Your reply inspired me to google 802.1Q and ESXi, and I found a document describing different VLAN solutions on ESXi (http://www.vmware.com/pdf/esx3_vlan_wp.pdf). In this document it says that to make guest tagging work I have to set the VLAN ID of the port group on the virtual switch to 4095. After I did this, the above configuration works. > Regards, > > Mike Regards, Sebastiaan [-- Attachment #2 --] 0 *H 01 0 + 0 *H Q00lS| 6$1-~j0 *H 0b1 0 UZA1%0#U Thawte Consulting (Pty) Ltd.1,0*U#Thawte Personal Freemail Issuing CA0 080630135157Z 090630135157Z0h10Uvan Erk10U* Sebastiaan10USebastiaan van Erk1"0 *H sebster@sebster.com0"0 *H 0 Va\bEnݚa<M8ʄ^tv>x73bohi2oqS_¶Bm^p* I x"9 pt!j ar#)n)^?
