I have a wrt3200 running expressvpn firmware and I want to use the rt2600 behind it to handle all connections. That way I can utilize all the security features of the rt2600 while still being behind the vpn of the wrt3200. What do the settings need to be to achieve this? Curious if this would accomplish what I want, wrt3200 lan to rt2600 wan, disable wifi on wrt3200 and leave dhcp enabled, enable wifi on the rt2600 but disable dhcp?
