+# WireGuard with UI
+
+## Basic stuff
+
+### Install
+
+```shell
+helm install wg-easy ./helm --namespace wireguard --create-namespace
+```
+
+### Update
+
+```shell
+helm -n wireguard upgrade wg-easy ./helm/
+```
+
+### Check
+
+```shell
+kubectl -n wireguard get cm,pvc,pod,svc
+```
+
+### Tail Log
+
+```shell
+kubectl -n wireguard logs -f wg-easy-0
+```
+
+### Delete
+
+```shell
+kubectl delete ns wireguard
+```
+
+## K8s and unsafe option
+
+Config file on k8s host
+
+```shell
+sudo nano /var/snap/microk8s/current/args/kubelet
+```
+
+add `ipv4` and `ipv6` to be added to the end of the `kubelet` file.
+
+> --allowed-unsafe-sysctls=net.ipv4.ip_forward,net.ipv6.conf.all.forwarding
+
+## Changing IP
+
+these are recommended, as we use 8.0.0.0/8 for other things...
+
+```
+IPv4 172.16.0.0/24
+IPv6 fdb0::/112
+```
+
+> info: changing ip's, a restart of the pod is needed... for iptables and nat to change to new ip.
+
+## Problems with traffic
+
+This are more here for help if there is problem
+
+### Rout traffic
+
+Here is two ways of making the k8s server handle routing of traffic
+
+#### persistent iptables
+
+```shell
+sudo apt install iptables-persistent
+```
+
+- replace `<interface>` with your network card like `eth0`.
+- replace `<host-ipv4>` with ip like `10.8.0.0/24`.
+- replace `<host-ipv6>` with ip like `fdcc:ad94:bacf:61a4::cafe:0/112`.
+
+```shell
+sudo iptables -t nat -A POSTROUTING -s <host-ipv4> -o <interface> -j MASQUERADE
+sudo iptables -t nat -A POSTROUTING -s <host-ipv6> -o <interface> -j MASQUERADE
+```
+
+```shell
+sudo netfilter-persistent save
+```
+
+#### Systemd service
+
+create this file `/etc/systemd/system/wireguard-masquerade.service`
+
+```shell
+sudo nano /etc/systemd/system/wireguard-masquerade.service
+```
+
+Changes
+
+- replace `<interface>` with your network card like `eth0`.
+- replace `<host-ipv4>` with ip like `10.8.0.0/24`.
+- replace `<host-ipv6>` with ip like `fdcc:ad94:bacf:61a4::cafe:0/112`.
+
+```

+##### Enable
+
+```shell

+
+##### Start
+
+```shell

+
+### check things
+
+```shell
+kubectl -n wireguard exec -it pod/wg-easy-0 -- sysctl net.ipv4.ip_forward
+```
+
+```shell
+kubectl -n wireguard exec -it pod/wg-easy-0 -- sysctl net.ipv6.conf.all.forwarding
+```
