Доброго!

Уважаемые, подскажите пожалуйста, где копать:

- VPN server: Cisco IOS Software, 2800 Software (C2800NM-ADVIPSERVICESK9-M), Version 12.4(11)XJ3, RELEASE SOFTWARE (fc1)
- VPN client: win 7

IPSEC + NAT-T работает (pre-shared key), а в PPP затык:

Попробуйте следующее

Доброго всем вечера.
Решилось апгрейдом иоса до c2800nm-advipservicesk9-mz.124-24.T.bin
Конфиг в порядке.

Всем спасибо за внимание и помощь!
