I have bge(4) cards. This seems to be the correct one for me.
It still doesn't work. Here is the relevant lines from my rc.conf. I ma=
y=20
as well use the actual values. This is verbatim.
ifconfig_eth0=3D"-rxcsum -rxcsum6 -txcsum -txcsum6 -tso -vlanhwtag=20
-vlanhwtso up"
cloned_interfaces=3D"bridge0 bridge1"
ifconfig_bridge0_name=3D"public"
ifconfig_public=3D"addm eth0 up"
ifconfig_public_alias0=3D"inet 0x629e8b${me}/27"
ifconfig_public_alias0_ipv6=3D"inet6 2605:2600:1001::${me}/64"
defaultrouter=3D"98.158.139.94"
ipv6_defaultrouter=3D2605:2600:1001::1
Note that "me" is set to the hex value of the last octet, 65 in this case=
=2E
Here is what the interfaces look like:

In the VM I set the IP to 71 on the same network. Here is what that look=
s like:

ic 0=20

Everything looks correct but I can't even ping between the host and the V=
