Centos7 получить IP по DHCP и удалить шлюз.

[april22]

Здравствуйте !
Собственно вопрос в теме ...
На сервере есть две сетевые карты , и обе получают адреса по DHCP. На одной сетевой карте , надо получить адрес по DHCP и тут же как то удалить шлюз на этой карте.(прописать руками нельзя) Да так надо, для чего ?! НАДО. Может как то потом скриптом удалить , или еще как то.

Гуглил - ответа не нашел.

Никто не мешает при if-up запустить скрипт и херить ненужное)

Плюс правильный default gw можно сделать с большим весом.

[april22]

направление понятно - пойду почитаю че нибудь ..
был бы признателен если бы хоть какие то примеры

[Zavr2008]

Не проще накатить виртуалку с микротиком CHR и не паритца?)

[april22]

нет не проще ...

[Zavr2008]

Там просто у DHCP клиента галочка есть чтобы маршрутами не баловался девайс

Добавить DEFROUTE=no в конфигурацию интерфейса (/etc/sysconfig/network-scripts/ifcfg-?) ?
