Hello @dwtdlt3000,
You have activate "ip routing" on your Switch but ther's no ip route..... that's the problem.
But, I suggest you to reconsider and adapt the Switch and the Router's configuration:
Create a ROAS on Router side ; meaning a sub-interface for interface GigabitEthernet0/1:
interface GigabitEthernet0/1
description --ROAS-SWITCH
no shut
!
interface GigabitEthernet0/1.10
encaspulation dot1q 10
ip address 10.0.10.1 255.255.255.0
ip nat inside
!
interface GigabitEthernet0/1.20
encaspulation dot1q 20
ip address 10.0.20.1 255.255.255.0
ip nat inside
!
interface GigabitEthernet0/1.30
encaspulation dot1q 30
ip address 10.0.30.1 255.255.255.0
ip nat inside
!
interface GigabitEthernet0/1.40
encaspulation dot1q 40
ip address 10.0.40.1 255.255.255
ip nat inside
!
ROAS: https://study-ccna.com/configure-roas/
On switch side, the interface facing Router's Gi0/1 interface, configure a traditionnal TRUNK:
interface GigabitEthernet1/0/48
switchport mode trunk
switchport encapsulation dot1q
switchport trunk allowed vlan 10,20,30,40
!
If you want "access to Internet" from the switch create an interface vlan 10 as example and add IP address. Test a pinf towards 8.8.8.8 with source <IP-interface-vlan-10>
=> No more "routing" needed on your Switch, acting as a traditional "L2" Switch.
Delete the DHCP server on Switch and confgure it on the Router
ip dhcp pool 10
network 10.0.10.0 255.255.255.0
default-router 10.0.10.1
dns-server 75.75.75.75
!
ip dhcp pool 20
network 10.0.20.0 255.255.255.0
default-router 10.0.20.1
dns-server 75.75.75.75
!
ip dhcp pool 30
network 10.0.30.0 255.255.255.0
default-router 10.0.30.1
dns-server 75.75.75.75
!
ip dhcp pool 40
network 10.0.40.0 255.255.255.0
default-router 10.0.40.1
dns-server 75.75.75.75
=>Your LAN should be able to access to Internet after that.
