G+_Russ Wickstrom Posted March 30, 2015 Share Posted March 30, 2015 I have a simple NAT question. I have a DSL modem which uses NAT and a separate belkin wifi router which is NOT dd-wrt compatible. The router is also using NAT, but I have both set to use adjacent ips in the same NAT space. Would I need to swap out the router to avoid the NAT within a NAT issues?

G+_Akira Yamanita Posted March 30, 2015 Share Posted March 30, 2015 You potentially have two options. 1. Put the DSL modem in bridged mode. Your ISP may have instructions on this or support might be able to do this for you. I deal with business accounts so I'm not sure if this request will be accommodated on residential accounts. 2. Don't use the WAN/Internet port on the Belkin router. Disable DHCP on it and connect everything on the LAN side. If it has an "AP mode", set it to that.

G+_Jason Marsh Posted March 30, 2015 Share Posted March 30, 2015 I had an AP behind a combo AP/Router/DSL Gateway, and it worked fine. I then changed the combo unit to run only as a DSL modem, letting my AP handle the business of passing my DSL credentials to the modem in the combo box, and saw no significant change in ping or bandwidth measurements. Long story short: Double-NATing on a home or small office network isn't likely to cause noticeable trouble, but will add some latency as your packets traverse the NATs. Even if you only have one NAT on your premise, you're likely to be double-NAT anyways, as most ISPs are using NAT already to extend the IPv4 address space.

G+_Russ Wickstrom Posted March 30, 2015 Author Share Posted March 30, 2015 Akira Yamanita Thanks! this idea may break a few things on my network, but nothing that cannot be repaired quickly! I'll look into this. Link to comment Share on other sites More sharing options...
