While bare-metal Kubernetes clusters have no special hardware requirements (beyond the [min reqs](/bare-metal#requirements)), Typhoon does ensure certain router and server hardware integrates well with Kubernetes.

### Port Forwarding
|
||||
|
||||
Expose the [Ingress Controller](/addons/ingress#bare-metal) by adding `port-forward` rules that DNAT a port on the router's WAN interface to an internal IP and port. By convention, a public Ingress controller is assigned a fixed service IP like kube-dns (e.g. 10.3.0.12).

### BGP
|
||||
|
||||
Add the EdgeRouter as a global BGP peer for nodes in a Kubernetes cluster (requires Calico). Neighbors will exchange `podCIDR` routes and individual pods will become routeable on the LAN.
|
||||
|
||||
Configure node(s) as BGP neighbors.
|
||||
|
||||
```
|
||||
show protocols bgp 1
|
||||
set protocols bgp 1 parameters router-id LAN_IP
|
||||
set protocols bgp 1 neighbor NODE1_IP remote-as 64512
|
||||
set protocols bgp 1 neighbor NODE2_IP remote-as 64512
|
||||
set protocols bgp 1 neighbor NODE3_IP remote-as 64512
|
||||
```
|
||||
|
||||
View the neighbors and exchanged routes.
|
||||
|
||||
```
|
||||
show ip bgp neighbors
|
||||
show ip route bgp
|
||||
```
|
||||
|
||||
Be sure to register the peer by creating a Calico `bgpPeer` CRD with `kubectl apply`.
|
||||
|
||||
```
|
||||
apiVersion: v1
|
||||
kind: bgpPeer

||||
