H3C防火墙F100-C-AI+导致佳能网络打印机无法扫描
- 0关注

问题描述：
网络结构如下：
目前导致的问题终端电脑远程调用佳能网络打印扫描功能，提示服务器无响应，无法使用。把防火墙绕开，佳能设备就可以正常使用，通过现场测试，把测试电脑直接连在核心交换机机20口，和打印机属于同一VLAN和同一网段，可以PING通，加载上防火墙，还是无法调用打印机服务。求大神提供解决方法？防火墙配置和交换机配置见附件TXT文档。
组网及组网描述：
边界设备：H3C-ER3100路由器
防火墙部署在路由器和交换机机中间，防火墙型号是：H3C-F100-C-AI
核心交换机型号：H3C-S5120-28P-LI

防火墙版本较早，是这个version 5.20, Release 2209P26，具体在哪操作？全通策略配置操作劳烦发下，我目前防火墙的配置没有任何安全策略，详细见配置如下：

设备防火墙功能就没开，默认是关闭的，这样的话就检查路由通不通就行了
路由是通着的，现在就是不能调用佳能设备的扫描服务，当把防火墙绕开时，终端互联网就不通了，但是佳能网络扫描服务正常了。
路由是通的指的是终端能ping通打印机？
对啊

您好，请知：
主要还是防火墙的问题，以下是防火墙上的部署要点，请参考：
1、防火墙上涉及到的物理端口需加入安全域并放通安全策略或域间策略。
2、以下是防火墙上域间策略放通的参考命令：
[SSL_VPN]acl basic 2001
[SSL_VPN-acl-ipv4-basic-2001]rule 0 permit source any
[SSL_VPN-acl-ipv4-basic-2001]quit
[SSL_VPN]
[SSL_VPN]zone-pair security source trust destination untrust
[SSL_VPN-zone-pair-security-Trust-Untrust]packet-filter 2001
[SSL_VPN-zone-pair-security-Trust-Untrust]quit
[SSL_VPN]
[SSL_VPN]zone-pair security source untrust destination trust
[SSL_VPN-zone-pair-security-Untrust-Trust]packet-filter 2001
[SSL_VPN-zone-pair-security-Untrust-Trust]quit
[SSL_VPN]
[SSL_VPN]zone-pair security source trust destination local
[SSL_VPN-zone-pair-security-Trust-Local]packet-filter 2001
[SSL_VPN-zone-pair-security-Trust-Local]quit
[SSL_VPN]
[SSL_VPN]zone-pair security source local destination trust
[SSL_VPN-zone-pair-security-Local-Trust]packet-filter 2001
[SSL_VPN-zone-pair-security-Local-Trust]quit
[SSL_VPN]
[SSL_VPN]zone-pair security source untrust destination local
[SSL_VPN-zone-pair-security-Untrust-Local]packet-filter 2001
[SSL_VPN-zone-pair-security-Untrust-Local]quit
[SSL_VPN]
[SSL_VPN]zone-pair security source local destination untrust
[SSL_VPN-zone-pair-security-Local-Untrust]packet-filter 2001
[SSL_VPN-zone-pair-security-Local-Untrust]quit
3、进一步检查下防火墙上的端口互联和路由配置，确保路由可达。

现在防火墙我通过配置查看，没有任何安全策略，加上防火墙默认配置，终端都是可以连接互联网，都是通的状态。当把防火墙断开时，所有终端就可以调用网络打印以及扫描服务了。
