Tips

port forwarding

Port forwarding is two steps:

  1. redirect port from outside to internal (NAT)
  2. allow access from outside to inside via this port (firewall)

Contents of /etc/config/firewall

config redirect option name 'PassthroughformyServer' option src 'wan' option proto 'tcp' option src_dport '80' option dest_ip '192.168.1.100' option dest_port '80' option target 'DNAT' option dest 'lan' config rule option src 'wan' option proto 'tcp' option dest_port '80' option target 'ACCEPT'

Note: Proto can be 'tcp' OR 'tcpudp' OR 'udp'

reserved ip / static lease

Contents of /etc/config/dhcp

config host option ip 192.168.1.122 option mac c2:44:32:18:cd:ab option name reservedipcomputer

I tried to add this to the wiki, but someone (https://openwrt.org/docs/guide-user/base-system/dhcp_configuration?rev=1596434574) decided to replace my simple solution with an obfuscated one that requires uci commands. So instead, it will remain here. EDIT: I added it back. See how long that lasts...

openvpn

opkg install openvpn-openssl

Contents of /etc/config/openvpn

config openvpn 'custom_config' option config '/etc/openvpn/myconfigfile.ovpn'

And your .ovpn in /etc/openvpn/.

aliases

Put in /etc/profile. e.g.

Contents of /etc/profile
