Trouble with Static ARP

  • We are using pfsense 2.0.3 
    We have two subnet one with WAN 192.168.9.X (NATED Public) and another Lan with 192.168.1.X.  I added Static mappings in LAN  and checked Deny unknown clients and Enable Static ARP entries as soon as I checked and save I got disconnected

    I couldn't get at least web configurator from the allowed system.neither from LAN nor WAN Please help me to solve this issue.
