[Openswan Users] Main Mode recieved not authorized

[Michael Dobeson]

Morning peoples.

I'm setting up a IPSEC/L2TP VPN server for a private wireless network. 
However I've hit a snag. No initial ipsec connection.
I'm told I should see a line "responding to Main Mode" in the 'secure' log. 
This should be there regardless of the L2TP connection at this stage.
However the log is full of the following:

>Nov 11 13:15:06 Mcrae pluto[9985]: packet from 192.168.1.3:500: initial 
>Main Mode message received on 192.168.1.253:500 but no connection has been 
>authorized
>Nov 11 13:15:08 Mcrae pluto[9985]: packet from 192.168.1.3:500: ignoring 
>Vendor ID payload [MS NT5 ISAKMPOAKLEY 00000003]


I've tried several different ipsec.conf setups both PSK and Certificate 
based but always recieve this error.
I'm guessing I've missed something simple and obvious cos I've tried many 
different setups and they all produce this result.

The WINXP test box (192.168.1.3) is on the same subnet as the public 
interface on the Linux box (192.168.1.253).



Any assistance would be greatly appreciated
Michael
