Raspberry Pi Wireless Router

Raspberry Pi wireless routers there are a lot of ways RaspberryPi can do. I will share my experience with you. As a wireless router, we need to provide dhcp and Wireless AP capabilities through the isc-dhcp-server and hostapd software, forwarding between NICS is directly implemented through iptables defining nat rules. Install dhcp service and ap hotspot service [python] apt-get install isc-dhcp-server apt-get install hostapd Modify/etc/network/interfaces in/etc/dhcp/dhcpd. conf Add/etc/hostapd. conf enables the NIC forwarding capability of the kernel and sets/etc/sysctl. [python] net. comment of ipv4.ip _ forward = 1 is removed. Modify the iptables nat rule [python] iptables-t nat-a postrouting-o eth0-j MASQUERADE to add the rule to the automatic start mode [python] iptables-save>/root/nat. rule New/etc/network/if-pre-up.d/iptables [python] #! /Bin/bash/sbin/iptables-restore </root/nat. rule or write the rule statement directly into the file. If your hostapd cannot work normally, hostapd does not support your Nic chip.
