Question about routing
Question about routing
I've had no issues with that as long as DHCP is active on the wan, letting the upstream server assign addresses. Setting static is a solid choice for devices acting as servers. Would you like me to add a small switch in front of PFSSL and divide the home side with the web server?
Where not dealing with the WAN here. We're focusing on the LAN side. The user wants to verify if his PFsense box fails. The internet is the only thing he risks losing. If the PFsense box becomes the DHCP server and it crashes, everything falls apart. BOOM, no DHCP server. You can't. Most ISPs only provide one IPv4 address. Unless you have a business account and/or pay extra each month.
If DHCP is being handled internally, not by PFsense or the USG, then there is nothing to worry about as long as the switches stay up and are connected (which doesnt appear to be in the diagram) If DHCP is being handled by either the PFsense or USG, set the lease for a week or something well within the time that you can get it back up and running. This will keep current devices functioning at least.
The issue isn't with DHCP or the switches, it's about understanding how to connect from the USG to the pfSense.
To ensure USG handles routing when PFsense stops working, you must enable VRRP.
I'm trying to understand this concept, but why would you need two routers connected together?
