RV042 load balancing problem

We have two network connections coming into the office. One is a private WAN and the other is an internet WAN. We have a RV042 Router configured for load balancing. On Wan1 we have our private WAN which includes Exchange, and 6 VPNs. On WAN2 we have a Public IP, and workers from home. Both connections are 5Mg T1s and both have the ability to reach the internet but only wan2 has a public IP (76.x.x.x) were as WAN1 has a private IP. (10.x.x.x).
Now were the problem lies is our new web based Payroll system does not support load balancing. We have to shutdown one side when we want to do payroll (turn load balancing off.)
Now is there a way to make our payroll computers only use one side? modify host file maybe? Or force a certain MAC address to only use WAN1 OR is there a better router that can Accomplish this?
Any help would be appreciated

I ran in to this problem at a client where we had an RV042. Different scenario though. We had 2 static IP from 2 different ISP's. We had an accounting program that used HTTPS on port 443 hosted at a different location. We had to bind outgoing port 443 to WAN1 to prevent disconnect problems. This caused a problem in case that internet connection went down.
What we did was create a service on the RV042 for TCP port 4433 and binded the traffic to WAN2. On the side hosting the accounting package we created a rule in that router to translate all public port 4433 requests to internal 443 requests.
On the workstations we had to leave 2 desktop shortcuts one that pointed to 443 and one to 4433. That way if one link doesn't work they can just use the second link.
It's not the best solution but at least it works until they ok a swap out to a router that supports better binding.
I'm not provided this as a solution but maybe it can spark an idea of a workaround.
I know a company called Xincom use to make a dual wan router that was decently priced that supported strict binding per internal ip address. The build quality wasn't the best and they use to die all the time but maybe their new units are better. When they worked though they were very good and I never had a problem.

RV042 Load Balancing not working correctly?

We have an RV042 on firmware version 1.3.13.02 and 2 ISPs:
WAN1 = Telepacific T1
1.5Mbps down and 1.5Mbps up
WAN2 = AT&T U-Verse
12Mbps down and 5Mbps up
I have it set to Load Balance, Primary WAN = WAN2
Network Service Detection enabled, only pinging the Remote Host of 4.2.2.2 and set to Generate Log
Bandwidth is set to:
WAN1 = 1000Kbps upstream & downstream
WAN2 = 5040Kbps upstream & 12000Kbps downstream
It seems to pick WAN1 a lot of the time. Do I have something setup wrong?

Ok, so what do you recommend? To setup binding for ports important to direct over say… WAN1 (my fast access) shall I also keep the bandwidth management set up as is, example:
For me it’s confusing because this config appears to be clear to me that has to control traffic the way I want .
Thanks for your response.

Bind Load balancing problem..expert help required

Hi there.
My RV042 has 2 WAN connections. One is connected to a Public Internet (WAN1) and the DMZ/Internet to my VPN router (WAN2)
Behind the VPN router connected t my WAN2 is the finance servers at network 10.36.88.0
Both users local and those who connects using PPTP VPN clients can access resources in the LAN
My problem is that due the round robin of load balancing sometimes they cannot reach the finance server
I tried playing bind the HTTP port and creating some rules with no luck
We want our users to use the WAN1 for all the web pages except those behind the VPN
Is there a way i can make that if my users access my finance server they go trough the WAN2?
Could you please provide me some guidance? (Rules, binds. etc)
in thi case woul be
An access rule or bind that all the WEB traffic for 10.36.88.0 flows to WAN2.

If you type "show real" you will probably see the column for "Data In" rising. This column is all the way on the right side of the display. This indicates that the server has received requests that it has not responded to.
By default, the LD does not use the Data value to fail a server. So by default, the data threshold for all the real servers is "0". If you set it to a non-zero number, the LD will start to use it.

