Does AWS S2S (Site to site vpn - ipsec ) support multiple traffic selectors?
https://docs.aws.amazon.com/vpn/latest/s2svpn/VPNTunnels.html
Look for “Local IPv4 Network CIDR”
But honestly? I leave mine as 0.0.0.0/0 at the AWS end - my datacentre endpoint can choose to select specific CIDR and it works fine
I’m not sure if we are thinking about the same, but AWS S2S VPN has a limitation on the number of active security associations https://aws.amazon.com/premiumsupport/knowledge-center/vpn-connection-instability/
So I guess it wouldn’t work for us… thanks guys
But we do require multiple traffic selectors.
