sslvpn contextip-route匹配机制

1.2  配置需求及实现的效果

V7防火墙设备作为出口设备，外网PC通过inode软件拨SSLVPN，认证成功后可以访问内网的资源。User1可以获取获取10.10.10.0/24网段的地址，访问192.168.10.0/24资源, User1可以获取获取20.20.20.0/24网段的地址，访问192.168.20.0/24资源,IP地址及接口规划如下表所示：

1 配置步骤

1.1  防火墙上网配置

防火墙上网配置请参考“2.2.2 防火墙外网使用固定IP地址上网配置方法”进行配置，本文只针对SSLVPN配置进行介绍。     

1.2  配置SSL VPN网关

#SSLVPN网关IP地址填写防火墙1口地址222.1.1.1.00，端口号修改为4433，缺省端口为443，443端口和https端口冲突，然后使能网关配置。

<H3C>sys

[H3C]sslvpn gateway SSLVPNGW

[H3C-sslvpn-gateway-SSLVPNGW]ip address 222.1.1.100 port 4433

[H3C-sslvpn-gateway-SSLVPNGW]service enable

[H3C-sslvpn-gateway-SSLVPNGW]quit

#创建SSL VPN AC接口1,配置接口IP为10.10.10.1/24

[H3C]interface SSLVPN-AC 1

[H3C-SSLVPN-AC1]ip address 10.10.10.1 255.255.255.0

[H3C-SSLVPN-AC1]ip address 20.20.20.1 255.255.255.0 sub

[H3C-SSLVPN-AC1]quit

 #创建地址池名称为“SSLPOOL1”，指定IP地址范围为10.10.10.2——10.10.10.254

[H3C]sslvpn ip address-pool SSLPOOL 10.10.10.2 10.10.10.254

 #创建地址池名称为“SSLPOOL2”，指定IP地址范围为20.20.20.2——20.20.20.254

sslvpn ip address-pool SSLPOOL2 20.20.20.2 20.20.20.254

 #创建ACL 3998，允许SSL VPN用户访问的内网资源192.168.20.0/24网段

[H3C]acl advanced 3998

[H3C-acl-ipv4-adv-3998]rule permit ip destination 192.168.20.0 0.0.0.255

[H3C-acl-ipv4-adv-3998]quit

 #创建ACL 3999，允许SSL VPN用户访问的内网资源192.168.10.0/24网段

[H3C]acl advanced 3999

[H3C-acl-ipv4-adv-3999]rule permit ip destination 192.168.10.0 0.0.0.255

[H3C-acl-ipv4-adv-3999]quit

1.3  配置SSL VPN实例

# 配置SSL VPN访问实例“SSLVPNSL”引用SSL VPN网关“SSLVPNGW”

 [H3C] sslvpn context SSLVPN

 [H3C-sslvpn-context-SSLVPN]gateway SSLVPNGW

#引用SSL VPN接口1

 [H3C-sslvpn-context-SSLVPN] ip-tunnel interface SSLVPN-AC1

#引用SSL VPN地址池，掩码和dns

 [H3C-sslvpn-context-SSLVPN]ip-tunnel address-pool SSLPOOL mask 255.255.255.0

 [H3C-sslvpn-context-SSLVPN]ip-tunnel dns-server primary 114.114.114.114

#创建路由列表“NEIWANG1”，添加路由表项192.168.10.0/24

 [H3C-sslvpn-context-SSLVPN] ip-route-list NEIWANG1

 [H3C-sslvpn-context-SSLVPN-route-list-NEIWANG1] include 192.168.10.0 255.255.255.0

#创建路由列表“NEIWANG2”，添加路由表项192.168.20.0/24

 [H3C-sslvpn-context-SSLVPN] ip-route-list NEIWANG2

 [H3C-sslvpn-context-SSLVPN-route-list-NEIWANG2] include 192.168.20.0 255.255.255.0

