WR44 L2TP OVER IPSEC CLIENT WITH WINDOWS SERVER 2008 R2

0 votes
I'm having trouble configuring your WR44 as an L2TP over IPSEC client of the Windows Server 2008 R2.
RRAS is configured using a preshared key , and all parameters are default.
In the eventlog of WR44 , when I run the ping command I only see the command:
IP Act_Rq to PPP 5-0: s_ip[0.0.0.0] d_ip[192.168.10.12].

The WR44 configuration has been done following the Application Note 26.

Hi

That looks like the WR44 is trying to open a connection but does not have a source address set

there should be information in the server if there are provblems and it would also need to see the debug.txt from the router to see the configuration

Hi

I have not tried this to connect to a 2008R2 server from the eventlog it looks like it is either filing IKE due to wrong or unsupport encryption

or   

it is not passing the firewall on the 2008 server

the encrtption i found on technet


L2TP/IPsec
IKE Main Mode will support:
·         Advanced Encryption Standard (AES) 256 (new), AES 192 (new), AES 128 (new), and 3DES encryption algorithms.
·         Secure Hash Algorithm 1 (SHA1) integrity check algorithm.
·         Diffie-Hellman (DH) groups 19 (new) and 20 (new) for Main Mode negotiation.
IKE Quick Mode will support:
·         AES 256 (new), AES 192 (new), AES 128 (new), and 3DES encryption algorithms.
·         SHA1 integrity check algorithm.

which would suject wrong encryption

and this about firewall

Ok, where to begin.....
After having getting what you are trying to do working (it took 3 weeks) I know understand why Cisco does not feel the least bit threatened by Microsoft.

First:
You cannot use VPN dial in to make this work. It doesn't work, none ot the tick boxes and presse buttons work (like use static IP, etc...) forget it. It doesn't work.

What does work is Site-to-site vpn. Set RRAS up for that and have the digi call in, works a treat, will route traffic properly, everything.

Cheers,
John
