No Access to Some sites

vmgng3077 · ‎02-10-2008

Every thing is working well in my firewall, I have the DMZ working ok, I can access the net, I can create a VPN into my network.

The only problem is that I can access most os the sites in the web, but there are some that do not work like http://www.microsoft.com or http://www.sapo.pt I don't understand what is going on.

Please help me.

I have a capture of the packets in a computer in the in-zone where I first reached site www.europeantour.com and then www.microsoft.com.

I can see a good redirect and then that I lost about 11000 bytes of packets.

Could it be a MTU problema?

Thanks,

Victor

Hi

check the match protocol dns, I had the same problem where www.intel.com wouldn't work. Change the default value from 512 to 1024, hopefully this might solve the problem
