Давно не приходилось работать с микротиком, уже подзабыл нюансы.

Помогите проверить и поправить конфигурацию.

 

Маршрутизатор RB2011UAS.

Порты eth1-eth5 - локальная сеть, соединены в бридж (у меня были сомнения в нормальной работе свитчипа).

Порт eth6 - провайдер1, дает доступ к локальным ресурсам (DHCP) и в интернет (PPPoE).

Порт eth7 - провайдер2, дает доступ в интернет (PPPoE).

Порты eth8, eth9 - не используются.

Порт eth10 - пока не используется, в дальнейшем будет отдельная сеть, на интерфейсе будет работать PPPoE-сервер.

 

Конфигурация примерно такая:

/ip pool add name=pool-lan ranges=192.168.48.0/24
/ip pool add name=dhcp-lan ranges=192.168.48.1-192.168.48.99

/interface bridge port
add bridge=bridge-lan interface=eth1
add bridge=bridge-lan interface=eth2

/ip dhcp-client add add-default-route=no dhcp-options=hostname,clientid disabled=no interface=eth6 use-peer-dns=no use-peer-ntp=no

/ip dns set allow-remote-requests=yes
/ip route add distance=1 dst-address=10.1.0.0/16 gateway=10.0.0.1

 

Настройки фаервола сделал такие:

/ip firewall address-list
