We currently have a FTP server on our DMZ. We are unable to acces the FTP server from an internal host even though their is an ACL present and we see the ACL taking hit counts. If we use NSLOOKUP on the host trying to access the FTP server and then try to connect we are able to connect. However after a while it times out and NSLOOKUP has to be intoated again. Has anyone ever seen or herd of this? I dont understand why typing NSLOOKUP allows a connection to the FTP server.
