i have a new modem and have submitted a case requiring remote assistance. my modem is currently in my house behind my router/firewall. the instructions say " configure your firewall to allow the device to connect to the host ra.peplink.com". devices on my side of the firewall can connect to any outside address so i am not sure what is needed. are they saying that i need to set up a dmz or something so that ra.peplink.com can see my surf soho or does it really just mean that my surf needs to be able to see the outside world?
