Доброго времени суток!
Есть: 2621XM (ниже  sh ver)
Не могу пробросить IPSec через NAT внутрь.
По докам с cisco.com версия 12.2
этого не умеет, рекомендовали обновить на более новую.
Следуя инструкциям залил во flash образ с ftp (copy ftp: flash:),
далее действовал инструкции с  cisco.com
Conf t -> no boot system -> boot system flash: c2600-\\\\\\
Далее ^Z -> write memory -> reload

После reload на этапе загрузки ошибка:
=========================================
program load complete, entry point: 0x80008000, size: 0x66ae10
Self decompressing the image : ###########################
##[OK]

  ID            MEMORY_REQ                 TYPE

                0X00211000 public particle pools

If any of the above Memory Requirements are
"UNKNOWN", you may be using an unsupported
configuration or there is a software problem and
system operation may be compromised.
Rounded IOMEM up to: 5Mb.

Using 15 percent iomem. [5Mb/32Mb]
Далее идет
%IPNAT-6-NAT_CREATED: Created ? тххххххххххххххххххххххххххххххх (много правил по НАТу)
и появляется следующее:
=========================================
%IPNAT-6-NAT_CREATED: Created ? //////////////////////////////////////////
%SYS-6-READ_BOOTFILE_FAIL: flash:c2600-io3-mz.123-19.bin File read failed -- Unknown error 0.

%SYS-6-BOOT_MESSAGES: Messages above this line are from the boot loader.
boot of "c2600-io3-mz.123-19.bin" using boot helper
"flash:c2600-io3-mz.122-13.T4.bin" failed
error returned: File read failed -- Unknown error 0
loadprog: error - on file open
boot: cannot load "c2600-io3-mz.123-19.bin"
=========================================
Такое впечатление, что криво залил образ во flash
После ошибки идет reload  и происходит загрузка старого образа 12.2

Уже второй день ничего не получается. Прошу доброго совета.
