If I understand your scenario correctly, I think you could do this without an iRule. You can configure your VS on x.x.x.10:443 and the pool member(s) on port 10. Just make sure port translation on the VS is left at the default of enabled.

Hi,

 

 

I want to use a wildcard vserver that will be a /23 network and only use two nodes listening on multiple ports to reduce on the amount IP address space allocated, So there will be multiple vservers pointing

 

 

eg

 

x.x.x.10 >> node A, node B tcp_10

 

x.x.x.11 >> node A, node B tcp_11

I see. I haven't tested this, but I think you could use the default load balancing algorithm to choose the pool member IP address and then change the destination port based on the last octet of the requested IP address.

LB_SELECTED is an event triggered when a load balancing decision is made. You can get details on the other commands on the iRule wiki (Click here).

 
 when LB_SELECTED { 
  
    log local0. "[IP::client_addr]:[TCP::client_port]: Request to VS [IP::local_addr]:[TCP::local_port]\ 
       Default selection: [LB::server]" 
  
     Use the node command to change the destination port of the selected pool member 
    node [LB::server addr] [getfield [IP::local_addr] "." 4] 
  
    log local0. "[IP::client_addr]:[TCP::client_port]: Changing to node:\ 
       [LB::server addr] [getfield [IP::local_addr] "." 4]" 
 }
