I guess my ISP uses some subpar hardware because the connection keeps dropping at peak hours. I want to implement a failover system without having to buy some expensive router which I would not be able to justify with my normal usage.
Wanted to know some other ways how people do it .
I run two pfsense routers and use CARP. 1gbps/50 cable modem with 5 static ips available on both pfsenses, and a 1 gbps symmetrical FTTH with 1 static ip also available on both pfsenses (but uses CARP to know which is “live” - it uses pppoe, which makes this possible with 1 ip).
My current single point of failure is my single main switch. Works very well though. I’ve had 100% uptime for over a year!
