Questions about vlan routing

Hello gentlemen,
I need help from the most experienced.
I have the following vlans configured on my core switch:
1 - Default - 192.168.1.2/24
2 - IT - 172.17.31.1/24
3 - Fin - 172.17.26.1/24
4 - My Default gateway is 192.168.1.1 (My Firewall).

I don't want communication between vlans, but I need them to be able to go out to the internet, going through the firewall.

 

I have tried to configure static route, enable ipforwarding, ACL denying traffic between vlans when ipforwarding is enabled, but still without success.

Can someone please help me?

 

 

Sorry for the mistakes I use google translate.

They not able to access the internet.
I need to avoid communication between IT and Fin vlans, but they must be able to go out to the internet.

I deleted all the acls. It didn't seem like a good solution. I believe that the solution is routing.

Greetings,

What exactly is without success? Are they not able to access the internet? Or are they able to access the internet but also the other vlans?

Can you share the relevant parts of

show config vlan
show iproute

and also your ACLs and how you applied them.
