Wireguard doesn't seem to work on macppc 7.8

 >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`
