Ftp Error 421 Service not available loggin in from LAN into the router

[Mark-Walter@t-online.de]

Hi,

I've compiled and installed the kernel 2.6.15. With 2.4.28 everything
worked fine.

With the new kernel I can't login over FTP from the LAN into the router
but it's possible to login from the router into the LAN.

This is the error message that comes while login over FTP from LAN into
the router:

421 Service not available, remote server has closed connection

Is this something new in the kernel 2.6.15 ?

I'am using iptables as a firewall.
