Multi Vlan on 1 lan or multi lans?
-
I am currently running a VM pfSense box to firewall 6 different networks plus my primary wan, and a secondary wan for servers. The VM server has multiple vlan's trunked into the VM Network, so I have added virtual nics to the pfsense with each lan having its own vlan'ed interface. This works great, allows me to keep the different networks secured from each other via firewall rules, but still allows me to decide what ip's can cross between networks where needed. The problem this is opened up, is I am wanting to setup some of the additional packages, like squid and havp, ect. Some of these packages will only allow 1 interface to be selected. So, I have read that you can add multiple subnets to 1 nic (lan), but if I do that can I still firewall between them? Or what would be the best way to accomplish my goals here? I am open to suggestions that I might have missed. Thanks
