The list of IP addresses that can be used to allow a connector to access an AWS Data source are as follows:
1. prod-e2-ps1.paxata.com: 18.104.22.168
2. prod-e3-ps1.paxata.com: 22.214.171.124
3. prod-e2-auto1.paxata.com: 126.96.36.199
4. prod-e3-auto1.paxata.com: 188.8.131.52
Note: customers might want to open their firewalls to allow connections (whitelist) from these IPs to connect to DBs, etc.
I hope this helps!
