Even when all rules are empty in cloudstack ( Egress rules and firewall ) the
eth3 device will be created

0 0 SNAT all -- * eth3 0.0.0.0/0 0.0.0.0/0
to:185.22.***.***
In order to make internet working on instance i need to :
1) add egress rule for guest network ( 172.17.150.0/24 all protocols )
2) delete wrong SNAT rule > iptables -t nat -D POSTROUTING -j SNAT -o eth3
--to-source=185.22.***.***
3) add right rule > iptables -t nat -A POSTROUTING -j SNAT -o
eth2 --to-source=185.22.***.***
4) bring eth3 down.
P.S. since its a test CS environment I can give you a full root access both to
management and host

> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Management Server
> Affects Versions: 4.3.0
> Environment: Build from 4.3 using 64 bit system templates.
> Reporter: Sangeetha Hariharan

> KVM - Advanced zone Isolated networks - Egress rules are not functional.
> Steps to reproduce the problem:
> Advanced zone with 2 KVM hosts (rhel6.3), Isolated network with 20 vms.
> Create a egress rule to allow all traffic to all cidrs.
> From Vm , try to ping google.com
> We are not able to ping/ssh outside from the VM.
> Egress rules are programmed in the router.
> But I see that the router has as many NICs as the number of Vms that it
> services asssigned to the same public Ip address but with 2 different MAC
> address.
