible with 80, so I set port 90, in my web browser I type http://192.168.1.65:90 the address that gives me the file of the main computer and gave an error, mean while if I type the same http://192.168.1.65:90 fom the main computer everything works fine but of course I don't need to check IWP from that computer.

I don't have any idea what is happening???

help please???

thanks

What was the error?

Is there a firewall in place on the hosting machine?
