How to impose the restriction that some users under the U1980 are only allowed to dial certain prefixes

Configure the USG2000&5000&6000 to allow only certain users to log in through Telnet in VTY mode as follows: Create a corresponding ACL to allow only packets from a specified source address and then apply this ACL to the VTY interface. The configuration example is as follows: [USG-1]acl 3999 [USG-1-acl-adv-3999]rule permit ip source 1.1.1.1 0 [USG-1-acl-adv-3999]rule deny ip source any [USG-1-acl-adv-3999]quit [USG-1]user-interface vty 0 4 [USG-1-ui-vty0-4]authentication-mode aaa [USG-1-ui-vty0-4]protocol inbound telnet [USG-1-ui-vty0-4]acl 3999 inbound

To configure an interface to allow access from certain IP addresses, configure an ACL to match the IP addresses, reference the ACL in a traffic policy, and apply the traffic policy to the interface. For example, to allow only the user with IP address 1.1.1.2 to access GE0/0/1, run the following commands: [HUAWEI] acl number 3030 [HUAWEI-acl-adv-3030] rule permit ip source 1.1.1.2 0 [HUAWEI-acl-adv-3030] quit [HUAWEI] acl number 3031 [HUAWEI-acl-adv-3031] rule permit ip [HUAWEI] traffic classifier test1 [HUAWEI-classifier-test1] if-match acl 3030 [HUAWEI] traffic classifier test2 [HUAWEI-classifier-test2] if-match acl 3031 [HUAWEI] traffic behavior test1 [HUAWEI-behavior-test1] permit [HUAWEI] traffic behavior test2 [HUAWEI-behavior-test2] deny [HUAWEI] traffic policy test [HUAWEI-trafficpolicy-test] classifier test1 behavior test1 [HUAWEI-trafficpolicy-test] classifier test2 behavior test2 [HUAWEI] interface gigabitethernet 0/0/1 [HUAWEI-GigabitEthernet0/0/1] traffic-policy test inbound

WLAN devices allow only some users to access the web page: When a WLAN device functions as an HTTPS server, you can configure an ACL on the device to allow only the specified clients to log in to it through HTTPS. This function improves system security. [Huawei] acl 2000 //Set the ACL number to 2000 for the HTTPS IPv4 server. [Huawei-acl-basic-2000] rule 1 permit source 10.1.1.1 0 //Allow only users on the network segment 10.1.1.1 to access the web page. [Huawei-acl-basic-2000] quit [Huawei] http acl 2000 //Configure the HTTP login restriction.

To allow only some users to call an intra-office number on the U1900, perform the following steps: Step 1 Configure the number as a prefix and define custom call right 1 for this prefix. config add prefix dn 90 callcategory basic callattribute inter cusattribute cus1 cldpredeal no Step 2 Select custom call right 1 for users who can call this number. Specifically, on the web management system of the U1900, choose User > SIP User > Service Configuration > Outgoing Call Right and select this custom call right.
