Assigning a specific IP address and Interface with MPD

[Jay Hall]

I have setup a VPN for the company I work for in which all of the remote 
offices connect to the Headquarters office using MPD.  And this works 
great until I have to re-establish the connections.

What I am trying to do, and maybe there is a better way, is to control 
what ng interface a client connects on so mpd can add routes for me 
based on the set iface route statement.

For example in my mpd.conf configuration file on the server I have the lines

pptp0:
	.....
	new -i ng0 pptp0 pptp0
	set ipcp 10.129.10.40/32 10.129.10.100/32
	set iface route 10.128.10.0/24
	...

pptp1:
	......
	new -i ng1 pptp1 pptp1
	set ipcp 10.129.10.40/32 10.129.10.101/32
	set iface route 10.129.10.0/24
	.....

On the client side (all are identical with the exception of the first 
ipcp address)
	........
	new -i ng0 vpn vpn
	set ipcp 10.129.10.100/32 10.129.10.40/32
	set iface route 10.129.10.0/24
	.........

In mpd.secret on the server I have (usernames and passwords have been 
changed)

user1	"user1"	10.129.10.100
user2	"user2:	10.129.10.101

I am seeing the correct IP addresses assigned as each user logs in, but 
they are not on the interface I would expect them to be on.

Is it possible to do this?  Or should I work on trying to add the routes 
as the interfaces come up based on the IP address they are assigned?

Thanks in advance for your assistance.
