You are going to want the your clients to work well with your NAT.
Your vendor is going to have to spend money to do this.  The cost
of doing this will be passed onto everyone else that buys this
client as a direct monetory cost and/or extra complexity in the
product.  The later also increases the cost in maintaining the
product.  It also stops the vendor developing other products as it
takes additional resources to do this work.
