Hi,
I moved my ftp server recently, and entered a redirection rule, but
passive transfers don't work. I think this is because the rdr on port 21
works, but the subsequent data channel connection from the client is not
similarly redirected.
$ grep -E 'ftp| 21' /etc/ipnat.conf |grep -v ^#
rdr le1 216.254.83.209/32 port 21 -> 192.168.1.5 port 21
map le1 192.168.1.0/24 -> 216.254.83.208/32 proxy port ftp ftp/tcp
What am I missing? Do I need "keep state" magic here? I thought that was
just to deal with fragmentation.
Thank you kindly.
