- du hast dich bei deiner verschleierungsaktion vertan, und es wird doch ein /30er netz durchgeroutet
sollte ein overlay vorliegen- und damit meine ich, daß das tg eine grundverbindung aufbaut, über die dann ein pptp-tunnel für den eigentlichen traffic gelegt wird, dann inode ersuchen, dieses unnötige konstrukt zu beseitigen und direkt zu routen.
im notfall könnt ich dir im austausch ein vorkonfiguriertes ding zukommen lassen
