The result is double NAT. That is, the NAT functionality is done twice, once by the modem and once by the router. Some people think double NAT is bad.
I agree with you. I have never had a problem with double NAT. It has worked just fine. And it has the advantage that you can still easily access the modem for config and for statistics. I would leave the 6100 as a router unless there is a specific problem that needs to be solved.
There is a trivial problem that can occur. The 6100 defaults to 192.168.1.* for the LAN IPs. And some routers also use this. That gives a conflict (router WAN IP is on the same subnet as router LAN IP). However, that is easily fixed by either configuring the router to use a different range of LAN IPs, or configuring the Westell 6100 to use a different range of LAN IPs (say 192.168.2.*). This is easy to configure on Westell modem/routers and is easy to configure on most home routers. |
