--- Comment #40 from Tom Jones <t...@freebsd.org> --- Some extra info from demido via irc https://termbin.com/et91 is my wireguard setup that works (but has tiny throughput down to wg client) including iperf tests from wg client to wg server over tunnel, wg client to wg server over inet, and wg server to wg client over tunnel. https://termbin.com/07dl is networking info on wg client. FIXED: i isolated the 'solution' to being adding 'hw.vtnet.csum_disable="1"' to /boot/loader.conf. nothing else needed, and download speed of freebsd (and debian) install isos from wg client became nearly as fast as wg server. this seems related but separate from similar suggestions of disabling tso and lro as i /only/ needed to disable csum. keywords: nat, checksum, vtnet. related bugs: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=235607, https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=263229, https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=165059, https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=259249, https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=170081 other links: https://lists.freebsd.org/pipermail/freebsd-questions/2021-January/292565.html, https://forums.freebsd.org/threads/wireguard-vpn-slow-speed.73490/page-2#post-584231, https://sourceopen.com/index.php/howto-fix-slow-networking-with-a-wireguard-server-in-a-freebsd-jail-on-a-vps-and-slow-downloads-in-a-jail-on-a-vps/, https://forums.freebsd.org/threads/nat-low-speed-outside-of-local-subnet.49498/, https://serverfault.com/questions/817664/slow-network-fixed-adding-hw-vtnet-csum-disable-1-what-are-the-posible-side-effe, https://imil.net/blog/posts/2019/freebsd-networking-issues-disable-offloading-and-checksum/, https://www.mail-archive.com/freebsd-jail@freebsd.org/msg03651.html, more https://search.brave.com/search?q=freebsd+nat+vtnet+disable+checksum -- You are receiving this mail because: You are the assignee for the bug.
