Can you connect to Amazon ElastiСache Redis outside of Amazon?

Question

I\'m able to connect to an ElastiCache Redis instance in a VPC from EC2 instances. But I would like to know if there is a way to connect to

Answer 1

Its is not possible to directly access the classic-cluster from a VPC instance. The workaround would be configuring NAT on the classic instance.

NAT need to have a simple tcp proxy

YourIP=1.2.3.4
YourPort=80
TargetIP=2.3.4.5
TargetPort=22

iptables -t nat -A PREROUTING --dst $YourIP -p tcp --dport $YourPort -j DNAT \
--to-destination $TargetIP:$TargetPort
iptables -t nat -A POSTROUTING -p tcp --dst $TargetIP --dport $TargetPort -j SNAT \
--to-source $YourIP
iptables -t nat -A OUTPUT --dst $YourIP -p tcp --dport $YourPort -j DNAT \
--to-destination $TargetIP:$TargetPort
