CLOUDSTACK-8688 - default policies for INPUT and FORWARD should be seâ¦
â¦t to DROP instead of ACCEPT
- In order to be able to access the routers via the link local interface,
we have to add a rules with NEW and ESTABLISHED state
Tests:
* Deployed 2 zones, basic and advanced, using KVM as hypervisor
* On the basic zone, created 1 security group, added ingress rules to open
port 22 and deployed 1 VM
* SSH into the router and checked that the INPUT/FORWARD policies were
set to DROP
* SSH to the VM
* On the advanced zone, created 1 single VPC (with 2 tiers, 2 puc IPs, 2
VMs and 1 ACL), 1 redundant VPC ((with 2 tiers, 2 puc IPs, 2 VMs and 1 ACL)), 1
isolated network (with 1 VM and 1 pub IP), 1 redundant network (with 1 VM and 1
pub IP)
* SSH into all routers to check that the INPUT/FORWARD policies were set
to DROP
* SSH into all VMs to test the communication
