Modem setup with Sonicwall TZ170 »

That ought to work. As RadioDoc indicated, it is the subnet mask on the LAN side that is causing your problem. The modem use a subnet mask of 255.255.0.0, but that's on the WAN side of your router, so should not be a problem.

Re: Modem GUI w/ Router - ISO Definitive Answer

As far as being able to get into the modem's GUI from behind a router, Setup A does not work, and neither does Setup C when I use 255.255.255.0 as the subnet mask for the LAN. Sounds like you've been able to do this successfully. If you have a moment, please post your network config, including how you have your modem setup, and I'll try and duplicate it here. I'm starting to think that I have a bad modem.

Re: Modem GUI w/ Router - ISO Definitive Answer

This is how 5100b and router should be setup so you can access both.

5100b is doing pppoe off course.

Your router should have a LAN IP of 192.168.1.1 and subnet of 255.255.255.0 and set to DHCP mode.

Then once that is done hit apply/save on the router and reboot your machines if they are being DHCP'd from the router.

I had this setup for 18 months and it worked flawlessly.
