PureVPN IKEv2 mikrotik

[xheiko]

Пытаюсь подружить домашний mikrotik 7.2.1 c PureVPN по протоколу IKEv2. VPN по этому протоколу отлично работает с одного из компа внутри от Windows 11 и StrongSwan под Ubuntu. Цель для части адресов внутренней сети пустить весь трафик через PureVPN.

За основу был взята растиражированная всем VPN инструкция типа таких:
https://support.nordvpn.com/Connectivit ... ordVPN.htm
https://hide.me/ru/vpnsetup/mikrotik/ikev2/

С помощью нее удалось поднять IPsec Peer с проверенным сервером PureVPN

В Firewall никакой трафик не дропается.

Исходящий трафик прекрасно видно при логировании chain=srcnat

Счётчики IPSEC Peer тикают согласно объемам посылаемого трафика

Но весь обратный трафик из PureVPN где-то теряется в недрах mikrotik. Подскажите куда копать?

[hardrockbaby]

Fasttrack пробовали отключить?

Спасибо, за идею, но не помогло.
Поведение одинаковое. Исходящий из сети трафик вижу, обратный на WAN шифрованный есть, но он внутри ничего.

Для проверки отдать надо один днс в дхцп 1.1.1.1

Добрый день, а сертификат откуда брали? Можете поделиться как получить сертификат.
