Pfsense and ddwrt guest network guidance
I currently have a pfsense box (192.168.5.1) acting as a dhcp server with 2 nics, one for the modem wan and one going out to a ddwrt box (192.168.5.2) with a physical lan, the ddwrt box then is used as a ap for the entire network. I have wan disabled for the ddwrt box and the gateway set as the pfsense box as well as the local dns. My question is how would I go about setting up a guest ap with a separate subnet on the ddwrt box that is separate to the lan that can connect to the internet going through the pfsense box. I assume the solution would be something to do with vlan on both the two boxes and clever firewall rules. However I am a networking novice and came to this forum for help on this feat.
Pretty much my current setup (ddwrt provides nothing more than access points, pfsense handles everything else). You may want to have a read through here: https://forum.pfsense.org/index.php?topic=116980.msg720119#msg720119 Although the author is using lede/openwrt principals are the same.
