Здравствуйте!
Имеется pix 515. Внешнему интерфейсу присвоен ip x.x.x.107. Соответственно в инет выходил под 107 адресом. почта приходит на x.x.x.106(это MX-запись).
После того как опубликовал ftp-сервер на ip x.x.x.108 исходящий трафик натится на 106 адрес,затем через некоторое время начинает натится на 108.После clear xlate все NAT возвращается на 106 адрес и т.д Соответственно некоторые сайты блокируют вход со 106 адреса,думая,что это внешний открытый почтовик.Как сделать NAT на 107 адрес?
Прилагаю конфиг
