[SOLVED] DNS leak other than Comodo

It won't let me browse to airvpn.org.

Hello!

Here you're probably wrong, because you wrote your message while connected to the VPN.

My dos prompt stuff is attached.

It shows that you have connectivity inside the VPN but your computer can't resolve names. You can only browse to airvpn.org because it's in the hosts file and does not need DNS resolution. It is a DNS issue. Can you please try to change DNS on your physical interface and set 10.4.0.1 as primary (preferred) DNS IP address?

I attached the client logs in the previous message, if the client logs are the output from COmodo.

Please right-click on the Air dock icon when you're connected to the VPN, select "Logs", click "Copy to clipboard" and paste in a message.

Kind regards

How do I change my physical adapter IP number? Sorry I'm not sure if you mean my router or my network card or how to do that.

Wait a sec..since I changed that preferred DNS I think it's working. The block rule is on and I'm on the VPN and I don't see leaks on DNSleaktest. I also can browse. I think.

Not sure how that DNS preferred server was 0.0.0.0 before. I think everything is working. The 3 IPs that show up on dnsleaktest.com are

in the range of 74.125.186.152 74.125.186.151 and 74.125.186.145 and I think those are from you guys, right?

Thank you so much for taking so much time to help me! This is truly excellent customer service and I really appreciate it.

Hello!

Glad to know that the problem is solved. In dnsleaktest.com you correctly see only Google DNS, which is the last DNS queried by the Air servers.

Thank you so much for taking so much time to help me! This is truly excellent customer service and I really appreciate it.

Thank you!

One last thing: What are the entry IP addresses and/or rule I'd create for this network zone (as I may want to try some different servers to determine how fast my speeds are):

My speeds are currently like 1.2MB/s and they're usually about 25MB/s. Maybe this is because in my details I see all UDP and I notice you mention that if there's a speed problem, use TCP? I'm not sure how to set it so that when I connect it's through TCP. I'm trying to learn; sorry, just missing fundamental understanding of routing and network rules but I'm starting to get it.

For your comfort, you might define a Network Zone (for example [Air servers entry IPs]) containing only the entry-IP addresses of our servers and then set two rules like

Allow TCP or UDP In/Out From In [Air servers entry IPs] To MAC Any Where Source Port Is Any And Destination Port Is Any

Allow TCP or UDP In/Out From MAC Any To In [Air servers entry IPs] Where Source Port Is Any And Destination Port Is Any

Thanks again.
