Примечание 1:
Команда sysopt connection permit-ipsec нуждается в настройке.
Команда show running-config sysopt проверяет была ли она сконфигурирована.

Примечание 2:
Добавьте следующий листинг для опциональной настройки UDP транспорта.

group-policy clientgroup attributes
vpn-idle-timeout 20
ipsec-udp enable
ipsec-udp-port 10000
