(Sorry if this sounds stupid or what not, again im just toying around trying to learn a thing or to by doing this.)

READ AT OWN RISK): Blabble: I have a (small) homelab. I have experimented with pfsense running virtually with esxi host i have on the network. My problem has been if pfsense (would be gateway/ router/firewall) fails and dhcp services go down im unable to manage or troubleshoot the server and or connect to any other device on network. Thus im searching for a simple way to solve or atleast maintain dhcp so in a case where pfsense explodes, i still have dhcp and can connect to the actual host and other computers on network while troubleshooting it.

Simple question: What would be a good route going about doing something with a setup like this? Dedicated dhcp server?

More blabble
Should i do something like use windows server 2012 (virtualized) as a dhcp server and set that up with a failover server on another machine? So i can continue to troubleshoot and manage pfsense as a firewall/router/gateway in case anything goes wrong I just want to keep pfsense in the equation cause im experimenting with its features and what not but i need a reliable way to have dhcp ( or in other words ability to still manage the host server and vms / other devices) should it fail.
 
Critical infrastructure like firewalls, DHCP, and DNS servers are assumed to always be running. DHCP especially so. If your firewall is unstable, then yes, have a separate DHCP server, but that does increase the complexity of your network because PFSense pretty much does that for free.
 


Yes i realise this. Id need rather a temp fix to this problem while i iron out the kinks in pfsense.
So what would one use for a lightway dhcp server? windows server 2012? ( my lab is based around linux and windows well is a hog with my very precious resources.
