That is DHCP request traffic from some other device on the WAN. In practice, most providers block this traffic from reaching you so that you don't cause a DoS against other hosts on the network by giving out random IP addresses that are not in the correct subnet for this network. If you have done of your own devices on the WAN side, then it is most likely that this is a normal DHCP request from one of them. Otherwise, your ISP is either very trusting of its users or has misconfigured something. Moshe
