# Hardware
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
metadata:
peerIP: LAN_IP
scope: global
spec:
asNumber: 64512
```