# 创建SSL VPN策略组“SSLVPNZIYUAN”，引用路由列表“NEIWANG1”，配置ACL限制，只有通过ACL检查的报文才可以访问IP资源

[H3C-sslvpn-context-SSLVPN] policy-group SSLVPNZIYUANGROUP1

[H3C-sslvpn-context-SSLVPN-policy-group-SSLVPNZIYUAN]filter ip-tunnel acl 3999

[H3C-sslvpn-context-SSLVPN-policy-group-SSLVPNZIYUAN]ip-tunnel access-route ip-route-list NEIWANG1

# 创建SSL VPN策略组“SSLVPNZIYUAN”，引用路由列表“NEIWANG2”，配置ACL限制，只有通过ACL检查的报文才可以访问IP资源

[H3C-sslvpn-context-SSLVPN] policy-group SSLVPNZIYUANGROUP2

[H3C-sslvpn-context-SSLVPN-policy-group-SSLVPNZIYUAN]filter ip-tunnel acl 3998

[H3C-sslvpn-context-SSLVPN-policy-group-SSLVPNZIYUAN]ip-tunnel access-route ip-route-list NEIWANG2

[H3C-sslvpn-context-SSLVPN-policy-group-SSLVPNZIYUAN]ip-tunnel address-pool SSLPOOL2 mask 255.255.255.0

        #启用该实例,用户绑定地址。

[H3C-sslvpn-context-SSLVPN-policy-group-SSLVPNZIYUAN]quit

[H3C-sslvpn-context-SSLVPN] user user2

[H3C-sslvpn-context-SSLVPN-user-user1] ip-tunnel bind address 20.20.20.2-20.20.20.10

[H3C-sslvpn-context-SSLVPN] service enable

[H3C-sslvpn-context-SSLVPN]quit

1.4  新建SSL VPN用户，关联SSLVPN资源组

#创建SSLVPN本地用户,配置用户名密码user1,服务类型sslvpn，引用之前创建的SSLVPN资源组1

[H3C]local-user user1 class network

[H3C-luser-network-user1]password simple user1

[H3C-luser-network-user1]service-type sslvpn

[H3C-luser-network-user1]authorization-attribute sslvpn-policy-group SSLVPNZIYUANGROUP1

[H3C-luser-network-user1]quit

[H3C-luser-network-user2]authorization-attribute sslvpn-policy-group SSLVPNZIYUANGROUP2

[H3C-luser-network-user1]quit

1.5  将SSL VPN端口加入安全域，放通对应安全策略

 #新建安全域，名称为“SSLVPN”，将SSL VPN端口1加入到安全域“SSLVPN”

 [H3C]security-zone name SSLVPN

 [H3C-security-zone-SSLVPN]import interface SSLVPN-AC1

 [H3C-security-zone-SSLVPN]quit

 #创建服务对象组，组名称为4433，匹配SSLVPN端

 [H3C]object-group service 4433

 [H3C-obj-grp-service-4433]service tcp destination eq 4433

 [H3C-obj-grp-service-4433]quit

#配置配置安全策略将Untrust到Local域目的端口为TCP4433端口放通

[H3C]security-policy ip

[H3C-security-policy-ip]rule 5 name Untrst-Local

[H3C-security-policy-ip-5-Untrst-Local]action pass

[H3C-security-policy-ip-5-Untrst-Local]source-zone Untrust

[H3C-security-policy-ip-5-Untrst-Local]destination-zone Local

[H3C-security-policy-ip-5-Untrst-Local]service 4433

[H3C-security-policy-ip-5-Untrst-Local]quit

#配置配置安全策略,放通源安全域为SSLVPN，目前安全域为“Trust”的数据流量

[H3C-security-policy-ip]rule 10 name SSLVPN-Trust

[H3C-security-policy-ip-10-SSLVPN-Trust] action pass

[H3C-security-policy-ip-10-SSLVPN-Trust] source-zone SSLVPN

[H3C-security-policy-ip-10-SSLVPN-Trust] destination-zone Trust

[H3C-security-policy-ip-10-SSLVPN-Trust]quit
