CISCO\r\nThese are generally applicable to most (all?) CISCO firewalls: \r\nFirst you need to create an access list describing the traffic (X.X.X.X is the IP address of your mail server. Add more lines if you have more than one) \r\n\r\n\r\naccess-list acl_out permit tcp host X.X.X.X any eq 25\r\naccess-list acl_out deny tcp any any eq 25\r\n... any other outbound rules you may want go here ...\r\naccess-list acl_out permit ip any any\r\n\r\nThen you need to apply that access-list to the inside interface (because it is being checked on the inside before it goes out) \r\n\r\naccess-group acl_out in interface inside\r\n\r\n我的邮件服务器ip被cbl.abuseat.org列入黑名单了.\r\n网站提示,可以在路由器中这样设置,就是上述的CISCO设置,\r\n第一句这样理解吗?\r\n只允许外网访问内网该ip的25端口,也就只允许内网该ip的25端口可以向外发包吗?\r\n我始终没有明白配置的含义,所以导致我也不能配置好我的ar18-63-1. |
