Gio999

Hello

I have read this https://support.zyxel.eu/hc/it/articles/360001378833-Configurazione-da-client-VPN-a-sito-su-dispositivi-USG-ZyWall

And make as it tell but i see this error in log connection

 Default (SA Ikev1Gateway-Ikev1Tunnel-P2) is opening.

Default (SA Ikev1Gateway-P1) SEND phase 1 Main Mode  [SA] [VID] [VID] [VID] [VID] [VID] [VID]

 Default (SA <unknown>) RECV Informational  [NOTIFY] with NO_PROPOSAL_CHOSEN error

Something wrong on one of the sides of the VPN... "NO_PROPOSAL_CHOSEN" means that into phase 1 there's no match between allowed cyphers on the firewall and allowed cyphers on the client.
Phase 1 -> check the gateway section into firewall than the phase 1 into the client.

Be sure to have Policy Control rule like from IPSec_VPN to ZyWALL as that one catches me out.

Building the correct routes and firewall rules for the segment of IPSec

The user manual and a skilled-enough network competency on topology design.

Which was the issue of the creation of the VPN? Please, mark the correct post/solution, or feel free to explain what was wrong.
Maybe could help the next person like you that's having the same problem
