Currently I have 'eth0' and 'eth0:0'. 'Shortly', we'll be moving the office to another location (share office space with another company), where they have VLAN's. They have given me VLAN #20 and from what I can see (I'll be testing my setup later this week), everything should be ok. But what about the intranet server which have TWO addresses? I've tried 'eth0:0.20', 'eth0.20:0' (for the virtual interface) but neither worked...
