I have a new, out of the box Sonicwall Tz105 firewall that I can't log into the UTM (management host). It's on a network behind a Netopia router running in bridge mode. The old Sonicwall it replaces was set to enable DHCP and we have fixed IP addresses on the network. When I type the gateway address into the browser shouldn't it find the Sonicwall? I've checked the connections and power cycled both the router and the firewall. Any suggestions are welcome.
