[Bug 165059] vtnet(4): Networking breaks with a router using virtio net driver on KVM host
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=165059 --- Comment #28 from elico --- (In reply to elico from comment #27) OK so just to mention the NAT related documents are at: http://draft.scyphus.co.jp/freebsd/nat.html and ontop of Oracle Enterprise Linux 8 KVM host the issue exists on 12.3 the setup is very simple: * Alpine 3.16 with ip 192.168.111.1/24 gw 192.168.111.254 DNS 8.8.8.8 * FreeBSD 12.3 with two interfaces: vtnet0 192.168.110.1/24 GW 192.168.110.254 vtnet1 192.168.111.254/24 pf rules to nat on $ext_inf * VyOS 1.3.2 with two interfaces: eth0 192.168.122.183/24 GW 192.168.122.1 eth1: 192.168.110.254/24 ping from Alpine to 8.8.8.8 via FreeBSD (NAT) -> VyOS (NAT) = works (ICMP_ wget from Alpine to 8.8.8.8 via FreeBSD (NAT) -> VyOS (NAT) = doesn't work (TCP) When I am running the next on the vtnet0 and vtnet1 interfaces the TCP works: ifconfig vtnet0 -rxcsum ifconfig vtnet1 -rxcsum It was resolved long ago in OpenBSD so now there only should be a fix and a text. -- You are receiving this mail because: You are on the CC list for the bug.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=165059 --- Comment #27 from elico --- (In reply to Kubilay Kocak from comment #26) I will try to test later on. Since Ubuntu 14.04 is not supported anymore I will try to reproduce on later versions of Ubuntu 20.04/22.04 and Oracle Linux 8. I will try to verify with 12.3 and 12.4 -- You are receiving this mail because: You are on the CC list for the bug.
