Thanks for your responses. I thought you might be interested in this.
Apparently in Windows XP there is something called an Application
Layer Gateway. This needs to be set up in Kerio in order for FTPing
to be allowed. I learned this from someone else. Once I placed the
following rules in Kerio I was able to ftp from Dreamweaver. I assume
that Filezilla will work also.
Application Layer Gateway OUT
Single Port 21
Application Layer Gateway IN
Single Port 20
Hope this info is usefull to you. From a security standpoint does it
