NAt in the iRule

Hi,

 

Please, suggest the right solution for the following problem. I'd like to use BIG-IP to pass traffic through as router normally to the destination. I would like to put the additional server as proxy and change the destination address by the Big IP if the proxy is available. Then the whole traffic based on the destination address is redirected to proxy by Big IP. The proxy again assign the original destination address and forwards it to the destination through the Big IP again.

 

What kind of the iRule will cover such scenarios ? What kind of the VIPs are recommended ?

 

 

Thanx,

 

Robert
