openswan ipsec.conf ike加密方式twofish/blowfish配置實現
新裝的Openswan U2.4.6 下 ipsec.conf
ike 加密方式為blowfish或twofish vpn不能成功協商起來，為des、3des都可以成功協商
想知道有什麼辦法可以解決ike的加密方式為blowfish或twofish，然後成功協商，謝謝！
《解決方案》
Openswan U2.4.6 和誰建立呢?
是不是對端不支持

是兩一樣配置的debian系統，ipsec.conf配置如下：

ike的加密演算法為：aes、3des時vpn能協商起來，現在我想ike的加密演算法用blowfish或twofish實現。
