Hello all, hoping someone can walk me through the process of setting up the following configuration. I'm not a networking wiz and only know just enough to be dangerous. I have very little experience with setting up VLANs and interfaces, etc.
I have an ASUS RT-N66U running v 1.28. I have a 2.4GHz wireless G interface and a 5.0GHz wireless N interface currently running. Attached to port 1 of the router is an 8 port unmanaged switch which has about 5 or 6 devices connected to it.
I also have various wireless clients connecting to either of the wireless interfaces. Everything is assigned an IP address from the 10.0.0.x IP block.
All traffic exiting the LAN is running through the WAN port of the router which is going to a Comcast cable modem. (WAN 1)
I want to add a wireless AP (WAN 2) that will plug in to port #4 of the router. I think this would result in a double NAT'd situation for the WAN 2 connection but that is fine as I am not worried about unsolicited incoming connections. I don't want to do round robin, load balancing, or a fail-over configuration. I want both connections to be active at the same time but only certain traffic would be able to use the WAN 2 connection based on the source IP and/or the outgoing port number. For instance only the device located at IP address 10.0.0.10 would be able to use the WAN 2 connection if it is establishing a connection to a server on port 25412. I need the router to make the decision of where to send the traffic. I believe this would require an IP filtering rule?
To add to the complexity I need all of the local LAN devices to still be able to see and communicate with one another. For instance, my 2 Roku's need to be able to see my Plex server. I have read some of the various tutorials but I don't know enough about the networking specifics to know if they will do what I want.
I created a map of my existing network but am not allowed to post it because I'm too new. :(
