 This usually happens when you have aliases on $ext_if.  In this case 
 ($ext_if) expands to a round-robin pool with all addresses assigned to 
 the interface.  If you want to use the primary address on that interface 
 you can use the "($ext_if:0)" syntax to exclude aliases.  If the address 
 you want to use is an alias, you have to specify it manually.
