Sorry to top post, but I've found that my network cards don't like frames > 1500, and so I've had to set the MTU on the vlan-encapsulation devices to something lower (I cba to find out how big a VLAN header is, so I just set it to 1400). I found that before I adjusted the MTU, small traffic (like pings) would get through, presumably because they were < MTU in size, but larger packets/frames would disappear. I hope this helps, Lee Causier Undergraduate (BSc Computer Science @ le.ac.uk, Year 1) On 11/19/05, Greg Brackley <[EMAIL PROTECTED]> wrote: > I'm trying to get a bridging and VLAN working together with an unexpected > lack of success.
