Need help with VLAN tagging on an HP Procurve

[eddyw4]

I have 4 vlans on a procurve switch.

VLAN1 - Network Devices (Server, printers, WAPs)
VLAN100 - Admin (Office workers)
VLAN200 - Teachers
VLAN300 - Students

There is a server doing DHCP. There are 4 ranges of IPs 1 for each VLAN.

The router is on Port 44. VLAN 1, 100, 200, 300 - Tagged
The Server is on Port 46. VLAN 1 - Untagged
The WAPs are on Ports 1, 11, 31 VLAN 1, 100, 200, 300 - Tagged
All other ports are on VLANs 100, 200 or 300 - Untagged

The WAPs all have VLANs 100, 200, 300. Each VLAN on a different SSID.

I have IP helper with the server IP on VLANs 100, 200, 300.

There are IPs from the different subnets on their respective VLANs in the switch. 

The gateway for each subnet is on a different subinterface on the router.

The router is a linux box. (Untangle)

***********************************************************************************************

The WAPs are not able to talk to the server, therefore no computers on the wireless networks can get an IP.

The server can only talk to the router if I change port 44 to untagged.

What combination of tagged and untagged ports do I need to make everything talk?

Do I need to put the VLANs on the subinterfaces of the router?
