I recently had to force our Watchguard X10e firewall to reset to defaults because the person that set it up has left the company and didn't leave the password or any documentation of how it was configured.
Since then we are unable to access certain websites, but others work. I am unable to access experts-exchange.com, microsoft.com and yahoo.com for example, yet google.com and cnn.com work.
This happens on all of the network computers in addition to the server. There is no web filtering software running on the server.
The outgoing firewall is configured to allow outgoing traffic. Incoming is configured to allow ports 443, 25, and 4125 .
The webBlocker function is disabled on the Watchguard.
Any ideas on where to start looking. It almost acts like a virus of some type, but nothing is coming up on any scans. Everything else seems to work normally, just some websites are being filtered.
