Roadwarrior <b>carol</b> proposes to gateway <b>moon</b> the cipher suite
<b>AES_CTR_128</b> both for IKE and ESP by defining <b>ike=aes128ctr-aesxcbc-modp2048</b>
and <b>esp=aes128ctr-aesxcbc-modp2048</b> in ipsec.conf, respectively.
A ping from <b>carol</b> to <b>alice</b> successfully checks the established tunnel.
