I attached a Second ENI to my Ubuntu OS machine on AWS VPC, the internal IP of this new ENI is 192.168.12.24. When I try to SSH in to this machine from another machine in the same VPC I get a connection time out. I am able to SSH in to the first ENI of the same machine both from inside and from outside the VPC.
Route command shows the following
Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.0.0 * 255.255.240.0 U 0 0 0 eth0 192.168.0.0 * 255.255.240.0 U 0 0 0 eth1 default 192.168.0.1 0.0.0.0 UG 100 0 0 eth0
I am new to iptables and iprules, any help would be really appreciated.
