Site to site VPN problem between Netgear FVG318 and Sonicwall TZ170

Hi, I am having problem to setup site to site VPN between a Netgear FVG318 box and Sonicwall TZ170.
I have followed the manuals of both appliances but failed all the time. I have also searched out a KB article of Sonicwall talking about the trick to setup VPN between Netgear FVS318 and Sonicwall box but that didnt fix my problem.

Any help would be much appreciated.

Please find following the details of my configuration and the error logs on both routers as well.
Please feel free to let me know if you need more information.

Thanks lot for your reply.
Some more background:
The head office is using a static WAN IP which is 60.x.x.147. A ADSL modem is in front of the Sonicwall and it was configured as bridge mode.
The branch B is getting IP dynamicaly via PPPOE on the Netgear router, which is '201.x.x.26" at the moment. A cable modem is in front of the Netgear box. I am not able to access that modem but I think it was also configured as bridge mode because the Netgear is getting WAN IP via PPPOE directly.

To answer your questions:
Sysexpert:
The Sonicwall is pingable but not the Netgear one. I can remotely access Netgear box though.

Dpk wal:
I have done that before I posted the question but it didn't make any difference. So I just left it blank because they are "optional".
What warried me much is the error log on Netgear side: "ERROR: Invalid SA protocol type: 0" which indicates the mismatch of those things you mentioned. I have checked on both sites but could find any mismatch.

I am wondering if it's the dynamic IP problem on the Netgear side even though the IP address on Netgear has not been changed.
A question in my mind is: would it be possible that the VPN can detect the Netgear's IP type is dynamic?

As the IP address was dynamic; there is a possibility that the IP address changed between the time you configured the router and when the VPN tunnel was negotiated; as you have ddns this would mean that whatever the IP address it would always be reachable through the name.
Normally when you configure VPN with dynamic IP; the VPN would come up but would go down when the IP address changes,

Other than this I cannot think of any other reason.

Thank you.

Hi Dpk wal,
The IP address hasn't been changed on the Netgear box since after the configuration done as the modem has been running with no reboot since then.

dpk_wal

I have no logical explanation to offer for this behavior.

Hi Moderator,
Sorry, I didn't mean to choose their posts as solutions though I'd like to assign points to them.
The comment I posted at 14th of October shoud be the right solution for my case.
I wonder if you could help me out with this.
Many thanks.
