So one interface on our sonicwall is our wired LAN. Another interface has a wireless router plugged into it. At first, this separated the two networks, and someone on wireless could not see anything on the wired subnet. This has changed. Now people on the wireless are able to ping the wired LAN ip addresses. I tried blacklisting that range in the wireless router to stop this- but it doesn't work. I figure what I need to do is add a rule in the sonicwall that prevents the wireless IP range from seeing the wired IP range per this article here:
My question is.. is this the right way to go about this, and is there any additional info that I need to know about help follow these steps in this article, i.e. options of WAN & LAN in the fields mentioned? Any help is much appreciated.
