Multiple Proposals l2tp IPSEC

Hi guys,
This is my first post in the forum, because other post or google did not help and I’m going a bit crazy here; I hope my issue con be resolved. I set up a l2tp server using the following tutorial for my windows clients:

My iphone connects great, but the issue that I’m having is that i cannot connect my IP phones to it because they are not the greatest, and they do not support 3des encryption. My solution was to set up null encryption in proposals and I managed to get them up and running. My issue is that by adding null, the phones don’t work, I had to remove 3des. When I remove 3des, the windows clients and iphones do not work.

What are the steps if possible to set up multiple proposals, I have tried to change the proposal checks in peers…obey, strict, etc… I have also tried to change around many configurations in IPsec, but I either get the phones or clients working..not both

Im I going the right way with this? There is no way to set up multiple L2tp servers with different policies… :S

Thanks in advance for the support :stuck_out_tongue:
