AWS Site to Site VPN 0 BGP Routes shown

The VPN Tunnel has already been setup and shows connected on both sides as show in the pics. The AWS side just shows 0 BGP Routes and I am unable to reach any resources between the 2.

Hi David Woerz

Ping was working with Static Route earlier? I would suggest you test it with a static route before testing with Dynamic routing : 

https://docs.sophos.com/nsg/sophos-firewall/18.5/Help/en-us/webhelp/onlinehelp/AdministratorHelp/VPN/SiteToSiteVPN/VPNCreateRouteBasedVPN/index.html#add-a-route-ho 

As suspecting issue with BGP configuration you may refer to the below link to check BGP configuration and output as desired:

Thanks and Regards

Turns out the guides have the you set the route as static when configuring the VPN on the AWS side. I recreated the AWS Site to Site VPN and chose dynamic and everything started working (after going and making the changes to the config on the Sophos side since I created a new VPN)

Could you confirm which guides you used so we can modify as needed?

The following indicates selecting dynamic on AWS: https://community.sophos.com/sophos-xg-firewall/f/recommended-reads/125806/sophos-xg-firewall-set-up-ipsec-tunnel-between-aws-vpn-gateway-and-xg-v18-with-bgp 

Here is one I was following.

Thank you for sharing. For your purpose, the relevant doc guide would be: Set up IPSec tunnel between AWS VPN Gateway and XG v18 with BGP
