# Vlan ACL

🧭 Работаем внутри сети Headquarter, в частности на коммутаторе <kbd>HQ-SWITCH</kbd>, компьютерах и `HQ-MGMT`.&#x20;

🔧 Создаём VLAN Access Map на коммутаторе <kbd>HQ-SWITCH</kbd> для фильтрации проходящего трафика

```
ip access-list extended ACL_GW_ICMP
  permit icmp any host 172.16.1.254
!
ip access-list extended ACL_ANY_ICMP
  permit icmp any any
!
ip access-list extended ACL_ANY_RDP
  permit tcp any any eq 3389
!
ip access-list extended ACL_ANY_IP
  permit ip any any

vlan access-map VLAN_ACL 10
  map ip address ACL_GW_ICMP
  action forward
vlan access-map VLAN_ACL 20
  map ip address ACL_ANY_ICMP
  action drop
vlan access-map VLAN_ACL 30
  map ip address ACL_ANY_RDP
  action drop
vlan access-map VLAN_ACL 40
  map ip address ACL_ANY_IP
  action forward
!
vlan filter VLAN_ACL vlan-list 1
```

🐧 Пробуем с машины <kbd>HQ-MGMT</kbd> пропинговать все хосты в сети

* [x] ping 172.16.1.254
* [x] ping 172.16.1.10
* [x] ping 172.16.1.101
* [x] ping 172.16.1.102
* [x] ping 172.16.1.103

🐧Пробуем с машины <kbd>HQ-MGMT</kbd> проверить подключение по TCP/3389

```bash
nc -zv 172.16.1.10 3389
```
