[求助] ASA 8.42与ASA 8.02建立IPSec VPN后无法ping通

hibfnv

具体情况是这样：总部LAN A要建立与LAN B 及LAN C的IPSec VPN,同时LAN B, LAN C等均能互访。LAN A总部使用ASA 8.42版本5520防火墙，但分支均为ASA 8.02版本的5505防火墙。但目前VPN建立后，LAN B和LANC互访没有任何问题，但均无法访问LAN A. LAN配置使用IKEV1协议，而分支均使用ISAKMP协议。具体配置脚本如下：

请各位大神看看问题到底出在哪了，谢谢。内网中所有网段到A,B,C的防火墙的外网端口均能ping通。LAN C至LAN B内网能互通。

还是要仔细检查ASA1上的NAT配置，感觉有问题。但是没空细看。

非常感谢，确实是NAT上面的问题，目前仔细查询后发现是nat (inside) 0 access-list nat0没有更新，因为前面更新过access-list nat0，而后期没有应用nat (inside) 0 access-list nat0这条命令。

感谢回复，其实不需要使用set pfs也不影响，问题出在nat问题上。
