Roadwarrior carol proposes to gateway moon the ESP cipher suite
-AES_CBC_256 / AES_XCBC_96 by defining esp=aes256-aesxcbc-modp2048
-in ipsec.conf. The same cipher suite is used for IKE: ike=aes256-aesxcbc-modp2048.
+AES_CBC_128 / AES_XCBC_96 by defining esp=aes128-aesxcbc-modp2048!
+in ipsec.conf. The same cipher suite is used for IKE.
A ping from carol to alice successfully checks the established tunnel.
