sg115w not able to provide a bridged network on internal WiFi adapter

https://community.sophos.com/kb/de-de/122080

If  your DHCP Server ist not the UTM, than you must configure a DHCP Relay on the UTM, maybe even a firewall rule.

Greetings 

Thank you Peter for the KB.

Bob (BAlfson) said in 2015 "The problem is that you can't Bridge-to-LAN with built-in wireless" (using Sophos w-Appliances).

Is this still the case?

Is the work-around https://community.sophos.com/kb/de-de/122080 from Juli 2016 still the only valid option?

The workaround is no longer necessary, but you do have to read the Help - in the Bridge to AP LAN section, it tells you how to make this work with a local WiFi device.

Cheers - Bob

Thank you Bob, I don't exactly know what you are reffering to as there are many similar entries. Could you pin point?

Or are you referring to "online help" or other documentatations outside the Forum?

Sorry, I wasn't trying to be facetious.  I was referring to the context help that you can access when you're on the 'Wireless Networks' tab (my highlight):

For Local WiFi Device: To create a Bridge to AP LAN you need to edit the Local WiFi Device on the Wireless Protection > Access Points > Overview tab and enable bridged to AP LAN. In addition, you need to create a new interface on the Interfaces & Routing > Interfaces > Interfaces tab and select the bridge. You also need to have a DHCP server on the Network Services > DHCP > Servers tab so that the client can receive an IP.

122080 covers the same thing, but in a clearer manner.  I agree that the help on this is only meaningful to someone that already knows the answer.

The net of it is that, for example, to have the local WiFi device broadcast an SSID that is bridged with "Internal (Network)," you must change the Internal interface from 'Type: Ethernet' to 'Type: Ethernet Bridge' and select the wlan# virtual NIC to be a part of the bridge.  This extra step is neither necessary nor possible with standalone APs.
