CGNAT

Not the Cheapest option out there but the most rock solid one I have found is to install the extended service/multi service cards in the BNG and do it locally there. We are currently using both Juniper MX480/960 with MS-MPC cards and Nokia 7750 SR with ISA or ESA cards. Its also well worth running dual stack IPv6 as you can bypass 40%+ traffic from the CGN process for all that CDN traffic.

We are starting to look at CGNAT solutions. The primary motivation at the moment is to extend current IPv4 resources, but IPv6 migration is also a factor.

We've been in touch with A10. Just wondering if there are some alternative vendors that anyone would recommend. We'd probably be looking at a solution to support 5k to 15k customers and bandwidth up to around 30-40 gig as a starting point. A solution that is as transparent to user experience as possible is a priority.

Thanks
