Hello,
I need to open port 21 from two specific external IP addresses to the same internal FTP server. The external IP addresses are consecutive x.x.x.1 and x.x.x.2. When I entered static (inside,outside) tcp <External_IP_1> ftp <Internal_IP> ftp netmask 255.255.255.255, I had no problems. But when I entered the same command with <External_IP_2>, I got an error saying Duplicate of existing static.
I need to allow FTP access to my internal server only from these two external IP addresses, how can I accomplish that?
Thank you,
