Question is - Should this be a difficult thing to achieve. Id rather not have to redo all of my Public address space/DMZ. The question really is (I'm been told it cant be done by a colleague here - However I have a suspicion he is just being slack about it). - Is it fairly commonly "not possible" ? - or as a rule common and reasonably "easy"
have 2 public sub-nets one 14 IPs other 6 IPs so /28 other /29
