Do i need VLAN in my firewall with Cisco switch access ports untagged

Hi everyone,

I'm not so good with VLANs and now I need to connect my Sonicwall NSA 2400 firewall to Cisco switch with these settings:

ISP Internet Connection connected from Juniper router to Cisco port 47 which is VLAN 10 access port untagged. Let's say the public IP is 192.10.10.1

WAN X1 connected to Cisco port 1 which is VLAN 10 access port untagged

DMZ is for ports 5-34 which is VLAN 11, all access ports untagged

Currently my Sonicwall is configured WAN X1 with IP 192.10.10.2

Then there is DMZ transparent mode configured 192.10.10.2 with range of all IPs from that network (192.10.10.2/24). And all my servers are connected to this zone. This X2 is connected to Cisco port 5.

Do I need to tell firewall those VLANs? I read somewhere that if all ports are access ports untagged they should work without making subinterfaces in firewall.

Now the problem is that I can't access Internet from servers in DMZ ports (5-34). 

Hope someone got the idea what I'm trying to do. 

BR,

Ville
