I ran a firmware upgrade of a Sonicwall TZ100W from 22.214.171.124 to 126.96.36.199 and now have issues loading some webpages from the lan. I can tracert to yahoo.com and ping same but when opening a browser, the browser just states 'connecting' and never loads page. I can however get to sports.yahoo.com with no issues.
On the sonicwall, I have now turned off all Security services etc and still no joy.
I have set DNS on the server to OpenDNS as well as ISP dns
Another oddity is if I go to abcnews.go.com, the browser loads the header of the page in the browser title bar but then will not load anything else (even after clearing browser cache and resetting browser to defaults).
I can browse many other pages no problem google, msn, bbc, etc
