Modem -> Firewall -> L3 Switch -> VLAN no internet access

Hey,

First time configuring something like this. I can't seem to get internet access on the switch

Configuration

Modem -> ASA 5506 (Firewall) -> L3 Switch (Aruba 2930)

I can't seem to get internet through the switch but can on the firewall. Not sure what im doing wrong, any help would be appreciated!

L3 Switch Config:

ip default-gateway 172.25.1.254 snmp-server community "public" unrestricted vlan 1 name "DEFAULT_VLAN" no untagged 2 untagged 3-28,Trk1 ip address 172.25.63.1 255.255.255.0 exit vlan 64 name "Data VLAN" untagged 2 ip address 172.25.64.1 255.255.255.0 dhcp-server 

Firewall (ASA 5506)

interface GigabitEthernet1/1 nameif outside security-level 0 ip address dhcp setroute ! interface GigabitEthernet1/2 bridge-group 1 nameif inside_1 security-level 100 interface BVI1 nameif inside security-level 100 ip address 172.25.1.254 255.255.255.0 ! 

Modem is connected to ASA 1/1 ASA 1/2 is connected to L3 switch Port # 1 L3 Switch Port # 2 is connected to a laptop

DHCP is setup on the L3 switch which works but internet access is the only thing not working. Internet works if I directly connect laptop to the firewall.
