20 vlans on single ethernet
-
Hi
i have 2 switches manageable (level 2) .
I have set up 20 vlan on the switch .
I want to make firewall rules between this vlan with pfsense via one single network card and via 19 virtual Interfaces .do you think the network card will get ?
Pc
Proc: core 2 duo e4500
Ram : 1 Go DDR 2 .
chip : Intel
Q35 Express Chipset with Intel ICH9DO
network card : Intel PRO/1000 PT Desktop Adapter .thank you in advance

I'd try to minimise the VLANs if possible simply for ease of management. I have five - and that's enough to think about.
I'd also suggest a better NIC - the one you suggest will work, but an Intel server adapter is recommended if possible. I'd also suggest using a PCI-Express NIC - the bandwidth between the board and the NIC is better that way (though check that you have a suitable slot on the motherboard with enough lanes).

As David already said, the network card should be server grade in your scenario, not a desktop adapter.
If the PC running pfSense will be sufficient depends on the actual amount of traffic you need to push. And with (that many) VLANs on a single adapter you might easily saturate it.
Remember that traffic between subnets/VLANs has to pass the NIC twice!And, as a hint, you only want to assign VLANs to the NIC. Don't mix it with an untagged subnet (you mentioned 19/20 VLANs).

Ok thanks we have bought a hp DL 120 G5 and 2 pci express intel 100/1000 server network cards for vlan, 10 vlan per network card .
What do you think with this configuration ?

Still you are talking hardware only. Sorry, I don't get impressed easily…
As mentioned earlier in this thread and elsewhere, what matters is the amount of traffic you want to push between subnets/ NICs. And you didn't give those numbers AFAIK!
