# Using hyp with OpenWrt Wireguard
|
||
|
|
|
||
|
|
This example case is to deploy hypd on OpenWrt to open up access to the WireGuard VPN service.
|
||
|
|
|
||
|
|
hyp utilizes eBPF technology to ensure runtime overhead is extremely small (in a way, but in a way not). Most Linux distributions have support for this out of the box, however OpenWrt does not. OpenWrt has a very stripped down, purpose-configured kernel and does not have the requirements built in to run hyp.
|
||
|
|
|
||
|
|
The good news is, you can build OpenWrt yourself and configure it with the requirements. Follow the directions at this page: https://openwrt.org/docs/guide-developer/toolchain/use-buildsystem
|
||
|
|
|
||
|
|
When you run *make menuconfig*, make sure you check off *Enable additional BTF type information* which is also known as CONFIG_KERNEL_DEBUG_INFO_BTF. This is required to support eBPF CO:RE.
