Can't establish IPsec VPN site-to-site connection
I'm currently building a VPN site-to-site. I have a USG110 to the site A, and a USG100 to the site B. I can't make a connection between these two sites with IPsec VPN. I'm also trying building the VPN site-to-site with my USG110 from the site A and my ISP professional box (which support VPN site-to-site) and I can't also establish a VPN connection.
I have checked all parameters from IKE phase 1 and phase 2 and they are both the same. I don't understand what is wrong.
From the log of my USG110 from the site A, I have this :
Can anyone help me to establish this IPsec VPN site-to-site?
Thanks in advance!
