Hello,

here is a sample configuration of active and passive FTP capable ServerIronXL :

! this one let the ServerIron do reverse NAT for connexions initiated by the real servers (in active FTP the real server initiate a connexion from port 20 to a high port)
server reverse-nat
server real FTP-1 10.64.0.38
! In ordre to the reverse nat to work the port must be bound
 port 20
 port 20 no-health-check
 port ftp
 port ftp keepalive
!
server real FTP-2 10.64.1.38
 port 20
 port 20 no-health-check
 port ftp
 port ftp keepalive
!
server virtual FTP 192.168.0.1
! this tells the ServerIron tha sessions initiated from the same source to any other port (after the fist connexion on port 21) are redirected to the same real server (this let us deal with passive ftp)
 port ftp sticky concurrent
 port 20
 bind ftp FTP-1 ftp FTP-2 ftp
 bind 20 FTP-1 20 FTP2-2 20
!

Hope this helps.

Regards,
Youssef Ghorbal

Hi guys,

I have a query regarding PASV ftp behind ServerIronXL. The scenario would be that a host behind the LB will initiate an FTP access to an external server. The problem is that it will need to open a random ports for it to establish a data connection to the server. That said, the host behind the LB cannot successfully connect. Is there a tweak on the ServerIronXL for this to run properly?

LB model: Foundry ServerIronXL
SW: Version 07.5.00eT12

Thanks,
Reynald
