I cannot see how this setup would work. Host 2 will be sending 802.11Q
encapsulated packets, but host 1 will not be expecting that so it will
ignore them. This would lead to the exact results you are seeing.
So to counter your subject line, I would say vlan *is* tagging packets,
it's just that one host is not expecting tagged packets.
You will need to set up vlan 10 on host 1 and assing 10.100.110.68 to
eth1.10 for it to receive packets.
>root@host1:~# tcpdump -vv -i eth1 -s 1500 ether proto not 0x88cc
Try running that tcpdump command with "-e" to show link level headers.
Perhaps that will show the VLAN tag on the packet.
