We are small community ISP and have one central router on Mikrotik in use as an internet gateway. We have about 200 internet users and system which automatically checks and updates firewall every day according to bank account payments. About 15 years ago we started with some routerboard which had it's nand toasted within about a three months. So we have migrated to x86 router and changed it several times through the years. Now is a time to upgrade this router again and I would be glad to use some CCR router this time. But I have great concerns about Flash memory life. If there would be any way to replace NAND for SSD or so...
How do you handle frequent changes like firewall for paying customers ? Thanks for any advise.
