A technician discovers that a SOHO firewall is blocking inbound traffic on UDP port 68, preventing workstations on the internal network from receiving critical configuration data. Which network service is being disrupted by this firewall rule?
Dynamic Host Configuration Protocol (DHCP) uses two UDP ports: the server listens on port 67, and clients listen on port 68. If UDP 68 is blocked, DHCP offer and acknowledgment messages cannot reach the clients, so they fail to obtain IP addresses automatically. DNS uses UDP/TCP 53, HTTPS uses TCP 443, and SMTP uses TCP 25, none of which are affected by blocking UDP 68.
