внешний адресс постоянно меняется, внутренний тоже.

почему это происходит и как с этим бороться?

[Ромка 567]

кто-то пытается заломиться по ssh и по ftp.

настроить allow address для ssh/winbox/ftp

[Enferno 163]

или смените порт ссш, а фтп вообще вырубить!

[dimka890 16]

ну то что пытаються заломиться то понятно, просто непонятно кто и почему? или типа кулхацкеры?

[Ромка 567]

скорее всего боты

[dimka890 16]

закрыл доступ по FTP вообще, по SSH оставил, но перенес на другой порт, посмотрим че будет.

кстати после таких приколов иногда даже инет падал
