is it veth pair interface, right? ok... and is 192.168.8.254 assigned to veth inside VE? > 08:16:19.401880 00:1b:d4:7e:76:2a > 01:00:0c:cc:cc:cd SNAP Unnumbered, ui, > Flags [Command], length 50 > 08:16:21.154240 IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from > 00:1b:d5:2c:bf:38, length 308 > 08:16:21.185096 IP 192.168.8.254.67 > 255.255.255.255.68: BOOTP/DHCP, Reply, > length 300 > 08:16:21.187344 arp who-has 192.168.9.254 tell 192.168.9.97 > > > HN: tcpdump -n -i br107 > 08:16:19.401880 00:1b:d4:7e:76:2a > 01:00:0c:cc:cc:cd SNAP Unnumbered, ui, > Flags [Command], length 50 > 08:16:21.154240 IP 0.0.0.0.68 > 255.255.255.255.67: BOOTP/DHCP, Request from > 00:1b:d5:2c:bf:38, length 308 > 08:16:21.185096 IP 192.168.8.254.67 > 255.255.255.255.68: BOOTP/DHCP, Reply, > length 300 > 08:16:21.187344 arp who-has 192.168.9.254 tell 192.168.9.97 > > and finally, from inside the vps: > VPS: tcpdump -n -i eth0 > 08:16:19.401886 00:1b:d4:7e:76:2a > 01:00:0c:cc:cc:cd SNAP Unnumbered, ui, > Flags [Command], length 50 > 08:16:21.185110 IP 192.168.8.254.67 > 255.255.255.255.68: BOOTP/DHCP, Reply, > length 300 > 08:16:21.187356 arp who-has 192.168.9.254 tell 192.168.9.97 > 08:16:21.188600 arp who-has 192.168.8.1 tell 192.168.9.97 I wonder why timestamp of Reply here is greater then timestamp in HN... Maybe... it was reply from someone else? This would make things logical - someone replies to DHCP requests and you see the reply only.
