X2 is a Comcast connection behind an SMC 8504(?) whose IP address is 22.214.171.124 (the gateway for X2). Also plugged into the SMC via the built in switch is the WAN side of a pfSense firewall(also using 126.96.36.199 as the gateway). On the LAN side of the pfSense are WAPs for Public Internet use. Outlook Web Access is available to the Internet at 100.100.100.195 NATed to a private IP.
The issue is that hosts on the Public Internet Wireless are unable to connect to OWA. These hosts are behind the pfSense (for Captive Portal Reasons), but using the same network as the X2 WAN on the Sonicwall. I presume the Sonicwall sees traffice coming into it from an IP that is on its on WAN as some kind of 'spoof'??
How can I allow this traffic? I'kk try to uplaod a pdf diagram of this if I can
