Cisco ASA incoming FTP connections problem when "inspect" IS enabled.
Posted on 2008-06-16
We have a Cisco ASA 5505 providing security for 2x servers in a data-centre. The servers behind the firewall both host FTP servers of their own and connect outbound to other FTP servers.
First problem we had was FTP from the internet to the servers was not working. We got rid of the "inspect ftp" statement - and all was fine. This unfortunatly causes problems with FTP connects these servers make to other servers out on the internet.
Any advise would be apprechiated.
