I have a Sonicwall TZ 170 that I have connected to my internal network to separate 2 networks from each other. I connected the WAN port of the TZ170 to my main network with an address of 192.168.1.29 with the gateway of the Internet router (DHCP to test) which is the sub net for my main network. I then connected the 2nd network to one of the lan ports of thr TZ 170 with an IP of 10.10.10.1. I connected a computer to one of the other Lan ports and I am able to get to all the computers on the 192.168.1 side. The problem is I can not get to the 10.10.10 side from the 192.168.1 side. I have setup a rule to allow all wan to lan, still not working.
