FVS338 IPSec problem

[DaveA66]

Hi

I have an FVS338 in the office and a Draytek Vigor at home, and create an IPsec VPN between themThis has always worked great until recently, the VPN will not establish.
There is not much in the way of logs on the Draytek, but the FVS338 has lots of these in the VPN log:

2009-03-30 09:56:12: ERROR: Ignore information because the message has no hash payload.
2009-03-30 09:56:13: ERROR: Ignore information because the message has no hash payload.
2009-03-30 09:56:15: ERROR: Ignore information because the message has no hash payload.

Yesterday I deleted the config at each end and started from scratch and it worked fine, but now back to the above!

Any ideas?

Thanks

Dave
