Here is how I would do it: settings at your pfsense: make rl0 WAN with static config using the LAN IP of your DSL router as gateway make ral0 LAN enable DHCP Server at LAN and configure it correctly enable "advanced outbound nat" at firewall>nat>outbound and delete all rules after you enabled and saved (this way you are routing and don'T NAT any more) create a rule at WAN to allow access from your dslrouters LAN-subnet if you want to shut down access for the wifi hosts of your pfsense to your dsl-routers LAN subnet add a rule to block access from source any to destination dsl-routers lansubnet at the lan tab of the pfsense. place this rule above the "default lan to any" rule. settings at the dsl-router: add a static route for the wifi subnet of the pfsense with gateway wan ip of your pfsense

Thank you very much for answering my questions billm.  I'll try sticking 2 routers inbetween the modems and the pfsense box.  I'll let you know how everything works out.   ;D

I disable ftp helper but it didnt work properly, the work around I did was to only load balance my 80 and my 119 everything else through one of the wans.
