Wanted VPN tunnel between elastic ip and on prem static IP?

Question

I'm new to AWS, and I have one Elastic IP on my account that I'd like to use to establish a VPN connection between my on-premises and AWS accounts.
I tried setting up an OPNsense firewall instance and connecting my elastic IP to form a tunnel, but it didn't work?
I also tried connecting Elastic IP to a network interface, but it didn't work.

I also changed the security groups to allow everything, including all tcp/udp/icmp traffic.
I also added routes  tables as required.But packet from on prem is ever showed up at aws end.

Is there anything I'm missing?

Answer

Are you using AWS VPN or 3rd party VPN ?

If you are using a 3rd party VPN, please check if you are allowing the ESP/UDP traffic on the specific ports required.

Also, the routing needs to be verified internally and check if you are able to ping the IP from On-premise IP.
