Hello,

I am running into some issues with my home network. I have gig internet from cox and the modem router combo they gave me isnt a great router. so i was trying to set up a layer 3 switch to act as an interim router and connect my own WAP to that switch. come to find out the cable modem/router doesn't support dynamic routing protocols so i went to configure a static route and i cant inside the modem/router. i was doing some research into putting it into bridge mode but i don't know how that works with a Cisco device? also i would then lose NAT. so next option would be just buy another router, put the modem/router in bridge mode and then go from there. so how does a modem bridge with a Cisco device if i was to buy a Cisco router for studying but to actually use if i have to or just buy like a TP-Link router and add a static back to my network.

Hi there,

The easiest solution would be to buy yourself a cheap Cisco ISR. Configure a Layer3 interface ('outside')and connect it to your ISP modem/router so that it is on the same IP subnet.

Configure the additional subnets on the ISR for the purpose of your lab. Configure source NAT to translate the lab subnets behind the 'outside' interface.

This will mean that lab traffic is NAT'd twice; once by the ISR and then a second time by the ISP router. However you will not need to worry about bridge config or any static/dynamic routing.

cheers,

Seb.
