Firewall and DNS

by Toivo Talikka In reply to disabling windows firewal ...

Disabling the firewall does not change the behaviour from the browser's viewpoint. When the firewall is on, it stops packets from outside wreaking havoc in your PC, but all browser requests initiated in your PC are passed on to the next level regardless.

Talking about the next level, does the browser give an error message?

Go to Control Panel - Network Connections and right click the Local Area Connection icon and select Status - Support - Details... You need to have the following there, among other settings:
- Default Gateway: the IP address of the router in your network which can be the DSL modem/firewall in a small home network
- DNS Servers: at least one entry, either your router inside the local area network or the address given to you by your ISP

You can go to the command prompt and type in nslookup and press Enter. At the prompt type in www.google.com and press Enter. If you get an error message, either the DNS server address is incorrect or obsolete or the DNS server, usually at your ISP's premises, is not functioning.

Firewall and DNS

by Toivo Talikka In reply to personal firewall within ...

Personal firewall should allow DNS queries to be sent from the PC and it should also allow the responses to come in.

A lot more depends on the router or modem/router you connect to the internet with. They have firewalls, but they should also allow the DNS queries to be sent and received in their default configuration.

Your PC may be set up to get the DNS server information from your router. You may need to check the router settings, but it is best to talk to the ISP first, especially if you got the modem/router from them. They should be able to tell you the IP address of their DNS server.

You can then set up the address of the DNS server in the TCP/IP settings of your Local Area Network connection, or if the modem/router has been configured correctly and your PC gets is dynamic IP address from the router, your PC will get the correct DNS server address automatically.
