IPSEC与VLAN的通信问题（已解决）
公司有一个PIX515，级联一个3550,3550上分有四个VLAN，200段我只想要200.8作为网关，才能与外地的IPSEC通信。route inside 192.168.0.0 255.255.0.0 192.168.200.254 1(只有把这个命令去掉本地才能跟对端的IPSEC通信，但是外地的可以访问我们这边的资源,但是VLAN就无法访问外网了)
PIX515的配置：

end 没有人明白遇到过这个问题吗??? 找个问题好在了是route inside 192.168.0.0 255.255.0.0 192.168.200.254 包含了VPN对端的地址，
更改为下面三条route inside 192.168.201.0 255.255.255.0 192.168.200.254 1
route inside 192.168.202.0 255.255.255.0 192.168.200.254 1
route inside 192.168.203.0 255.255.255.0 192.168.200.254 1
