(tagged) VLAN with only one NIC ?

Hello there,

is it possible to create 2 VLANs on one NIC, which is already in use (webadmin, port 4444)?

I'm using a small Box from Zotac (via dualcore, 4gb), which works very well.
Now i want to use a hp procuve switch with 2 VLANs, one multihomed port which is used by the astaro.

i Think i have to use an unused nic, right?
So can i realize a VLAN-Setup with only one nic (onboard)?

Thx in advance,

Manuel
