I really get turned off when people post a picture and walk away with little to no detail. What are you trying to accomplish?

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!
