We have a firewall that enable us to block ports - our operating sys is win2k server. If our customer enters in the url box www.oursitename.com
on his IE, our server calls asp file that calls dll file doing some calculations and send the answer to customer IE again. It looks simple but, which port is to allow for recieving the customer IE order, and whick port to allow for sending an answer. As we read port 80 but how come the customer IE recieved tcp problem after displaying the url name on the bottom. And what is HTTP TCP UDP, are they related to ports allowance case if we did not block UDP in some cases it works. after many testing we were able to make it work but now the server IE cannot work on the internet we think its port is blocked which we do not know.
Does any body know THE FOLLOWING
- the Ports for get customer IE request
- the port for send an answer to customer IE
- the port to allow our server IE to access internet
- HTTP relation to TCP UDP ARP ICMP
