XP 连接FOS 5.4/5.6/6.0版本的SSL VPN必失败，必须在XP和FGT分别进行相应的参数修改。
 
理论上来说官方新版本已经不再支持XP系统连接SSL VPN，V5.6以后的官方版本已经彻底去掉了SSL v3协议，因此如果FGT使用默认SSL VPN的配置，XP系统是没办法连接到SSL VPN的，但是如果由于业务原因一定要使用XP系统连接SSL VPN，那么需要从两方面修改设置才可以让XP成功连接到SSL VPN：
 XP方面的修改：
1.安装IE8-WindowsXP-x86-CHS.exe 浏览器 
IE8下载地址




 2.在浏览器“Internet选项”中开启TLS1.0协议




 FGT SSL VPN方面配置修改：
1.ssl vpn 下面开启TLS1.0协议（5.4.X中还可以开启SSL V3），并降低加密强度
2.在SSL VPN setting里面的config authentication-rule 将加密算法的长度调整为any长度，默认为大于等于168位
config vpn ssl settings
    set sslv3 enable             //默认disable，FOS 5.6之后彻底删除掉了ssl v3
    set tlsv1-0 enable       //默认disable
    set algorithm medium 或 set algorithm low // 默认为 HIGH，XP系统的加密强度最弱无法满足要求    config authentication-rule
        edit 1
            set groups "Guest-group"
            set portal "full-access"
            set cipher any       //默认为HIGH
        next
    end
end
 
 
 ---------------------------------------------------------------
----------------------------------------------------------------
完整的配置举例说明：
 
1.定义user和user-group，ssl vpn用户 资源的定义







2.新建内网网段IP地址对象，用于后续的SSL VPN隧道分割和策略调用




 
3.使用自带的full-access模板即可，开启隧道分割，选择内网网段IP地址对象，这就是内网资源的定义







 
4.配置SSL VPN的端口，关联ssl  vpn user-group资源和full-access内网资源







 
5.配置SSL  VPN的策略，注意源IP里面需要调用user-group，目的IP需要调用隧道分割网段，做一个用户组和资源组的相互关联



 
FortiGate的SSL VPN配置完毕，默认状态应该就是这样，这个时候会发现 WIN7 WIN10等下系统连接SSL VPN没有任何问题，但是XP系统则怎么样都无法连接上SSL VPN，具体有两种报错：

修改SSL VPN的配置：
FG100E4Q16003872 # config vpn  ssl settings
FG100E4Q16003872 (settings) # config authentication-rule
FG100E4Q16003872 (authentication-rule) # edit 1
FG100E4Q16003872 (1) # show
config authentication-rule
    edit 1
        set groups "SSL_VPN_User_Group"
        set portal "full-access"
    next
end
FG100E4Q16003872 (1) # show full-configuration
config authentication-rule
    edit 1
        set groups "SSL_VPN_User_Group"
        set portal "full-access"
        set realm ''
        set client-cert disable
        set cipher high   //默认为HIGH 需要168位及以上的加密算法，但是XP的加密算法不符合要求
        set auth any
    next
end
FG100E4Q16003872 (1) # set cipher
any       Any cipher strength.
high      High cipher strength (>= 168 bits).
medium    Medium cipher strength (>= 128 bits).
FG100E4Q16003872 (1) # set cipher any   //修改为any，接收DES等低位数加密算法
FG100E4Q16003872 (1) # end
FG100E4Q16003872 (settings) # end
 
总结修改的配置：
 FG100E4Q16003872 # config vpn ssl settings
FG100E4Q16003872 (settings) # show
config vpn ssl settings
    set tlsv1-0 enable
    set servercert "Fortinet_Factory"
    set algorithm medium
    set tunnel-ip-pools "SSLVPN_TUNNEL_ADDR1"
    set port 4443
    set source-interface "wan1"
    set source-address "all"
    set default-portal "full-access"
    config authentication-rule
        edit 1
            set groups "SSL_VPN_User_Group"
            set portal "full-access"
            set cipher any
        next
    end
end
 然后XP拨号就可以了：
