Hello, For users on the internal network, the Zope 2.6 FTP server works fine. However, we wish to expand the application to distributed clients over the internet. The hardware used is a CISCO PIX 501 firewall. The current settings are as follows: access-list outside-in permit tcp any host <WAN IP ADDRESS> eq 8021 static (inside,outside) <WAN IP ADDRESS> xxx.xxx.x.xxx netmask 255.255.255.255 0 0 The problem is, I suspect as per the FTP protocol, the client decides the local socket of the data channel (not very good for firewall support). However, I have been successful with other standard FTP servers using similar treatment. Is there a resolution to this issue? Thank you, Robert __________________________________ Do you Yahoo!?
