Hi Thomas, Thanks for the feedback. I basically need a route to the peer. When the IP address is configured with a peer, the kernel adds an implicit route to it. I was hoping to achieve the same with NM. As a workaround, I explicitly set a manual route to the peer and it works. But this is just a ... workaround and I was hoping there was a cleaner way to do this. Anyway, before initially posting to the list, I had a quick look at the NM sources. It seemed to me that there's at least partial support for the PTP address, because: * NMPlatformIP4Address contains a peer_address field which, according to the comment in src/platform/nm-platform.h (where the actual struct is defined) seems to be the right thing. * This field seems to be handled down the path of nm_ip4_config_commit nm_platform_ip4_address_sync, nm_platform_ip4_address_add, ip4_address_add and _nl_msg_new_address. However, I'm new to the NM code base and I may very well be misreading it. Besides, the path that I highlighted only deals with NM to kernel sync, but doesn't say anything about the NM config and D-Bus side. In any case, I thought I was better off asking around than reading and trying to understand more of the code :) Thanks, Radu _______________________________________________ networkmanager-list mailing list [email protected] https://mail.gnome.org/mailman/listinfo/networkmanager-list
