Hi,
We are not able to download files from an external/public FTP server. The following abreviated config from our Cisco 2621 perimeter router. Any suggestions would be appreciated.
Thanks. Said

Hi,
To make it clear SFTP is actually SSH which is in TCP 22. FTPS is FTP over SSL/TLS - there are two mode to this and most firewall doesn't work with one of them, some firewall doesn't work with any two of them.
Are you using SFTP or FTPS? If you are using FTPS, I suggest you either use plain FTP or SFTP.
Regards,
Dandy

Hi Danny,
I have built a FTPS server, SSL encryption. Our firewall is the IOS firewall features of the Cisco 2621 perimeter router. My next step is to open up inbound connections to port 20: access-list 103 permit tcp any eq 20 any. The server sits on the DMZ with Public IP. The server will have anti-virus software, and documents will be in PDF format, so the files do not get altered.
