huhu.
is there a possibility to limit the access for clients to defined hosts/
IPs? some ftp-servers (e.g. "ProFTPD", http://www.proftpd.org) allow
apache-style directives like

  <Limit LOGIN>
    Order deny,allow
    Deny from .evil.net
    Allow from all
  </Limit>

to deny access from *.evil.net but allow all others.
if using the following topology:

      Internet <-------> Firewall with ftp-proxy <-------> ftp-server
 (abuse.evil.net)     194.12.34.5       192.168.0.1     192.168.0.2

...the ftp-server "thinks" the client is the ftp-proxy ("192.168.0.1")
and
the access-limitations above don't work (e.g. I'm not able to filter all
connections from the domain "abuse.evil.net").

are there any solutions? I miss something like

  DenyConnections *.evil.net, bill-gates.com, 207.46.230.220
  AllowConnections *.suse.de

in the "ftp-proxy.conf" file.
