By default, `kvmd-otgnet` will configure network connection between Pi-KVM and the server host only. The server host will not be able to reach other hosts beyond Pi-KVM. If the full network access is required from the server host through the USB-Ethernet feature (access all hosts Pi-KVM can access), additional settings are needed in `/etc/kvmd/override.yaml`. By default, `kvmd-otgnet` will configure network connection between Pi-KVM and the server host only. The server host will not be able to reach other hosts beyond Pi-KVM. If the full network access is required from the server host through the USB-Ethernet feature (access all hosts Pi-KVM can access), additional settings are needed in `/etc/kvmd/override.yaml`.
1. Add network interface to forward requests to (default gateway) by adding a line `forward_iface: <interface name>` under `firewall:`. Typically it would be `eth0` if the built-in ethernet port is used:: 1. Run `echo "net.ipv4.ip_forward = 1" > /etc/sysctl.d/99-kvmd-extra.conf`.
2. Add network interface to forward requests to (default gateway) by adding a line `forward_iface: <interface name>` under `firewall:`. Typically it would be `eth0` if the built-in ethernet port is used::
```yaml ```yaml
otgnet: otgnet:
firewall: firewall:
allow_tcp: [80, 443]
forward_iface: eth0 forward_iface: eth0
``` ```
2. Add DNS server to provide host name resolution service. For example, adding `8.8.8.8` as DNS server requires addition of `dnsmasq` dhcp options. This can be done by adding following lines to `/etc/kvmd/override.yaml`: 3. Add DNS server to provide host name resolution service.
