I recently installed UTM in a Hyper-V instance with three NICS (wired LAN, wireless LAN, WAN). The wired LAN goes to network switch of wired devices and wireless LAN goes to Asus RT-N66U in AP Mode. When I have the two LAN interfaces separate (separate subnet/DHCP/DNS), the wired and wireless clients can get DHCP just fine. When I bridge the two LAN interfaces, the wired clients can get DHCP without a problem but the DHCP for wireless clients is blocked somewhere.
I scoured the logs to see if any of the DHCP traffic was getting blocked but no luck, the firewall log shows no DHCP traffic. The DHCP live log just shows repeated DHCPOFFER and DHCPDISCOVER lines for my wireless devices. I tried creating various rules to allow the DHCP traffic, even trying an Any->Any->Any rule, but still had no luck.
Am I missing something simple? I figured maybe it was the RT-N66U blocking the DHCP requests but why would it work with the separate LAN subnets.
EDIT: Just realized that this is probably the wrong sub-forum, this should be under the Networking sub-forum.
