Is it possible to allow any IP to connect to a Amazon RDS instance using MySQL?
Explaining my scenario as requested in the comments:
Amazon RDS by default blocks all the incoming connections which the incoming IP is not listed in the AWS security group "white list". But I use 3G connection on my workstation, so my IP address is always changing. I don't want to update the security group "white list" every time I connect to my 3G with the new IP in order to be able to connect to my RDS instance.
