Superusers are not staff, but they do have a direct line of communication into the business in order to raise issues, concerns and feedback from the community.
Speak to your IT department and ask them to get you the latest version of the Sonicwall VPN Client, there's an option in the properties tab you can select on the later versions - restrict the size of the first ISAKMP packet sent. With this selected you should be able to connect. I had the same issue and it worked for me.
I have v 4.9.9.1016 and there are no options for what you are suggesting (send me a screenshot if you can) - attached are the only options I have on mine.
PlusNet made changes to their routing to allow traffic to route back to me so the problem is fixed but would be interested in your option,
I don't have that setting on my SonicWALL.. odd.. anyhow I will investigate that... might be a switch somewhere.. I am sure answer is on Google somewhere...
But ultimately I sent a private message to bobpullen (he is on same thread as above). He will need first three sections (octets) of your external IP address (I presume you know but put "whatsmyip" into Google). He did it within a day so a quick turnaround.
