<message>Update documentation and scripts to include configuration for extra LAN IPs on eth1 and VLAN interface eth1.40, allowing the LXC to serve multiple subnets and provide NAT for internet access. Modify nftables NAT configuration to accommodate these changes and ensure proper DHCP and DNS setup on eth1. This improves the overall network boot functionality and user experience for the CM4 eMMC provisioning service.

# LXC config (network boot: eth1 = LAN, eth0 = WAN)
|
||
|
||
Config files for the **provisioning LXC** when using **eth1** as a provisioning LAN (DHCP + TFTP for network boot, NAT for internet).
|
||
|
||
**LAN subnet:** When you deploy with `DEPLOY_LXC_LAN_SUBNET` (e.g. `10.100.1.1/24`), the deploy script writes `/opt/cm4-provisioning/lan-subnet.conf` inside the LXC with `LAN_GW`, `LAN_CIDR`, and `DHCP_RANGE_START`/`DHCP_RANGE_END`. The setup script and toggle script read this file so dnsmasq, NAT, and PXE options all use the same subnet. If the file is missing, defaults are `10.20.50.1/24` and `10.20.50.100`–`10.20.50.200`.
|
||
|
||
| File | Purpose |
|
||
|------|--------|
|
||
| **dnsmasq-network-boot.conf** | Template: dnsmasq DHCP + TFTP on eth1. Setup script writes `/etc/dnsmasq.d/network-boot.conf` using values from `lan-subnet.conf`. |
|
||
| **nft-nat-lan.conf** | Template: nftables NAT for LAN→WAN (primary + extra subnets + VLAN 40). Setup script writes `/etc/nftables.d/nat-lan.conf`. |
|
||
| **70-cm4-extra-lan** | Extra LAN IPs on eth1 (192.168.30.1, 192.168.127.1) and VLAN eth1.40 (192.168.0.1/24). Installed to `/etc/network/interfaces.d/` by setup script. |
|
||
| **toggle-network-boot-dhcp.sh** | Enable/disable PXE (TFTP) on the LXC; copied to `/opt/cm4-provisioning/` by setup script. |
|
||
|
||
Setup is done by running (from your machine):
|
||
|
||
```bash
|
||
./emmc-provisioning/scripts/setup-network-boot-on-lxc.sh root@<LXC-IP>
|
||
```
