I stumbled across this article about changes in DNS resolution that are effective on 5/5/10 here: http://www.theregister.co.uk/2010/04/13/dnssec/
I then the java tool found on this website here: http://labs.ripe.net/content/testing-your-resolver-dns-reply-size-issues
Sure enough the test fails for me with this error:
"Your resolver was only able to get packets SMALLER than 512 bytes"
The recommended action is adjust my hardware firewall to allow large UDP packets through. My RV042 is my hardware firewall and I cannot see where/how to do that.
Can anyone help please?
