iRule for SNAT for Host IPs & Supernets based on specific customer

Hi Aaron,

 

 

One of our engineers modified the iRule a bit, and it works great for host IPs as well as supernets. Here is the iRule;

 

 

 

when CLIENT_ACCEPTED {

 

 

Loop through each line in the datagroup

 

 

foreach line $::syniverse_snat {

 

 

Check if the local IP equals the current line's subnet

 

 

if {[IP::addr [IP::local_addr] equals [lindex $line 0]]}{

 

 

log local0. "[IP::local_addr]:[TCP::local_port]: Matched [lindex $line 0], using SNAT [lindex $line 1]"

 

 

Use the SNAT IP

 

 

snat [lindex $line 1]

 

 

Exit the loop as we've found a match

 

 

break

 

 

}

 

 

}

 

 

}

 

 

 

Thanks a lot for your help!
