Hi,
We are Hoster.BG, a Bulgarian hosting company. A customer of ours wants to use ISPmanager on a dedicated server; he already has a license, but there are some questions that have arisen regarding the IP address that the license is issued to.
Our network infrastructure is somewhat peculiar, involving several VLANs, several network blocks, and a firewall doing static NAT for customer servers. As a consequence, in the default setup our servers do NOT have an interface configured with the "external"/"real" IP address that the world will see. It turns out that this won't allow the ISPmanager configuration to complete.
We have two questions regarding this matter. First, is it possible (and a "no, this is not our policy" answer is quite acceptable) for ISPmanager to be configured without the licensed IP address being actually present on a network interface on the server? This would be enough to support an IP address check done at a central licensing server - it would receive the connection from the correct address, and the address will be allocated only to this machine in our setup. We can see some arguments against such a choice, so a negative answer here would be quite acceptable, and we shall find a way to bring up the address on the server itself.
Second,
the ISPmanager installation guide contains the following section:
Quote:
|
IP-address licensed by ISPmanager control panel must be the first one in the IP-addresses list which ifconfig returns. That means the license is not valid for the main address aliases.
|
Does this really mean the first address returned by ifconfig at all, or does it mean that the address should be the first address on any interface? Our servers have various interfaces (Ethernet bonding, loopback, vlan, etc.), so we cannot guarantee that the licensed IP address will be configured on the very first interface returned by ifconfig. In fact, since the configured address might be on an ethX interface, and the "real" server connection will be through a bondX interface, it is virtually certain that ifconfig will report the bondX interface first. The configured address shall still be the first on *its own* interface - will this be acceptable?
Thanks in advance for your time, and for developing ISPmanager!
G'luck,
