Pfsense multi-lan setup

  • Hello!

    First let me say, i love pfsense. I use it in several schools and churches as well as in my own home. I'm trying to setup pfsense as a gateway/firewall between one WAN connection and 2 lan's. 10.1.1.x and 192.168.1.x being the lan subnets, and and as the pfsense addresses. I can use one of them at a time, whatever NIC is assigned as my "LAN" device. I know both NICs work as that "LAN" device, so I don't think its a problem with the hardware. The problem is that whatever device is the "OPT1" NIC the connection never works. I can't ping the pfsense box as it just says its timed out and I can't ping from the pfsense box to another machine in that subnet, that times out as well. So my question is, can I do this with pfsense, and if I can, what seems to be the problem?

    Any help would be GREATLY appreciated.

    Thanks so much,


  • Yes, it is working. I am using this.

    I thinke firewall rules is clear for both LAN connections.You have to allow the traffic from LAN side.

    If you are using Automatic outbound NAT rule generation in the NAT configuration, there will not be a problem, too. If it is manual, you have to configure it, as far as i know (I use automatic)

    in the INTERFACE menu, click on the OPT1 and scroll down and uncheck the boxes in "private networks"

    On OPT1 - are you using DHCP ? Did you enter the gateway and DNS correctly ?

  • Have you enabled that interface?

  • My apologies for the late reply  :( I didn't mean to ignore you guys. Thanks for your input, it turns out the switch was bad that the interface was plugging into, so once we replaced it everything worked perfectly! thanks for all your help.
