Question : Sonicwall rule to block DHCP traffic between two site-to-site

I have two remote sites with their own DHCP servers connected with SW TZ210 and Pro2040. How to create a rule to block DHCP traffic between the two site? Right now all traffic is allowed between both sites

Answer : Sonicwall rule to block DHCP traffic between two site-to-site

are you actually seeing DHCP traffic going between the site?  DHCP is a layer 2 protocol and most routers do not route layer 2 by default. So unless you specifically enabled layer 2 routing or you are bridging the two networks, so that they are both on the same subnet, then I would not have thought DHCP would be going between the two sites.
