Gateway: web address of my company
Username: just my username without any domain info
Password: regular login password
Domain: empty

Advanced: both MSCHAP only, MPPE, BSD, deflate,and tcp header all checked.
IPV4 automatic

so only chap – mschap – mschapv2 is enabled

I followed all the tips, and when I got to this one, it started to work.

so only chap – mschap – mschapv2 is enabled

I think the key line here is:

“LCP terminated by peer”, which means that the server you connected to explicitly closed the connection (LCP = Link Control Protocol).

Maybe you need to adjust a few more settings, perhaps this post helps: http://ubuntuforums.org/showthread.php?t=1095546

Ahh, the “wonderful” VPN issues (in every release… I really hope this stablizes…)
However, your solution might be really simple:

Try manually restarting the network manager service like so:

sudo /etc/init.d/network-manager restart

This helped in my case. However, the relevant error message seems to be:

Dec 4 19:15:22 Adarak-Prime NetworkManager: nm-vpn-connection.c.828: NeedSecrets failed: dbus-glib-error-quark Rejected send message, 1 matched rules; type=”method_call”, sender=”:1.2″ (uid=0 pid=614 comm=”NetworkManager)

i.e. the nework manager fails to retrieve your (saved?) password.

Hope this helps,
Olaf
