Just installed two RV120W (latest firmware 1.0.4.10) and configured a site-to-site VPN tunnel that works fine. Every day, my client calls me up saying that the VPN link doesn't work, and I need to reboot both routers so they can connect again. Once it's up and running, no problems for the whole day.
Setup : 1 router on static IP, 1 router behind other router (from ISP, dynamic IP) with ports UDP 500 and 4500 opened.
In log of router with static IP, I can see this message :

Any ideas ?
