Loadbalance redirects

Hello everyone.

 

 

First, I'm not belingual so excuse my English.

 

 

In my configuration, I have one pool named all_support_pool_fla and 4 servers. My goal is to share http and ftp traffic like this : two servers deal whith http traffic and two others deal whith ftp traffic. But all the servers are in the pool all_support_pool_fla.

 

Members of my_pool had been defined like that :

 

172.20.50.100:80

 

172.20.50.100:21

 

172.20.50.101:80

 

172.20.50.101:21

 

172.20.50.102:80

 

172.20.50.102:21

 

172.20.50.103:80

 

172.20.50.103:21

 

I want to create an iRule which can share traffic between them. I know this can be done easily by create two pools, but I like to make my life harder:P

 

 

By taking exemple on this iRule I made another one :

 

 

when RULE_INIT {

 

set ::compteur_http 1

 

set ::compteur_ftp 1

 

}

 

 

when HTTP_REQUEST {

 

if { [TCP::local_port] eq "80" } {

 

if { $::compteur_http == 1 } {

 

set ::compteur_http 2

 

pool all_support_pool_fla member 172.20.50.100:80

 

}

 

elseif { $::compteur_http == 2 } {

 

set ::compteur_http 1

 

pool all_support_pool_fla member 172.20.50.101:80

 

}

 

}

 

 

if { [TCP::local_port] eq "21" } {

 

if { $::compteur_ftp == 1 } {

 

set ::compteur_ftp 2

 

pool all_support_pool_fla member 172.20.50.102:21

 

}

 

elseif { $::compteur_ftp == 2 } {

 

set ::compteur_ftp 1

 

pool all_support_pool_fla member 172.20.50.103:21

 

}

 

}

 

}

 

 

But there is two problems. First, FTP traffic doesn't run. I think this is because I used this in a block with HTTP_REQUEST. Should I use CLIENT_ACCEPTED or something else?

 

And secondly this iRule is run each time a client connect to the virtual server, so every time the client is directed to the server 172.20.50.100 (for HTTP of course), and I want to use a load balancing like Round Robin (no more complication it's useless:D) in the iRule.

 

 

Please help me.

 

Thanks.
