restricting acces to ftp server

Hello,

i have a small anonymous ftp server (pure-ftpd daemonized). There are some people on my network who are connecting through our proxy server and i want to prevent that. So how do i forbid access from certain IPs?

thank you for your help

Re: restricting acces to ftp server

i would suggest to use iptables to block tcp to your ftp-server's port from a specific source ip. big_smile

Re: restricting acces to ftp server

If proftpd uses tcpwrapper .. you can limit it using that also. This way tou don't have to rely on a firewall for this ... (You can have both.)

Re: restricting acces to ftp server

You can set Pure-FTPd to only listen to it's own IP:

Bind 10.0.0.5 # set 10.0.0.5 to the IP of the FTP-server

This way, if users connect through your proxy (NAT/router?), they'll probably connect to ftp.yourdomain.com and the proxy forwards the request to the server. The server won't allow a connection since it only listens to connections going to 10.0.0.5 (not ftp.yourdomain.com).

You could probably also edit the user database and deny connections from certain IP's in there.

PS: I'm assuming you're confusing proxy with NAT/router.
