Your lead on the network would ask more questions but why not do as you want plus connect the router to the Cisco and use it as before? I see no reason why not given only the story so far.
Can someone please tell me the best way to setup my network.
I am a comcast business customer with 5 static IPs.
My equipment consists of:
Cisco DPC3939B Business Wireless Gateway
Asus RT-AC68U Router
TP-Link 24-Port Gigabit Ethernet Unmanaged Switch
Before I upgraded my service to include the 5 Static IPs, I had it setup like this:
Comcast Modem/Router -> Asus Router -> 24 port switch
I would still like to be able to use the Asus router as it has Wireless AC which the new Comcast Wireless Gateway does not.
I also need to have 1 computer in my network on a separate static IP. I can plug this directly into the Cisco DPC3939B.
Thank you for the help.
