Download files issue when enable Netbalancer

[hminkoong]

Dear Guys

I have a problem and need your help.
I just noticed that whenever i turned on Netbalancer , i faced a download file problem.

---

My Scenario (For example):
My zeroshell has 2 physical interfaces
One interface (ETH00) connect to LAN and another (ETH01) connect to internet .

For Load Balance purpose:

1st
I added ip alias to ETH01 so that ETH01 has 2 ip address i.e.
ETH01:00 = 192.168.7.38/24
ETH01:01 = 192.168.8.38/24

2nd
I connected ETH01 to two Gateways (ADSL Router) via switching hub.
GW1 = 192.168.7.1/24
GW2 = 192.168.8.10/24

Please see image below for network diagram

Then i configured Zeroshell to use Netbalancer (Load balance and failover)
to these two GW.

---

The problem is that whenever i enabled Netbalancer on these two GW ,
i couldn’t successfull download a file . When i started download ,i could
download only few minutes and then dead. However if i used only one
GW, i could download successfull everytime.

* I’m quite sure that the problem caused by the outside servers confused
about the ip address (GW1 or GW2) that connect to them i.e.
When i started download the file , Zeroshell used GW1 connect to the outside
server however after few minutes Zeroshell used GW2 connect to the
server. *

*Are there any solutions to lock state i.e. force Zeroshell to use only one
GW (either GW1 or GW2 ) until download complete *

Thanks in advance

If you set weight to 99 you can minized this problem.

There is already a discussion about this problem in the forum.
A quick resolution would be to apply netbalancing rules according to the source IP. For example if the source is coming from ETH00 and is 192.168.75.0/25 use GW1 otherwise if it is 192.168.75.128/25 use GW2.
