I recommend you to take a look at DANOS. https://danosproject.atlassian.net/wiki/spaces/DAN/pages/416153601/Carrier+G... - A very active open-source project. - Sponsored by AT&T. - Uses Vyatta (and DPDK for good performance) - The Routing Engine is based on FRR. - Syntax sounds like Junos. - Is the ONLY ONE open source project(at least that I know) that implements CGNAT on Bulk Port Allocation mode(not deterministic/predefined). - Had very good improvements on PCP recently. - Supports a few NAT-ALGs. I and some good friends here in Brazil had some good experiences with it. Marcelo Gondin wrote this tutorial in pt_BR, mentioning about a case with: 26Gbps / 1.5Mpps / 11502 simultaneous clients / 192 used Públic IPv4 addresses. https://wiki.brasilpeeringforum.org/w/CGNAT_Bulk_Port_Allocation_com_DPDK Em sex., 19 de fev. de 2021 às 11:57, Steve Saner <ssaner@ideatek.com> escreveu:
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
