In the settings I was trying to find out if you had specified a Remote VPN Gateway. If you have you have to put your PSK in the IKE Pre-Shared Key here. If not, you have to put it in VPN IKE / IPSec General Setup. If you used the VPN IKE / IPSec General Setup method, have you un-checked Medium as the security method (and preferably DES as well as it is crackable)
What makes you think the Astaro is unhappy with the response? Do you have a log from it?

The log from the Astaro says:
No acceptable response to our first Quick Mode message: perhaps peer likes no proposal
Currently I've not specified a remote gateway and have it configured as you suggest. But I have tried it the other way too with no joy.
I'm starting to think a "dial-out" only method is the way to go here

It looks like the phase 1 (main mode) negotiation is working and the phase 2 (quick mode) is failing. Are you sure the option on the Astaro matches what the Draytek is expecting? Can you try changing it to something else with a key length of 128 or 256 (but could be talking rubbish here). I'll have to check when I get home to see which 3DES algorithms are being used with my Drayteks to my Linux box.

you'll have to excuse my ignorance but does it use the same phase 1 and 2 settings when make and receiving requests? if so why can I make the connection one way and not the other?
As for the key length I am using 256
Thanks

I may have been a bit wide of the mark here. When my Drayteks dial my Linux box, my main mode connection reads:
and my 2900 phase 2 connection reads:
whereas my 2600 phase 2 connection reads:
I don't know if this gives you any clues. Both routers start with 3DES but I allow the 2900 to use AES for phase 2.
Otherwise you'll have to play around. I'm not sure I can help much more.
Code:
auth=OAKLEY_PRESHARED_KEY cipher=oakley_3des_cbc_192 prf=oakley_md5 group=modp1024
and my 2900 phase 2 connection reads:
Code:
ESP=>0x6fdec8e3 <0xf392d0cc xfrm=AES_0-HMAC_SHA1 NATOA=none NATD=none DPD=none
whereas my 2600 phase 2 connection reads:
Code:
ESP=>0x7cf9f624 <0x79d7e407 xfrm=3DES_0-HMAC_SHA1 NATOA=none NATD=none DPD=none
I don't know if this gives you any clues. Both routers start with 3DES but I allow the 2900 to use AES for phase 2.

Thanks for all your help, You've been a star.
At the moment I've got them working in dialout mode and I'm waiting on the guys from Astaro to come back to me. If I get an answer I'll post it.
Thanks again!
Rob
