Hi Steve We are looking at implementing a similar solution with A10 for CGNAT. 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. The numbers below are for a similar target of subscriber’s and peak bandwidth. We assumed a couple of numbers: Current Peak Bandwidth = 40G Remaining IPv4 traffic after migration = 20% (Seen references to 10% or 20% on this forum) Future Bandwidth Growth = 2x (no data behind this assumption) Future CGNAT’ed bandwidth = 15Gbps Equipment & budget lifecycle = 7Yr Getting that data led us to this price comparison: Solution Lifecycle/ Term Annual Cost/Sub Product Lifecycle Cost/Sub Lease IPv4 Cogent 7 $ 4.45 $ 31.13 A10 CGNAT 15Gb 7Yr 7 $ 1.21 $ 8.47 A10 CGNAT 40Gb 7Yr 7 $ 1.95 $ 13.68 Purchase @ $25 7Yr 7 $ 3.57 $ 25.00 The current plan is implement an A10 CGNAT solution after upgrading our network for IPv6. In the interim we will have to lease IPv4 to tide us over. I would be curious to see what other’s estimate the costs of various approaches. Feel free to ping me off-list for more specific numbers.

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.
