Good Morning Nicolas, Is Olfeo located on the DMZ too, or is it located on another zone? From what I understand the wifi users rely on the proxy to access the web. That being the case,do the guest users' browsers have the proxy setting to forward the web traffic "get" requests to the proxy server? We do not need a PBF rule, and we can just have a security policy from LAN to DMZ ( and have interface Source NAT, if the proxy squid is not directly on the firewalls DMZ interface subnet ), so that the GET requests are routed from the wifi users to the proxy squid on DMZ. As mentioned earlier, we also require the security policy from DMZ to Internet and a NAT from DMZ to internet. Please let me know if that worked BR, Karthik
