> 1. Create a network say N1 with Network offering "Conserve Mode Enabled and
> all other services with Virtual Router"
> 2. Create an instance with N1
> 3. After successful creation of instance, Navigate to Network and add port
> forwarding rules .
> 4.After successful addition of port forwarding rules .Login to the router and
> type iptables -t nat -L we will find the port forwarding rules
> root@r-22-VM:~# iptables -t nat -L
> Chain PREROUTING (policy ACCEPT)
> target prot opt source destination
> DNAT tcp -- anywhere 10.147.30.184 tcp dpt:ssh

> Chain POSTROUTING (policy ACCEPT)

> SNAT all -- anywhere anywhere to:10.147.30.184
> SNAT tcp -- 10.1.1.0/24 conserve tcp dpt:ssh
> to:10.1.1.1
> 5. Reboot the router from outside of the management server
> 6.Again type iptables -t nat -L and check whether the rules are persistent .
> Observation :
> Post reboot from outside of cloudstack , PF rules are not present on the
> iptables of VR.
> In database the pf rules are present
> mysql> select * from port_forwarding_rules\G;

> dest_ip_address: 10.1.1.114
> dest_port_start: 22
> dest_port_end: 22
> 1 row in set (0.00 sec)
> *****************************
> In forwarding rules.json the rules are present

> But in iptables the rules are not present

> Chain OUTPUT (policy ACCEPT)
> target prot opt source destination
> Chain POSTROUTING (policy ACCEPT)

> In the above one we cannot ssh to the virtual machine
> ssh [email protected]
> ssh: connect to host 10.147.30.184 port 22: Connection refused
> Note : When the vr is rebooted from cloudstack , all the rules are again
> fetched.
