    Ok so i have 2 NICs(WAN and LAN) on the lan i have 5 subnets.  I have tried using the aliases and adding custome routing and nat entries but every  time i ping the router from a machiene set to a subnet IP address all i get is "Destination host unreachable"(slax)

    …idk what the deal is...

      How did you get 5 subnets on the LAN?

      We do what we must, because we can.

        woops, i think i used the wrong wording, there Vlans.  Im trying to replace a cisco 2610 with a pfsense box.  The current configuration has 5 vlans running on it att set up staticly.  im hoping to just set up the pf box the same way the old router was beacuse i cant get to all the pc's to change them to a new setup.

          Can you post a diagram of how you've set things up.
          Also screenshots of your firewall rules and modifications to the NAT rules you did.

            I dont have any diagramming software so here goes:

            Router->
                Switch->
                     Computer Group A (Eth)
                Switch-(cisco catalyst 2610>
                     Computer group B (WiFi)
                     Charter modem

            As for the NAT and Firewall rules i will need to get those later as i currently dont have access to the computer cabinet(under lock and key)

            This is all the subnets that the current router has(I hate IOS…but the router is to old to support any GUI software)
