Firewall on bridged interfaces?

This might not be possible on Sophos UTM, but here goes...

I've got Sophos UTM Home License is running as VM under Hyper-V.
Virtual interfaces are VLAN'ed in Hyper-V.

I would like to keep all LAN clients on a single /24 subnet - but still transparently separate certain clients from others with firewall rules.
(Since a lot of media devices don't take well to routed subnets)

I thought that I could bridge two interfaces and still use firewall rules between the original interfaces.
(I've done this in the past with m0n0wall).
But as far as I can see, only the bridge (and not the original interfaces) can be used as firewall source/destination afterwards?

Am I missing something?

Best regards
Martin

Hi Barry,

A late thank you for the answer [:)]

Transparent filtering would have been a great bonus for me, for limited guest access.
But I guess that I will have to find a workaround for that.

(Just seems silly to have to set up a secondary firewall simply for that purpose).

But thanks anyway.

Best regards
Martin
