How do I enable Subinterfaces for a Trunk?

Hello all,

I'm used to another known firewall vendor but I decided to give this for my home network a try since the other solution is way too expensive.

My goal is to use a single link between my switch and my Sophos appliance so I do not need lots of cables for every single vlan I plan to implement

This is my setup:

I use a Cisco switch

sw e0/1 configured with access vlan 10, e0/2 with access vlan 20

sw e0/0 is configured as enq1 trunk which carries vlan 10 and 20

How do I set this up on Sophos? I am used to subinterfaces which means I enable the parrent interface which does not need an ip address and then I can create subinterfaces below it with the vlan tags for the subinterfaces. How does this work on Sophos?

I configured vlans and put them into a zone and I also created a dhcp server in that vlan on the Sophos but my clients won't receive an ip address. I have no problems if I do not use a trunk between the switch and the fw and just a single vlan
