I haven't used them, but 6-WIND is pretty proud of their CGNAT performance. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com ----- Original Message ----- From: "John Alcock" <john@alcock.org> To: nanog@nanog.org Sent: Tuesday, April 28, 2020 2:12:29 PM Subject: CGNAT Solutions Afternoon, I run a small ISP in Tennessee. COVID has forced a lot of people to work from home. I am starting to run low on IP's and need to consider CGNAT. I do have IPV6 space, but we all know that until we force everyone to move to IPV6, we need to keep IPV4 up and running. I could buy more space, but I am really wondering if that is the best option. It is expensive. I know CGNAT devices are expensive as well, but it looks like I could stretch it out a bit. My thinking is to convert about 50% of my subscribers to CGNAT. I am interested in vendors or devices you have used in the past. I already know about the pitfalls many of my subscribers will have with CGNAT such as VPN's, Gamers, etc. What are your thoughts on CGNAT vendors? A10Networks F5Networks Others?
