And did you setup your ISP router to nat these networks? Since your not natting them on pfsense? You also have a asymmetrical setup here for devices to to and with devices in your lab..
192.168.10.0/24: LAN, for normal machines
192.168.20.0/24: DEV, for dev/test machines
192.168.30.0/24: SRV, for servers made available to the internet
Your best solution here is to just put your isp modem/router into bridge mode and use pfsense as your edge router/firewall. Or just double nat.. I have yet to see a soho gateway from an ISP that allows you to nat other networks other than the one that is its lan, etc.
