HOW TO: vsftpd, linux and linksys router

Recently I've got vsftpd running from behind my BEFSX41 both in PORT and PASV modes so I thought that I share my set-up since FTP servers are quite a hot topic here ;)

My config:
BEFSX41 1.43.4 (any BEFSx should be OK)
vsftpd 1.1.1 (1.1.0 and up supports PASV from behind NAT, get it here: vsftpd.beasts.org )
RedHat 7.3 (any linux should be fine)

Router set-up:
Forward port 21 TCP on UPnP Forwarding page
Forward ports 65000~65534 TCP on Port Range Forwarding Page (any range, it's up to you)

vsftpd.conf set-up:
pasv_enable=YES
pasv_min_port=65000 (same range as on router)
pasv_max_port=65534
pasv_address=100.100.100.100 (here comes your WAN IP)
...all other variables are set to default values

And since I have dynamic WAN IP from my ISP here's a little script running from cron to update vsftpd.conf with current IP (I use free dynamic DNS service www.dynu.com )
code:
#!/bin/sh
#vsftpd.conf IP update by Brano See Profile
vsftpd_conf=/etc/vsftpd.conf
vsftpd_log=/var/log/vsftpd.log
#change to your domain name in next line
my_ip=`host your_host.dynu.com | cut -f4 -d" "`
vsftpd_ip=`grep pasv_address $vsftpd_conf | cut -f2 -d=`

if [ "$my_ip" != "$vsftpd_ip" ] ; then
( echo ",s/$vsftpd_ip/$my_ip/g" && echo w ) | ed - $vsftpd_conf
echo `date` "$vsftpd_conf updated with $my_ip IP address" >> $vsftpd_log
fi

...hope this helps to somebody :)

·WOW Internet and..
Great info! You're right, FTP servers are a constant hot topic here. So... you'll find your post added to the FAQ: »Linksys FAQ »How do I setup an FTP server behind my Linksys? . Many thanks!

I wrote a document about setting up FTP on the SMC Barricade and it is online at »www.gbnetwork.co.uk/smcftpd/

A couple of sections are specific to the SMC but most apply to any router. It covers setting up FTP Serv-U under windows and Pure-ftpd under Linux.
