Troubleshooting VLAN Connection

[TheMetMan]

I cannot get a VLAN connection working. I have looked at several posts here, and elsewhere. I have read the pfSense Book on VLAN Setup and many posts and manuals on setting up my 8 port TP-Link Easy Smart Switch.
I am new to VLANs but not to pfSense.
I am pretty sure I have everything setup correctly, but I cannot connect.
I am running an SG-3100 Router with pfSense 2.4.5-RELEASE-p1.
To simplify things I will just talk about the following:
WAN is on mvneta2 connected to my ISP’s Router,
LAN is on mvneta1 10.6.77.0/24
VLAN20 is on mvneta1 as 10.0.20.0/24
VLAN30 is on mvneta1 as 10.0.30.0/24

Here is the DHCP:

For the NAT I clicked Manual, saved it and then Clicked Automatic again and saved it.
For Rules to begin with I just allowed everything:

My Switch is setup like this:

And Port 1 is plugged into LAN2 on the SG-3100

If I plug my laptop (running Gentoo Linux) into port 6 which is not on any VLAN on the switch I can connect with DHCP and get the normal address 10.6.77.11
If I plug in to port 7 then it is unable to connect.

I have tried rebooting the SG-3100 but no difference.
I can ping VLAN20 10.0.20.1 from the LAN and pfSense.
There are no packets showing at all when I try and capture packets in the VLAN20 Interface and attempt to connect.

What can I look at to find the cause of being unable to connect to VLAN20?

Thanks in advance.

SOLVED it myself in the end!!!
For anyone else out there with the same problem.......
It was Enable 802.1q VLAN mode in the Switch Settings on the SG-3100.

Interfaces->Switch->VLANS

I unchecked this so it was using Port Mode, left it at the default, and I can now connect.
