Configure the conflicting process to use a port other than 67 and configure DHCP to use port 67.DHCP uses UDP ports 67 and 68 to initiate communication between the client and server. If either of these ports is in use by another application, or the ports are otherwise reserved, DHCP will...
Solved: A TCP dump reveals, that the Dhcp server very often /allways replies to the client on port 67 when a proxy is involved. I need to get my head

UDP Helper功能不支持对DHCP报文的中继,即中继转发的UDP端口不能配置为67和68。如果要中继DHCP报文,需要使能DHCP Relay特性。 使能UDP Helper功能后默认配置了6个UDP端口号,此时执行ip udp-helper port port-number [ description description ]命令只能配置10个UDP端口号,当执行ip udp-helper port disable命令删除已...
端口:67 服务:Bootstrap Protocol Server 说明:通过DSL和Cable modem的防火墙常会看见大量发送到广播地址255.255.255.255的数据。这些机器在向DHCP服务器请求一个地址。HACKER常进入它们,分配一个地址把自己作为局部路由器而发起大量中间人(man-in-middle)攻击。客户端向68端口广播请求配置,服务器向67端口广播回应请求。

That is, the destination port number cannot be 67 or 68. To relay DHCP messages, enable the DHCP relay function. After UDP helper is enabled, six UDP port numbers are configured by default, and only a maximum of 10 UDP port numbers can be configured using the ip udp-helper port port-...
DHCP统一使用两个IANA分配的端口作为BOOTP:服务器端使用67/udp,客户端使用68/udp。 https 443 TCP 20=FTP Data,Amanda(传输数据) TCP 21=文件传输,(控制连接) TCP 22=安全服务(SSH) TCP 23=远程登录(Telnet),Tiny Telnet Server (= TTS) TCP 25=电子邮件(SMTP) ...
