2 pc's in different VLAN cannot ping each other firewall enabled

[mikailb]

Hello,

I was setting up a small local network to test different servers like wsus, ad, dns, ... I have a layer 3 switch  with ip routing (Cisco Catalyst 2960-X series) and 2 pc's in 2 different VLAN's. They can only ping each other when firewall is disabled in both but firewall enabled nothing happens. Anyone any idea why i'm getting this please?

Thanks!

Which firewall, the Windows firewall on the PCs ? Did you allow ICMP ?

Hello,

Yes standard Windows firewall enabled no pingback. Do i have to allow ICMP in Windows or Cisco switch please?

Thank you very much for your fast answer!

Switches don't have firewalls so it is on on the PCs you need to do it.
