Correct if I am wrong,

> access-list 100 permit tcp host 100.1.1.1 eq ftp 10.1.1.1 0.0.0.255
established
This will allow return traffic back for your initial session establishment.
> access-list 100 permit tcp host 100.1.1.1 eq ftp-data 10.1.1.1 0.0.0.255
established
This is not an established session, remote end creates a new session so if
you make is as below, it should work.
access-list 100 permit tcp host 100.1.1.1 eq ftp-data 10.1.1.1 0.0.0.255
