GTM Private to Public Translation

I have a GTM in DMZ using private IP addresses for wide IP. I need to translate the 1st three octets of the wide IPs to public addresses. I believe I have to use an irule to accomplish this. I tried ...

Hi Kai,

 

Below is the irule: when LB_SELECTED { if { [LB::server addr] contains ".10." } { log local0. "Pool member [LB::server addr]" set new_ip "1.1.1.[getfield [LB::server addr] split "." 4]"} elseif { [LB::server addr] contains ".20." } { log local0. "Pool member [LB::server addr]" set new_ip "2.2.2.[getfield [LB::server addr] split "." 4]"} }

The command I've posted is just a way to parse the last octed of your existing IP and then transform this IP into a new one. It does not changes anything on the wire yet. But you could use this command in combination with other commands (depending on what you're trying to solve). To help you further, I'd need some more details of the configuration you're trying to achive? Cheers, Kai
