No internet access to vms behind router, but the router has access
Hello everyone
I have few vms setup in "Advanced zone" a mix of Windows + Linux vm, they
all able to ping default gw 192.168.1.1 however none of them able to access
the internet.
I logged in to the router, and I'm able to ping my virtual machines, and
I'm able to ping outside (4.2.2.2 and 8.8.8.8 ).
[image: Inline image 1]
I did the following
1. reboot the router and later destroy it and it gets recreated again.
2. Create new network ( which launched new router with different public IP
from the pool) (same issue)
3. login to the router and issue iptables -F
I'm not sure what else to try.
Your help is highly appreciated.

You would have applied a VLAN to Public traffic when setting up the Zone, has this VLAN been setup properly on your switches and Final Internet Router.

Hi,
Did you try by adding egress firewall rules for outgoing traffic on the network ?

After upgrading from 4.0.2 to 4.1 I noticed that all of my vms lost access to the internet.
I'm able to ping my gateway, but unable to ping any external address.
After checking few things, I found that outgoing traffic is getting blocked.
I had to added ingress rule to my network 0.0.0.0/0 Protocol: All to allow outgoing traffic.
And that resolved my issue.

Re: No internet access to vms behind router, but the router has access
Posted by Indra Pramana <in...@sg.or.id>.
Hi Dean,
By default, the virtual router is also performing firewall function and
will block all incoming and outgoing traffic. To allow the VM to gain
access to the public network and the Internet, go to Cloudstack GUI >
Network > Guest networks > (your network name) > Egress rules. Add this
rule to allow all outgoing traffic:
Source CIDR: 0.0.0.0/0
Protocol: All
Hope this helps.
Thank you.
