what do you mean by denied? Are they completely blocked? Does the connection hang? Do they get connection refused? Do they get a login prompt? Any entries logged to /var/log/messages on what packets are getting blocked? Are they using passive mode?

NAME
lastlog - examine lastlog file
SYNOPSIS
lastlog [options]
DESCRIPTION
lastlog formats and prints the contents of the last login log /var/log/lastlog file. The
login-name, port, and last login time will be printed. The default (no flags) causes lastlog entries to be printed, sorted by their order
in /etc/passwd.
OPTIONS
The options which apply to the lastlog command are:
-h, --help
Print help message and exit.
-t, --time DAYS
Print the lastlog records more recent than DAYS.
-u, --user LOGIN
Print the lastlog record for user with specified LOGIN only.
The -t flag overrides the use of -u.
If the user has never logged in the message
**Never logged in** will be displayed instead of the port and time.
NOTE
The lastlog file is a database which contains info on the last login of each user. You should not rotate it. It is a sparse file, so its
size on the disk is much smaller than the one shown by ls -l (which can indicate a really big file if you have a high UID). You can display
its real size with ls -s.
FILES
/var/log/lastlog
lastlog logging file
CAVEATS
Large gaps in uid numbers will cause the lastlog program to run longer with no output to the screen (i.e. if mmdf=800 and last uid=170,
program will appear to hang as it processes uid 171-799).
