Outbound Nat causing loss of internet

[SirIrish]

Hi,

I have two gateways. I have a connection going out the non default gateway. That works and what's my ip shows the ip of the gateway it's going out. Great!!
Now I want to apply an outbound NAT to this connection. When I do that I cannot browse the internet on that server. I can still ping the internet.
Another issue is that I cannot ping the server from the internet using the NAT IP and cannot connect to it. I can ping the external IP Internally.

So I decided to remove everything and start from scratch. I believe I have removed everything and go to remove the alias and I get "Cannot delete Alias. Currently in use by" 
In use by what?
