[bhaskarmulinty]

Hi,
    I configured DHCP with series of from 10.0.1.2-10.0.1.254.Lan IP is 10.0.1.1.I configured WAN with satic IP. My problem is i am getting IP from DHCP but unable to communicate with WAN.
If i configured class C network i am able to communicate with wan.Is it supports class A network..?.

Thank You

Stop thinking in class a/b/c
Define subnets with /24 /16 /8 (or whatever subnet you need)

Are your LAN and WAN in different subnets?

Are the clients configured with the correct default gateway?
