ioFTPD problems with a certain ISP???

[comeandgetme]

I have a strange problem with all my users connecting from a certain ISP (Telia adsl)?

I have had this prob from the beginning, so the problem didnt suddenly turn up.
At first I thought I made some strange config in the ioftpd.ini, but it wasent an error on my part.

I reinstalled ioFTPD one more time, and before I did any editing to the ini I created
a account for one of my Telia users. When he tried to connect to the server nothing happens, only message he gets is connection lost.

------------------------------
When he uses FlashFxp

Connecting to xxx.dyndns.org
Connected to xxx.dyndns.org -> IP=xxx.xxx.xxx.xxx PORT=xxx
Connection failed (Connection lost)
-------------------------------
The account works if u use any ISP other then Telia ADSL

Can someone plzzzz help me

Sounds like hosts.rules was blocking the connection.
