I thought I would run this by the forum in case there is someone out there who experienced the same issue. I have users behind an ASA5520 firewall running 8.x code who are unable to access a particular ftp site through a web browser or an ftp client such as FileZilla. Keep in mind that other ftp sites are accessible. I was notified of this as it worked in the morning of a particular day and then stopped working in the afternoon on the same day. Accessing the site from our guest network(different firewall) is possible. The SysAdmin insists it is a firewall issue. I have run the packet tracer on the firewall and the traffic is allowed. FTP inspection is configured. I get the same results when I try to access with IE or Firefox. Anyways, I thought I would post the questions to see if anyone has seen something like this before. If anyone is interested, the site is ftp://authordev.healthstream.com. TIA for any help or advice.
