Net Balancer…

[maxchock]

Hi all,

I’m very new to Zeroshell, and I have little knowledge about networking. I’m trying to setup a load balancer which can do traffic shaping for my Internet Cafe. Before deploy to a real PC I actually have it install in a VirtualBox.

here is the setup of my environment.

here is the screenshot of the zeroshell-> setup->network

here is the screenshot of “NetBalancer”

i can online using DEFAULT GATEWAY or Streamyx but when I enable Load balancing, the Zeroshell itself fail to run the Ping test under “Utilities”-> IP Check

As it’s return the DNS Lookup ERROR, I did actually add a line into “DNS Forwarder”

The Zeroshell still fail on the Ping test if keyin domain name such as google.com but it return success if I key in google’s IP instead of URL.

So I wish someone can help to solve my problem. Thanks for helping in advance.

First post here the contents of the “DNS Options” window that pops up. I suspect it is a query – recursion issue.

[maxchock]

is this the one you meant?

[ppalias]

Yes… add the following

recursion yes;

allow-query {10.0.0.0/8;127.0.0.0/8;};

change 10.0.0.0/8 with your LAN address space.

I tried using

“recursion yes;
allow-query {192.168.1.0/8;127.0.0.0/8;};”

and

“recursion yes;
allow-query {10.1.1.0/8;127.0.0.0/8;};”

neither of them are working, it gave same error.

Do me a favor and open a shell to execute these commands.

 cat /etc/resolv.conf

dig www.yahoo.com

netstat -anp | grep :53

[maxchock]

ok,

“cat /etc/resolv.conf” return
nameserver 127.0.0.1

dig http://www.yahoo.com return
; <> DiG 9.5.1-P2 <> http://www.yahoo.com
;; global options: printcmd
;; connection timed out; no servers could be reached

netstat -anp | grep :53

I tried to vi the resolv.conf, but permission is denied even i “su”…

[ppalias]

named is up, but no servers can be reached. I suspect a firewall blocking your box from reaching the forwarders.
Is

ping 208.67.220.220

answering?
What is the output of

iptables -L -v

?

[maxchock]

ping is working and replied.

below is the screen shot of iptable.

[ppalias]

As I said there is a firewall blocking you.

0 0 ACCEPT     udp  --  any    any     anywhere             anywhere            udp spt:domain state ESTABLISHED

Means you don’t receive DNS replies back. You have not printed SYS_OUTPUT chain, which will show you that your system sends DNS packets out.

[maxchock]

hmm…

I don’t understand, because i don’t have any firewall setup in my network. And why the DNS can reply back if i’m using only 1 WAN?

Thanks for helping me. Really wish to deploy zeroshell in my cafe.

[ppalias]

Have you added the

recursion yes;

allow-query {192.168.0.0/16;10.0.0.0/8;127.0.0.0/8;};

to the options window? If not what is the error?

[maxchock]

add to where?? which part?

Thanks.

[ppalias]

In the DNS-> Options tab.
