Hello,
I see that you set ip helper
but
forwarding of BOOTP/DHCP (ports 67, 68) cannot be enabled with this command. (I assume that you made a typo, trying to add bootp port 67, but missed 6 - " ip helper-address 192.168.50.2 192.168.50.252 67 ")
Anyway :)
Try to use the DHCP relay commands to relay BOOTP/DHCP packets instead of ip helper
DHCP relay
Use the ip dhcp relay enable Interface Configuration mode command to enable the DHCP relay feature on an interface.
Use the no form of this command to disable the DHCP relay agent feature on an interface.
Syntax
ip dhcp relay enable
no ip dhcp relay enable
Parameters
N/A
Default Configuration
Disabled
Command Mode
Interface Configuration mode
User Guidelines
The operational status of DHCP Relay on an interface is active if one of the following conditions exist:
• DHCP Relay is globally enabled, and there is an IP address defined on the interface.
Or
• DHCP Relay is globally enabled, there is no IP address defined on the interface, the interface is a VLAN, and option 82 is enabled.
Example
The following example enables DHCP Relay on VLAN 50.
switchxxxxxx(config)# interface vlan 50
switchxxxxxx(config-if)# ip dhcp relay enable
switchxxxxxx(config)# ip dhcp relay address 192.168.50.2
OR
Just make all uplinks in trunk mode and add all needed VLANs in that trunks (including Sonicwall):
Sonicwall_X2(trunk add vlans 1,15,40,150,250,400)-----(trunk add vlans 1,15,40,150,250,400)gi1/12_(siteA)SG500_gi1/25(trunk add vlans 1,15,40,150,250,400)-----(trunk add vlans 1,15,40,150,250,400)gi1/25_(siteB)SG500_gi1/26(trunk add vlans 1,15,40,150,250,400)-----(trunk add vlans 1,15,40,150,250,400)_gi1/25_(siteC)SG500----
Hope it helps
Cheers,
Mike

You were right I had UDP/IP Helper enable... i disable it and added all virtual interfaces to Sonicwall.
1. IP lease have being resolved.
Now how do i get the Layer 3 switch to do all the routing? static routes are setup on SonicWall & Switch but when i setup the default Gateway on the clients as the interVlan on layer 3 switch devices cannot reach the internet.
