Basic VLAN Configuration

[eca2]

I have a basic HP Procurve Switch setup, with 2 PC's and a Firewall connected to the switch.

The switch is configured with 2 vlans and 1 Trunk port. My expectations are that I will be able to access the Internet with this configuration. After setup, I cannot connect to the Internet.

What is the issue here?

This is how I connected the resources:

Ethernet cable from Firewall to port 48
PC1 connected to port 2 (vlan 2)
PC2 connected to port 5 (vlan 3)

This is how I configured the switch:

[vlan Configuration]
switch1# conf t
switch1(config)# vlan 2
switch1(vlan-2)# untagged 2
switch1(config)# exit

switch1(config)# vlan 3
switch1(vlan-3)# untagged 5
switch1(vlan-3)# exit

switch1(config)# write memory

[Trunk Configuration]
switch1(config)# trunk 48 Trk1 trunk

switch1(config)# vlan 2
switch1(vlan-2) tagged Trk1
switch1(vlan-2) exit

switch1(config)# vlan 3
switch1(vlan-3)# tagged Trk1
switch1(vlan-3)# exit
switch1(config)# write memory

Cannot access Internet from either PC

Thanks in advance!

Please review the config of the firewall.

Also:
A "trunk" is in HP terminology a link-aggregation and not the trunk you perhaps know from Cisco.
