Sonicwall blocking access to router

Hi all,

Just configured a Sonicwall TZ 180, my first with no previous experience.

All seems fine, then I notice that the Wireless isn't working. (Our router has built in wireless) I can't ping the router address either or gain access to the interface.

Router isn't acting as DHCP, server does that. But it is functioning as there is internet activity.

I can't seem to find anything within the Sonicwall interface, can anyone help?

I take it you are set up like this....

Internets-->Router(Wireless)-->Sonicwall-->LAN

Or am I barking up the wrong tree?

You might want this under "security" as well, mr. moderator :)
