Help! ISP gives /30 and /27 but cannot use /27 for FTP
ISP gave a /30 ip block and behind is /27, i setup port 3 external as /30 and port 4 external as /27 and added a secondary IP for ftp. But i setup ftp for the /27 and i'm unable to connect. i'm able to ping it but cannot access. FTP proxy incoming has NAT from external ip of /27 to the internal IP.
Please help, is it configuration problem?
