Switch – Can’t get to the Internet from VLAN on switch

I'm trying to setup a network lab to learn more about networking.

Equipment:

• 2 procurve switches.
• 1 Sonicwall firewall TZ300

The final outline:

• traffic from Vlan 10 on switch 1(port1) goes to Sonicwall (X0) to the Internet
• traffic from Vlan 20 on switch 2 (port 1) goes to switch 1(port 5) then goes to Sonicwall (X0) to the Internet

Current config of switch 1:

hostname "ProCurve Switch 2510G-48"
snmp-server community "public" Unrestricted
vlan 1
name "DEFAULT_VLAN"
untagged 1-9,16-19,26-48
ip address dhcp-bootp
no untagged 10-15,20-25
exit
vlan 10
name "customer"
untagged 10-15
ip address 10.240.10.1 255.255.255.0
tagged 1
exit

Current config of Sonicwall is:

At the moment my conputer on Vlan doesn't have Internet connection. However, it can get an IP from the DHCP function of the Sonicwall. I'm stuck on this for the pass week. I have no idea how to go about the second part of the final outline. If you have any idea, please point me to the resources. Thank you guys.

—-Edit with solution:
Thank you everyone for your help.

Part 1 of outline:
I removed the routing policies in the firewall.
keep Vlan 10 interface IP on sonicwall 10.240.10.1
Set Vlan 10 IP on switch 1 to 10.240.10.2

Part 2 of outline:
Create Vlan 20 on Lan interface on Sonicwall
Create vlan 20 on switch 2 with IP address: 10.240.10.3
Connect Switch 1 (port 3) to Switch 2 (port 1)
On switch 1 console:

 Switch01(config)# trunk 3 Trk1 LACP
 Switch01(config)# vlan 10
 Switch01(vlan-10)# tagged Trk1
 Switch01(config)# write mem

On Switch 2 console:

 Switch01(config)# trunk 1 Trk1 LACP
 Switch01(config)# vlan 10
 Switch01(vlan-10)# tagged Trk1
 Switch01(config)# write mem
