Outbound ISAKMP requests failing

[draccusfly]

Hi,

I hope I am in the right area here, but we are having issues with outbound ISAKMP requests, in particular with Sonicwall client VPN tunnelling.  This has been working in the past, but whenever we try and connect to a client site using Sonicwall VPN the connection just stays there in the connecting status.  Looking at the logs I see "The peer is not responding to phase 1 ISAKMP requests" over and over again but no completion of the request.

I had previously changed to manual outbound NAT to resolve another issue but switched back to automatic and wonder if this has caused an issue?  But far as I am aware once you switch back to automatic the manual rules are ignored, is this correct?

Any one else had any issues with Sonicwall?
