I'm having a problem accessing specific sites, amazon.com and forums.sonicwall.com. When I to run a traceroute on amazon.com it hits 3 hops and then starts timing out. I get no hops on forums.sonicwall.com. I have no problems with any of the other sites. I have a Sonicwall 250m firewall and we are running Avast Endpoint Protection Suite.
I put sonicwall.com in the trusted sites list and even removed Avast off of one of the domain controllers to see if the problem was with Avast. I have flushed the DNS cache on both DCs, restarted the servers and the firewall.
If I connect a laptop directly to the router I can get to amazon and to forums.sonicwall.com without problems. I can run ping and traceroute from the firewall with no issues.
The only time in the last few days I was able to access either site was right after I rebooted the Zone router. The firewall shows nothing in the logs.
Does anyone have any ideas on what might be going on?
Thanks!
Mike
