Can anybody help me with this, its driving me mad...
First of all, what do you really want ? Running a ftp server on your own
computer or being able to access external ftp server, or perhaps both.
Have a look at those two pictures in order to see the differences between
active and passive mode (french link but it does not matter) :
What rules have you tried to run by now ?
thanks for the quick answer and sorry for the incomplete description.
Right now I cannot fetch the used ruleset from the server but my
intention is to keep it as secure for my server as possible.
I want to run an ftp-server to give the possibility to upload something
but also need access to an external ftp-server for backups. At least
apt-get should find a way to fetch packets through the firewall. The
decision whether to run active or passive on my own ftp-server depends
on the security level of the underlying ruleset.
