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.

Subject: CGNAT
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
