[PVE-User] Proxmox VE Networking issues

[Shain Miley]

I just re-enabled the dhcp server to double check and yes..when I tell 
windows to use DHCP it gets the following:

IP: 10.0.2.15
MN:255.255.255.0
GW:10.0.2.2

The networking works fine...again my issue at this point is that if I 
wanted to use Remote desktop or FTP into the server I would unable to do 
so without this server being assigned a real ip.

Shain

ps..where is the dhcp server info coming from..the host os?
