But wouldn't the end users be behind a double NAT in this scenario? (ISP's nat, end user's router's NAT.) Lots of voip protocols break when they try to deal with double NAT, and I'm sure there are other that will break too.
- ay 16y agoEven single NAT is not trivial when a few hundred thousands of active users are behind it, just because of the sheer scale. For a major part of the users "The Internet" == "The Web", and applications like Skype use any available transport including avian carriers, this limits the impact. But does having NAT increase the code complexity and increase the maintenance cost ? It does. So, I would treat it as a short-term high-interest loan. If you do not have other choice - sure, go for it. But if you can avoid it - you will avoid a couple of gray hairs too.
