lhg 60g anthenas

add two interfaces to your computer using network manager:

nmcli con add con-name eth0-mikrotik-default ifname eth0 type ethernet ipv4.method manual ipv4.address 192.168.88.100/24 autoconnect no
nmcli con add con-name eth0-mikrotik ifname eth0 type ethernet ipv4.method manual ipv4.address 192.168.35.100/24 autoconnect no

start eth0-mikrotik-default interface:

nmcli con up eth0-mikrotik-default

download latest winbox:

https://download.mikrotik.com/routeros/winbox/3.41/winbox64.exe

load winbox with wine:

wine winbox64.exe

when winbox loads on application top menu enable legacy mode:

tools / legacy mode

on first login to your router on anthena1 reset configuration:

remove this default configuration type "r" or hit any other key to continue

list interfaces mac addresses anthena1:

/interface print

create bridge interface anthena1:

/interface bridge add admin-mac=CHANGEME auto-mac=no comment=defconf name=bridge 

configure w60g interface anthena1:

/interface w60g set [ find ] disabled=no frequency=58320 mode=bridge name=wlan60-1 password=CHANGEME put-stations-in-bridge=bridge region=usa ssid=CHANGEME

create your security profile anthena1:

/interface wireless security-profiles set [ find default=yes ] authentication-types=wpa2-psk,wpa2-eap mode=dynamic-keys supplicant-identity=MikroTik wpa2-pre-shared-key=CHANGEME

add interfaces to bridge anthena1:

/interface bridge port
add bridge=bridge comment=defconf interface=ether1
add bridge=bridge comment=defconf interface=wlan60-1

set ip address to bridge interface anthena1:

/ip address add address=192.168.35.1/24 comment=defconf interface=bridge network=192.168.35.0

set gateway to anthena1:

/ip route add distance=1 gateway=192.168.35.100

set nameserers to anthena1:

/ip dns set servers=4.2.2.1,4.2.2.2

disable following services on anthena1:

/ip service
set telnet disabled=yes
set ftp disabled=yes
set www disabled=yes
set api disabled=yes
set api-ssl disabled=yes

change ssh port on anthena1:

/ip service set ssh port=2389

configure timezone on anthena1: /system clock set time-zone-name=America/Puerto_Rico update clock with ntp on anthena1:

/system ntp client set enabled=yes server-dns-names=us.pool.ntp.org

on your computer start eth0-mikrotik interface:

nmcli con up eth0-mikrotik

sharing my wireless internet to eth0 script:

cat > /usr/local/bin/sharenetwlan << EOF
#!/bin/bash
echo "1" > /proc/sys/net/ipv4/ip_forward
iptables -I INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -I FORWARD  -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -t nat -I POSTROUTING -s 192.168.35.0/24 -o wlan0 -j MASQUERADE
EOF

set permissions and run script:

chmod +x /usr/local/bin/sharenetwlan && /usr/local/bin/sharenetwlan

upgrade anthena1 firmware to latest version:

/system package update download

reboot anthena1:

/system reboot

connect to anthena2 using winbox:

wine winbox64.exe

on winbox application look for ip address:

192.168.88.3

wireguard

for wireguard support we need to switch to development channel:

/system package update set channel=development

then download the latest update:

/system package update download

reboot the router:

/system reboot

add wireguard interface:

/interface/wireguard add name=wg0 mtu=1420

add wireguard peer using server information:

/interface/wireguard/peers add endpoint=12.34.56.78:51820 persistent-keepalive=61 public-key="75VNV7HqFh+3QIT5OHZkcjWfbjx8tc6Ck62gZJT/KRA=" allowed-address="10.10.10.0/24" interface=wg0

add ip address to interface:

/ip/address add address=10.10.10.3/24 network=10.10.10.0 interface=wg0

add the following on the server configuration:

[Peer]
PublicKey=pEU+xV6YeWOKT34iECYDPRW99oLZKYodkUtjdIV8CwI=
AllowedIPs=10.10.10.3/32

restart wireguard on server:

systemctl restart wg-quick@wg0.service
