ACX1100 uses your home network’s VLAN 13 as its WAN (internet access). VLAN 13 is also connected to a GNS3 virtual machine for future use.
- Logical Router Core (LRC): Only logical system directly connected to the ACX1100; serves as the core router. All other logical systems use it as a central “hop” to the rest of the network.
- Logical Router 1 (LR1): Stand-alone logical system.
- Logical Router 2 (LR2): Stand-alone logical system.
- Logical Router 3 (LR3): Stand-alone logical system with an extra port used for connection to an external ARM64 SBC running FRR.
Each node has an additional /32 loopback address.
ACX1100 will provide internet/home-network access via source NAT to all logical systems and their networks using the NAT pool 172.20.13.200–172.20.13.205.
