Corporate VPN service with separate nets for different users/groups
Hi

We are going to host some services for customers with separate private networks for each customer. Each customer will need one or more users.

I have to put up a VPN solution, and I would like to use something that will work on "any" platform, easily, without too much installation/configuration. I feel PPTP is a good option since the "agent" is included on most platforms. We have a firewall/router on a Debian Linux server, and I'd like to extend it's services to include the VPN service. It has access to all nets, so it should be easier to get that to work.

My firewall/router has four interfaces, but only three of concern. eth0 is the outside, eth1 is the inside and eth2 is DMZ. I use proxyarp to get traffic from eth0 to eth2, with iptables filtering. eth1 has three internal nets in the 192.168.* series. The new nets I want to use for customers will be separate VLAN's on that interface with 10.20.x.* addresses. The firewall/router will of course have an IP in each of these (typically .1).

The big question is how to set this up? Can pptpd be used? Should this be done on a separate server?

fruadm

fruadm(1M)						  System Administration Commands						fruadm(1M)

NAME

       fruadm - prints and updates customer data associated with FRUs

SYNOPSIS

       /usr/platform/sun4u/sbin/fruadm

       /usr/platform/sun4u/sbin/fruadm -l

       /usr/platform/sun4u/sbin/fruadm [-r] path [text]

DESCRIPTION

       fruadm prints or sets the customer data for Field-Replaceable Units (FRUs).

       Without	arguments,  fruadm prints the paths of all FRU ID-capable FRUs (containers) in the system, along with the contents of the customer
       data record, if present, for each such FRU; for FRUs without customer data, fruadm prints only the container's path.

	Only a privileged user can create or update data in containers. The privileges required to perform these  write  operations  are  hardware
       dependent. Typically, a default system configuration restricts write operations to the superuser or to the platform-administrator user.

OPTIONS

       The following options are supported:

       -l	       List the system's frutree paths.

       -r	       Recursively display or update the data for all containers rooted at the argument path.

OPERANDS

       The following operands are supported:

       path		       A full or partial system frutree path for or under which to print or set the customer data. The first field of each
			       line of output of fruadm -l gives the valid full frutree paths for the system.

			       Paths can include shell meta-characters; such paths should be quoted appropriately for the user's shell.  For  par-
			       tial paths, the first matching full path is selected for display or update. Without the -r option, the path must be
			       that of a container; with the -r option, all containers (if any) under path will be selected.

       text		       Up to 80 characters of text set as the customer data. If the text contains white space or shell metacharacters,	it
			       should be quoted appropriately for the user's shell.

EXAMPLES

       Example 1: Displaying All Customer Data

       The  following  example prints all customer data available from FRUs on the system. For containers with no customer data, only the contain-
       ers' paths will be listed.

       example% fruadm

       Example 2: Displaying Customer Data For a Single FRU

       The following command prints the customer data, if present, for the specified FRU:

       example% fruadm /frutree/chassis/system-board

       Example 3: Displaying Customer Data For a Single FRU

       The following command prints the customer data, if present, for the first mem-module found:

       example% fruadm mem-module

       Example 4:  Setting Customer Data

       The following example sets the customer data for a FRU:

       example# fruadm system-board 'Asset Tag 123456'

       Example 5: Setting Customer Data

       The following command sets the customer data for all FRUs under chassis:

       example# fruadm -r /frutree/chassis "Property of XYZ, Inc."

EXIT STATUS

       The following exit values are returned:

       0	Successful completion.

       >0	An error occurred.
