Bridge doesn't work on OpenBSD3.3 - configuration fault?
Hi all
I've a test environment as followed:
internet --- switch ------ <dhcp>OpenBSD3.3<192.168.0
|
------ <dhcp>SuSE Linux 8.2
I can ping 192.168.0.1 from the WinXP machine but not the Linux computer nor any ip on the internet.
Is there a mistake in the configuration?

ASKER CERTIFIED SOLUTION

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
But you can use OpenBSD with bridge and with or without IP address instead of "switch" on the left to filter more traffic (you need 4-port ethernet card in your box most likely).
