>Synopsis: Wireguard doesn't seem to work on macppc (at least when
trying to connect to CGHMN)
>Category: powerpc
>Environment:
System : OpenBSD 7.8
Details : OpenBSD 7.8 (GENERIC) #13: Fri Oct 10 13:14:53
MDT 2025
[email protected]:/usr/src/sys/arch/macppc/compile/GENERIC
Architecture: OpenBSD.macppc
Machine : macppc
>Description:
I am trying to connect to a VPN (https://cghmn.org) through
wg-quick from a iBook G3 running OpenBSD 7.8, but it does not seem to work.
It first of all for some reason replaces the last field of
AllowedIps with `/0`, and also just doesn't work.
>How-To-Repeat:
- Write to /etc/wireguard/wg-conf.conf the following lines
(replacing the bracketed terms)
[Interface]
Address = <addres>/32
PrivateKey = <privatekey>
DNS = 100.64.12.2
MTU = 1300
[Peer]
PublicKey = k/QiJIbMakMKgTCHVt8/D+8k4DzRVM6U33F3gMZfRUg=
AllowedIPs = 100.64.0.0/10
Endpoint = us.wg.cghmn.org:42070
PersistentKeepalive = 15
PresharedKey = <presharedkey>
- Run `wg-quick up wg-conf`
