I need a little/lot of  help I am new to openWRT. I have installed whiterussian 0.9. On a Linksys Wrt54GL v1.1. I need to configure the router  as a test bed for two OS X servers mimicking a larger network. I would like to have both servers connected but each in it's own Vlan (ie port 1 IP'S 192.168.2.X and port 2 IPS 192.168.1.X). Each ethernet interface serving dhcp. I then need the two separate vlans to be able to communicate... I could PING 192.168.2.5 from 192.168.1.5  while  both networks connect to the outside world via the WAN port.
please help this is a dire emergency and money is well non existent I do not think I can get my boss to buy a layer 3 switch for test. Any help would be much appreciated.
Not a coder so please go slow.

I suggest first reading this tutorial on vlan http://www.smallnetbuilder.com/content/view/30071/54/ In the webif^2 (if you installed X-WRT) you can define some additional vlan. Setting all routing etc and iptables I think still has to be done by hand. There is some info in the wiki look for "ethernet switch configuration" or vlan.
