Hi.
My vmware2 use netgraph bridge to access the network. In 4.4 all work fine.
But after upgrade to 4.5 I got some trouble. I can't ping my FBSD box
under vmware, but all other boxes in network are reaching fine.
My configuration:
--------+
xl0 - 172.17.1.206/16 <--> 172.17/16 (DHCP server, Internet, etc)
|
FBSD 4.5|
+-----------------------------------------------------------+
vmnet1 - 172.17.240.241/16 <--> 172.17.5.121/16 (vmware2, win98se) |
--------------------------------------------------------------------+
Some usefull info:
Win98SE (guest OS) use DHCP server for assigning IP address, DNSes &
default gateway.
