I've used this ftp proxy for ftp connection.

 

https://devcentral.f5.com/codeshare/ftp-proxy-v10-and-up

 

My iRule

 

when CLIENT_ACCEPTED { TCP::respond "220 Welcome to the F5 FTP Proxy v10\r\n" log local0. "client accepted" TCP::collect } when CLIENT_DATA { set ftplogin [TCP::payload] log local0. "login is $ftplogin" if { $ftplogin starts_with "USER" } { You can set it up to use any DNS server you want. set dnslookup "10.191.31.60" set cuser [TCP::payload] scan $cuser {%[^@]@%s} garbage sitename scan $garbage %s%s cmd uid log local0. "$sitename" set ips [RESOLV::lookup @/OpusCapita/vs_dns_test -a $sitename] set ips $sitename if {$ips eq "" } { Input wasn't an IP address, take some default action? log local0. "$ips Input wasn't an IP address" reject } else { TCP::payload replace 0 [TCP::payload length] "" set ftp_serv "[lindex $ips 0]" node [lindex $ips 0] [TCP::local_port] log local0. "member adresa [lindex $ips 0] port [TCP::local_port]" } } TCP::release } when SERVER_CONNECTED { TCP::collect } when SERVER_DATA { set serv_data [TCP::payload] if { $serv_data contains "220" } { TCP::respond "USER $uid\r\n" log local0. "user= "USER $uid\r\n" " TCP::payload replace 0 [TCP::payload length] "" } TCP::release }

User can connect to my FP proxy VIP and connect to dest ($sitename) server. At the moment don´t use DNS. But when user try trasfer some data to FTP server. User see only timeout and no data sent. Can you please check where can be problem?

The 552 error code is returned by the FTP server and indicates that there was not sufficient space on the disk to upload the requested file. Note that this may be a lack of physical space, or a lack of space allocated by quota. This does not indicate a problem with your BigIP.
