Site To Site VPN Between TZ370 and Trendnet TWG-431BR

I have tried every solution and every suggestion possible to get these 2 devices to talk, and nothing. I need to setup a Site To Site VPN between the 2, can anyone help with this? I can post pictures of the settings if that helps.. but just to clarify, I had a TZ370 instead of the Trendnet, and just replaced it because the TZ370 went bad. So I got the TrendNet to replace the damaged Sonicwall, but I can NOT get it to connect to another location site to site.

    Show us some sanitized tunnel configs and log messages, we may be able to help.

    I actually took MarkD advice & contacted TendNet, Tier 1 & 2 Support couldn’t figure it out, so they’re having Level 3 support contact me later today. I’ll update you here on the outcome

    To expand: Go to the system logs on the Sonicwall and filter by VPN. See what the Sonicwall is saying.

    If it's saying there is no reply, and is constantly retrying, than the TrendNet is not communicating properly. You'll have to investigate if the TrendNet has a direct connection to the internet (e.g. not behind another device) among other things.

    On a side note your current encryption, authentication, and DH Group settings are insecure. When you get the tunnel functional it is highly recommended to change to more secure settings.
