Здравтвуйте!

есть серая сеть, есть пул белых ip,

шлюз для них, авторизация серых

проиходит на другом железе, на

микротике нужно реализовать только

nat,

т.е. на входе 10.220.0.0/18, транслируюрся

в пул белых 188.х.х.0/24 и выходят

наружу через 141.х.х.х

 

 

вот конфиг, но что-то тут явно не так...
