Thanks for you advice. I am certainly perplexed by this as the feature set certainly makes it sound as if it can, see http://www.tp-link.gr/faq-1220.html for an example.

Yes, the switches with routing function support inter-VLAN routing. This is how you configure it:

1) Create VLAN interfaces and assign IP addresses to the interfaces.
2) Use the interface's IP address of the VLAN as the gateway for the corresponding subnet on connected devices.
3) Enable a dynamic routing protocol or create static routes on the switch for the VLANs.

For example:

Switch A handles VLAN 10, subnet 192.168.1.0/24, switch B handles VLAN 20, subnet 192.168.3.0/24, both switches are connected through VLAN 30, subnet 192.168.2.0/24.

1) On switch A, create both VLANs 10 and 30:

[CODE]Switch_A# configure
Switch_A(config)# interface vlan 10
Switch_A(config-if)# ip address 192.168.1.1 255.255.255.0
Switch_A(config-if)# exit
Switch_A(config)# interface vlan 30
Switch_A(config-if)# ip address 192.168.2.1 255.255.255.0
Switch_A(config-if)# exit
[/CODE]

2) Use the interface IP 192.168.1.1 (VLAN 10) of switch A as the gateway on connected devices.

3) Create a static route to next hop 192.168.2.2 for subnet 192.168.3.0/24:

[CODE]Switch_A(config)# ip route 192.168.3.0 255.255.255.0 192.168.2.2
Switch_A(config)# show ip route
Codes: C - connected, S - static
* - candidate default
C 192.168.0.0/24 is directly connected, Vlan1
C 192.168.1.0/24 is directly connected, Vlan10
C 192.168.2.0/24 is directly connected, Vlan30
S 192.168.3.0/24 [1/0] via 192.168.2.2, Vlan30
Switch_A(config)#
[/CODE]

Configure switch B accordingly for VLANs 20 and 30.
