Networking issue part II
Static IP Networking
First create a DNS record for your new vserver that points to an available IP address.
debian in A 140.112.8.13
Then use this ip address in the build method. The VServer will bind this ip on host machine, so if you have enough IP, you can easily have VServer on the same subnet as host machine.
VLAN
VServer supports VLAN device, you can simply give a vlan interface name for a vserver.
Private IP Issue
If you have only one public IP address, you can use iptables to do SNAT(masq) and DNAT(port forwarding) for vservers.
More of Single IP Issue
If you want to have multiple vservers running apache, you can setup a web gateway, and use apache's rewrite or proxy module for reverse proxy, you can also use squid to do this.
Problematic Programs
There are some programs that require special rights (capabilities), and might not work inside a VServer by default. Usually you need to rebuild the program with the capability disabled to solve the problem./
