Hello. I've already posted into the German Section but maybe the international General Plattform is more frequented.
I have a WLAN Network (VLAN 100) created via Unifi Controller.
A corresponding interface is created in the Sophos UTM:
Primary DNS is the Windows Domaincontroller.
Firewall Rules:
WLAN-Intern-100 (Network) <-> Any <-> Internal Network
WLAN-Intern-100 (Network) -> Any External (WAN)
NAT -> Maskierung: WLAN-Intern-100 (Network) -> External (WAN)
Webfilter: The WLAN-Intern-100 Net was added to the permitted Networks.
The WLAN network works so far, the WLAN clients receive an IP from the DHCP, DNS also works (DC can be reached), etc. Access to the internal network or between the networks is also possible. The problem is that the clients in the WLAN network do not have web access. Teamviewer still works. Also Ping to external hosts, but anything else is blocked. The web filter is on default, which also works for the internal network so far.
The internal Network, which uses the same Webfilter, works. if I temporarily disable the web filter completely, then the WLAN clients no longer have a network,
which seems strange as the internal Network works (just w/o Webfilter Funktion). Actually, the WLAN should also work without the web filter function?
Anyone with an Idea?
