Stearns > Niwot Networks, Inc. > Longmont, CO Well, I figured-out my problem...it was a bad ethernet card. I recently bought 2 D-Link DFE-530TX+ (listed in the supported section), I already have an ethernet card that worked in the computer I am using for FreeBSD 5.0, so I just opened up one of the D-Link cards to use. The initial tests were just to give it an address and ping it. Well, standard ping packet size for windows is 32, and 64 for Linux and FreeBSD (and I assume most other most if not all UNIX type platforms). Well the card seemed to work fine for this test. So I setup the 2 ether cards on the FreeBSD computer for bridge mode so we could use DummyNet. Again, I could ping through the bridge to another computer. But when it can down to transferring data/accessing other computers it wouldn't work...made me feel that I didn't setup the bridge correctly. Chris J. Stearns Niwot Networks, Inc. Longmont, CO
