Inter-VLAN communication on USG firewall

It’s time to check a firewall available in eNSP simulator. Today a simple task, just configuring inter-VLAN communication on Huawei USG5500.

Let’s look at the following topology:

Configuration roadmap:

  1. Configure L2 communication on the switch.
  2. As the switch is L2, configure subinterfaces on the firewall and enable L3 communication between different VLANs.
  3. Set IP addresses and gateways for all PCs.
  4. Create 2 security zones and configure interzone packet-filterfing to control traffic between VLANs.
  5. Security requirements for the network:
  • PC1 in VLAN100 and PC2 in VLAN200 can communicate each other.
  • PC3 in VLAN300 can access PC1 and PC2. PC1 and PC2 cannot access PC3.

VLAN, trunk, VLANIF (SVI) on Huawei switch

Today I want to show you:

  • How to configure VLANs
  • How to add interface to a VLAN
  • How to establish 802.1q trunk between two Ethernet switches and filter VLANs
  • How to configure VLANIF (VLAN interface or simply SVI).

Look at the following topology:

Let’s assume that we want to configure two switches, which are connected via Ethernet link. Both switches have PCs connected to them. We want to allow PC101 to be able to reach PC102 and PC201 to be able to reach PC202.To do so, we need to add two different VLANs, configure Ethernet Trunk between switches and add PCs to the correct VLAN.
