Communication across subnets!

Hey Guys,

So I have a server setup with a 192.168.253.31 address. The network has three vlans:

Vlan 10 with 192.168.255.0/24

Vlan 20 192.168.254.0/24

Vlan 30 192.168.253.0/24

All the servers connect to one "routing" layer 3 switch. Each port is segmented as untagged to be in the respective Vlans.

Now I have a pfsense box acting as my time server. It's address is 192.168.255.1 and it is plugged into a physical port on the switch assigned as untaged for vlan 10.

I need the server in vlan 30 to be able to ping and use ntp from 192.168.253.31 to 192.168.255.1.

Both interfaces are connected to the switch. I'm slightly confused how to do this. Do I do tagged ports? Do I make some kind of route?

I guess I could plug in another port into my pfsense box, and make that interface 192.168.253.1 then untagg the port to be in vlan 30. But I'm hoping that I don't have to physically go back into the server room if possible, it's a drive.

Anyway for me to get the server on: vlan 30 with an ip of 192.168.253.31/24 with a gateway of 192.168.253.254

to connect with the ntp server of 192.168.255.1/24 gateway 192.168.255.254

The gateway address for both devices points to the same switch, only on different vlans.

Thanks for any help!

P.S. Do I tagged vlan 30 on the pfsense port and then assign a vitural interface on the pfsense box?
