VLAN ACL on 3400cl

VLAN ACL on 3400cl

Simple requirement: configure a GUEST VLAN at a remote office that allows access to the internet, but NOT any internal resources.

ISSUE: I can ping devices on VLAN 1 from VLAN3. This cannot be the case.

I have learned that ACLs are required to achieve this result. Can you please assist with the correct ACL commands?

Firewall <--> Procurve 3400cl <-- Metro Ethernet --> Procurve 2626

1 port on Procurve 2626 is needed for this VLAN. It should get access to only the internet. The computer on this port is configured manually with the static IP address: 192.168.93.100/24.

Configs below.
