NSA 4600 Global VPN Client cannot access Site to Site Network
Hi
We have a site to site vpn connection between Office 1 (10.10.99.0/24) and Office 2 (10.10.90.0/24). We have no problem Remote Desktop from Office 1 to any computers in Office 2.
However, when using Global VPN Connection to connect to Office 1, we cannot be able to remote desktop to any computer in Office 2 at all.
Checking from the log, it shows
TCP handshake violation detected; TCP connection dropped 192.168.168.62, 50844, X1 10.10.90.99, 3389, X1
We follow this guide https://www.sonicwall.com/support/knowledge-base/accessing-remote-site-resources-when-connected-to-the-main-site-via-remote-vpn-client/170505963174776/ but it does not help at all.
Do you have any suggestion that I can use to troubleshoot this issue?

My guess is that Office 2 firewall does not know how to reach GVC IP addresses, in this case 192.168.168.62.
The 192.168.168.0/24 [guess] network needs to be part of the site-site subnets for this to work.

I believe Sonicwall should update their guide https://www.sonicwall.com/support/knowledge-base/accessing-remote-site-resources-when-connected-to-the-main-site-via-remote-vpn-client/170505963174776/ with your solution on top as it will help a lot of people like me.
