S2S routing issues

Hey Fellas,

​

I am hoping you guys can help point me in the right direction here. Sorry for the noobish question, still learning here. I currently have two site to site tunnels. One between our Nevada office and Boston Office, and one between our Nevada Office and Polish office.

​

I am running into an issue where I can't get our remote offices to access any of our AWS resources. In our Nevada office I currently have 2 tunnels to AWS. Locally we can reach all of our AWS resources but when I remote into a system in either Boston or Poland I can't reach any of the AWS servers. I included the AWS network in the site to site configs for both locations. I have a route in place on my local sonicwall that states any traffic locally or from Boston or Poland that goes to AWS to go out the AWS tunnels.

​

Am I missing something here? Do I have to create direct site to sites to AWS from each location instead of routing the traffic through our Nevada location? Any help would be greatly appreciated.

​

Thank you!
