SitetoSite VPN <> AWS VPC

[arneboeses]

System: OPNsense 24.7.3_1-amd64
Hoster: Hetzner Cloud
WAN: public IP
LAN: internal network provided by Hetzner

Hi,
Does anyone already successfully set up an site-to-site IPSec vpn between an Opnsense and AWS VPC with the new Strongswan setup? I followed the instructions in the documentation (https://docs.opnsense.org/manual/how-tos/ipsec-s2s-conn-route.html) and the tunnel status gets "up" as well. But I'm not able to route any traffic trough the tunnel. Security groups on AWS are set accordantly and also used by other VPC-VPNs (different firewall OS).

The system has no additional configurations as it was set up only for that purpose newly.

Best,
Arne
