I will be able to send you some log output from the Draytek but it doesn't say much. How do I get the debug log file from the client? I only have 2.2.0 under Windows but I have 2.1.7 on Ubuntu, I could connect from both (same machine, dual boot) and send you (but not the list) the logs?

1) the packet to become fragmented since the size is larger due to more

2) the gateway to choke on the proposal because it doesn't like the new 
hash algorithms being included ( although they should just be skipped in 
the case that they aren't recognized ).

Do you have a debug log file, or better yet, an ike packet trace from 
the 2.1.7 and the 2.2.0 negotiation? It would help to see both of them 
to determine if something is amiss. It would also be helpful to see the 
log output from your VPN gateway as it should hold some clue as to why 
the proposal is being rejected when the client is set to auto.

I am testing Shrewsoft Windows Client 2.2.0-rc1 for Windows (connecting
to Draytek 2930).

I have found that despite what the manual says (for 2.1.0) it is
necessary explicitly to set the Phase 2 Transform Algorithm to
'esp-3des' and not to leave it at 'auto' in order to get a connection.

Is this a deliberate change in 2.2.0 or a bug?
