I have several queries regarding the Firewall or may be i am not able to understand the basics of the firewall. So here is the some changes i had done with the settings of the firewall. What i have done is that i had started an outbound rule which allowed http, https ports, while all the clients had to go through the DNS server. The result i found that it did not open any pages. So i did the necessary changes and this time what i did was only to allow all the outbound requests from the DNS server to outside.. With these, all the clients can open the pages. To make it more small i allowed only the DNS from the dns server to communicate with outside this did not allow clients to open the pages. So now i want to know that whenever we request a page is it necessary to connect to our own DNS?
