Network Manager PPTP Incorrect Routes

[Garry T. Williams]

When I connect to my VPN using Network Manager, I end up with the wrong route table.  Here's what I start with:

Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
192.168.0.0     0.0.0.0         255.255.255.0   U         0 0          0 eth0
0.0.0.0         192.168.0.1     0.0.0.0         UG        0 0          0 eth0

After connecting, I get this:

Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
65.237.0.254    192.168.0.1     255.255.255.255 UGH       0 0          0 eth0
192.168.0.0     0.0.0.0         255.255.255.0   U         0 0          0 eth0
0.0.0.0         0.0.0.0         0.0.0.0         U         0 0          0 ppp0

The 65.237.0.254 (obfuscated) is my VPN server.  I don't think it should appear in my route table.  There's no reason for that.  Also, the default route has been changed to ppp0.  I don't want that.  The nm-applet pretends to let me "ignore automatically obtained routes" but that doesn't affect the default route change.  From my /var/log/messages file, I can see the endpoint of the tunnel:

Dec 10 08:13:06 localhost pppd[5046]: local  IP address 10.6.250.118
Dec 10 08:13:06 localhost pppd[5046]: remote IP address 10.6.250.25

I would expect the 10.6.250.25 to appear in the route table, if anything.

Here's what I do manually to get back to normal:

sudo route add -net 10.6.0.0 netmask 255.255.0.0 dev ppp0
sudo route add -net default gw 192.168.0.1
sudo route del -net default dev ppp0

Now I have:

Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
64.238.111.254  192.168.0.1     255.255.255.255 UGH       0 0          0 eth0
192.168.0.0     0.0.0.0         255.255.255.0   U         0 0          0 eth0
10.6.0.0        0.0.0.0         255.255.0.0     U         0 0          0 ppp0
0.0.0.0         192.168.0.1     0.0.0.0         UG        0 0          0 eth0

and all works fine.

The nm-applet doesn't have a way to control my default route and won't let me route my private networks via an interface -- the routes I can add insist on an IP address for the gateway.

Is this a bug?  How can I manually configure my routes in a configuration file?
