Slave Router with Primary Modem/Router


Dec 17, 2012
Hi All,
I have just been reading an old post about running a Slave Router off of a Primary Modem/Router. That all makes sense for the setup side of it. My question is about open ports for devices connected to the Slave Router.. For example, I have certain ports open on my PS3 for playing Call of Duty online. Will all of the traffic for these ports simply flow through the slave router or do I need to open up all the same ports on the Slave Router? Any help would be appreciated
