All firewall notifications are for port 53??

    Hi..

    I'm using ESS v4.0.474 and I have started to notice that each time I launch an app which requires network access, the firewall prompt shows the remote computer as my ISPs primary DNS address and is showing the traffic on port 53. It used to show the remote computer of the website or service the application is connecting to and its associated port (80, 25, 110 etc). I can't pinpoint for sure when it started happening as it's only affecting my XP partition and I usually use my Windows 7 boot for day to day pc stuff and ESS v4.0.474 is running perfectly fine on there. Is this related to a ESET update which affects XP only?

    I'm aware I could just set a rule to allow outgoing udp access to the dns servers on port 53 and that would generate the usual prompt but I would just like to know why this is happening.

    Thanks for any suggestions :)

    Bump...set up ESS for a friend the other day and got the same notifications on their machine too. Would really appreciate an explanation for this as it never used to happen.

    Hello,

    Any time you try to access a webpage (ie: google.com, yahoo.com, msn.com) the computer has to first ask the DNS server where it is. This is done on port 53. If you have created a rule for port 80 which is the default HTTP port, then you will not see a notification for the page itself, only the DNS request port. Once you create a rule for this, you should not see it again.

    Thanks for the reply WayneP. It does answer the question as to why this has just started happening and why it doesn't seem to affect my Windows 7 installation either??

    Up until a few weeks ago, I never saw an ESS firewall request for port 53 regardless of what OS I was using. Just seems strange that it has just started to appear but doesn't affect Win7.
