Question is: what is the best practise to filter ip address within vlan from reaching each other.
In your situation I would have to say you can handle this better on the ASA than on the L3 switch. Ofcourse it depends on how complicated the ACL are going to be. ASA will give you alot more flexibility managing the ACLs.
Should i trunk all my vlan to the Cisco firewall? (For easy vlan restrictions: but is that best practise?)
From the standpoint of restricting traffic and monitoring traffic I think it would be the best situation. In this situation ofcourse the ASA becomes even more critical device as it handles traffic between ALL of your networks.
If youre going to go with trunk interface you should probably consider doing a GEC between the switch and the ASA.
Usually when I've seen a setup with a routed link from ASA to L3 switch there usually has been no need for ACLs between local Vlans.
Or do ACL on the core switch itself? but what if i have tons of servers ip that needs specific ports blocking or etc.
ACLs on routers/L3 switches are fine if theyre simple but personally I find them to be absolutely tedious to manage. With ASA you can easily create "object-groups" to manage the networks and services and use them in the ACLs so you wont have to write multiple lines of ACL to achieve the same result.
How would i be able to manage all my ACL on the core switch.
To my understanding you would have to do all the editing through command line interface. On the ASA you can either do it through command line interface (which is still alot better than in routers/switches) or with ASDMs graphical user interface.
As I said before if you need to build complex ACLs on a router/switch, it will be tedious to manage and do changes. Also as the router/switch isnt a stateful device like the ASA so you have to take more into account while planning and managing your ACLs so you dont accidentaly block some critical traffic.
