L3 Switch not routing traffic

[msggumby99]

Hello, I set up this topology in Packet Tracer and it worked just fine. 

Any help would be greatly appreciated, Thanks

This is an internal network only.

I set up 1 C3560-CX switch in L3 mode and 4 C3560-CX switch in L2.

I can ping and connect to each switch with ssh and GUI

Layer 3 switch

enabled L3 by enabling ip routing
added the vlans 25,30 and 100 (management)
3 interface vlans 
vlan 25 172.16.1.0/26
vlan 30 172.16.1.64/26
vlan 100 172.16.30.0/24
setup 4 trunk ports, plugged the 4 L2 switchs in.

Layer 2 switchs

added vlan 25,30 and 100
set up the 8 ports as access and access vlan 25, access voice vlan 30
spanning tree pordtfast
set up port 10 as a trunk for a connection to the L3 switch
setup ip default-gateway  (vlan 100 172.16.30.254)

I added 1 client to each L2 switch.

the clients can hit the default gateway
no clients could hit each other.  They are a mix of win 10 and win 11.

There are no additional configurations.

End device able to ping Gateway ?

Fist thing come to our mind, End device has FW , so disable and test it

Also check from L3 switch are you able to ping end device ?

still issue post below information :

L3 switch :

show ip interface brief

show ip route

show run | in routing

show ip arp

show vlan

show span summary

show vtp status

L2 switch

show vlan

show vtp status

show interface status

End device any one :

no clients could hit each other. They are a mix of win 10 and win 11.

ipconfig /all

tracert to other client IP and show where it blocking.

Note : we expect there no ACL here ?

only add vlan to l3 SW and it will work 
do this by 

vlan 25
vlan 30
vlan 100

Sorry for the delay, I was pulled to another task

I went through the firewall settings and found that the firewalls were still on after a good effort to allow all connections. I found out that group policy controlled the firewall, so I went in to gpedit and turned them off and everything is functioning.

Thank you for the reply
