Translations:IPsec L2TP VPN server/211/en

As of Android 12, Android no longer supports IPsec/L2TP. Like Windows, Android won't offer anything stronger then modp1024, so strongSwan config has an added proposal of aes128-sha1-modp1024. This works even on very old version of Android (at least 4.2). If there are no Android client or other legacy clients (see Windows above), the may be removed or adjusted.
