LWIP如何配置多台不同IP的服务器进行连接？

Question

#define DEST_IP_ADDR0      192
#define DEST_IP_ADDR1      168
#define DEST_IP_ADDR2      0
#define DEST_IP_ADDR3      200
IP4_ADDR(&server_ip, DEST_IP_ADDR0,DEST_IP_ADDR1,DEST_IP_ADDR2,DEST_IP_ADDR3);

原代码中只有主机的static IP可以成功连接到192.168.0.200。 现在我希望任何具有不同 IP 的主机都能够连接。 How to achieve it, or only open one IP segment, only the static IP is 192.168.0.0- The host of 192.168.0.255 can only connect, how to modify the code to achieve it?

这是TCPclient.c的代码

#include "lwip/ip.h"
#include "lwip/tcp.h"
#include "lwip/init.h"
#include "netif/etharp.h"

#include "lwip/pbuf.h"
#include <stdio.h>

#include "main.h"
#include "tcpclient.h"
#define DEST_IP_ADDR0      192
#define DEST_IP_ADDR1      168
#define DEST_IP_ADDR2      0
#define DEST_IP_ADDR3      200
#define DEST_PORT      5001
#define UDP_SERVER_PORT     5002
#define UDP_CLIENT_PORT     5002
#define LOCAL_PORT     5001
