学员提问:

服务器端用的ASA5520防火墙,
两条进线
建有ipsec vpn,

有三处办公地点 ,用cisco vpn client 拨入防火墙
1、移动光纤,通过TL-R402路由上网,网内只可一台机器拨入并且可以通讯,其它机器只能拨入,无法通讯
2、有线通宽带,通过TL-WR841N上网,所有机器都是只能拨入,无法通讯;
3、电信ADSL,通过锐捷NBR300路由上网,网内只可一台机器拨入并且可以通讯,其它机器只能拨入,无法通讯。

有高手指明查找原因方向

捷盈讲师及学员解答:

1、ASA的VPN Client 是有数量许可的,你需要查询的你许可数。
2、排除许可证的问题后,在同一个局域网或不同的营运商网络中,Client 端拨入后,应该会按你的VPN SERVER的许可来进行网络的访问。
3、如果是一个局域网的所有网络不可以访问,怀疑是其代理上网的NAT设备或营运商限制了。
4、至如一个局域网内有拨入成功的,不可以拨入的,怀疑是客户端的设置问题。
5、拨入成功的用户,却无法访问你的相关服务,请检查VPN SERVER端的ACL 设置。
