More than one vlan on an interface
We are trying to configure 10 vlans on our pfsense server. the server has 2 physical network interfaces. one for LAN and one for WAN. Is it possible to configure all the vlans on the LAN interface. we created vlans on the LAN interface (em1) and then created a separate virtual interface for each vlan. we then assigned an ip address to each interface. however we were not able to ping the interfaces.
Yes, that works fine. So long as your switch is trunking all of the tagged VLANs using 802.1q to that port on pfSense.
We have configured trunking on the switch ports connected to our pfsense server. We followed this guide for configuring vlans (http://blog.stefcho.eu/?p=695). But we are not able to ping our vlan interfaces. The pfInfo page shows following stats for one of the vlan interfaces. In4/Block shows 29 packets blocked In4/Pass shows 0 packets. It looks like packets are being blocked. However we have configured firewall rules that allow all traffic from the vlan subnet. We also ran a packet capture on the the vlan interface. It showed arp requests being sent to the vlan interface, but did not show any arp replies. The problem seems to be caused by having multiple vlans on a single physical interface.
