Limited outgoing access to a url

Hopefully a simple query.

We have a f5 that we just use for incoming traffic and have no real need for outgoing traffic before (to the internet).

Recently we have a system that has to connect to a internet website for licensing functionality.

Never having to have to have done something like this before I am not sure how to best accomplish this.

Buying a SWG license isn't on the cards.

1. Is it possible just to write a afm rule and just have the application server have a default route on a internal self ip. (note not really sure around afm stuff).
2. Should I just make like a ltm rule that work backwards and have the create a single pool member as the destination website and have a listener on the internal interface. Once again make a default route for the license server as the listener ip?
3. Is there some other way/s to do this that is secure?

Just looking for some ideas and a pointer in the right direction as its something thats a bit out of the box for me having only done awaf and gtm stuff on the f5.

Cheers