RV042 load balancing and OWA

I have a rv042 router with two internet connections. I have setp the WAN1 and WAN2 and set the load balance mode.
Surfing on internet is then not a problem and I checked that I was using the two internet connection.
However if I try to connect to my corporate (OWA) outlook web access i am looping on the first page where I should provide my credentials.
I know that most of the load balancer could be set up with a sticky bit to keep the session on the same WAN connection, but reading the documentation, googling and searching on this community I do not find any help.
Does someone have an idea and could help me.
Thanks in advance.

Hello,
i've have a RV042 too, and i have the same problem.
Loadbalance work for every single request, so every website get requests from both connection even if there is a single user browsing.
Website side, some requests are "logged in" (if request came from the same IP the user logged in), but not if request come from the other wan (because IP mismatch). I've experienced many problems with many websites, not only OWA, not only requesting me to log-in continously, but also server-side crash because server session get lost in the middle of transactions.
Protocol Binding is NOT the solution, since it will require to bind all HTTP to just one connection (this way, where is loadbalance?) and if that wan fails over you get lost of connectivity.
Right now I didn't found any solution to use loadbalancing correctly, the right way to do would be that the RV042 remember the association CLIENT/SERVER->WAN, so that once i client connect to a server the router whould use only that one WAN, and when a WAN fails the table get cleared to restart balancing requests on remaining WANs.
Hope to see this function on next firmware..

RV042 Load balancing function

I have Rv042 so I need it to make load balancing for 2 ADSL lines.
The 2 ADSL modems working as a router (not bridge) so I connect ADSL1 (adsl router) to Internet1 in RV042 and ADSL2 to internet2/DMZ .
In the RV042 configuration I make WAN1 and WAN to obtain the ip automatically from the DHCP which are enabled in the ADSL routers.
Also in RV042 the DHCP is enable to assign ip address to the LAN.
from a PC try to access the internet I can't.
I did the same scenario with QNO FQR8010 it's working but with RV042 it's not.
What is the problem.
Note: I need the ADSL routers to still work as routers.

RV042, Load Balance issue

Hello,
I'm a newbie to routers and on this discussion.
I've purchased a Linksys RV042 hoping I could connect my two ISP.
Both of them are 1/1 Mb, first is DSL second PPPoE connection.
The problem is that on system summary page it doesn't show me that second WAN is connected. Even when I trying to manually connect to Internet it doesn't help.
When this connection is in Load balance Mode, internet is very slow, sometimes it's even disconnected.
My question is:
How to configure Load Balance properly?
I've tried this page:
http://www.cisco.com/en/US/products/ps9923/products_qanda_item09186a0080a36632.shtml
but it didn't helped.
Or maybe it's just a demo of this option and doesn't work at all?
Thanks for the reply.....

Eliviszopa,
Hi. My name is Tiya and I am one of the Cisco SMB Support Engineers. I have been eyeing your post and I would like to add a few recommendations.
From what I've gathered, you are having an initial problem with your Dual-WAN configuration, in that you are unable to have both WAN interfaces Live at the same time. I will list a few things that will help you in determining if there is an issue with your RV042's Dual-WAN configuration and connectivity.
I understand your Network Topology to be: [ISP Modem 1 & ISP Modem 2]---->RV042---->LAN Clients (PC).
First thing, we need to ensure your router it at the most current firmware version for optimal performance. The RV042 series routers are currently in their 3rd HW revision, so we also need to ensure we download the firmware that is compatible with the HW version of your RV042
To locate HW version:
Look on the bottom of your RV042.
You will find the Serial Number and MAC      address sticker.
The HW Version will be visible by the      Model Number on that sticker.
Image below has a Red Square around the      Model Number and HW version of an older RV042 as a reference. HW is indicated      with 'v' and rational number, i.e. v1.1, v2.0. Your sticker may look      slightly different, but the content will be the same:
Now that we are certain of the HW version, check the release notes below to check the best firmware version for your RV042. I have provided a link below to the RV042 Release Notes:
Firmware v 4.0.0.7 Release Notes:      http://www.cisco.com/en/US/docs/routers/csbr/rv0xx/release/rv0xx_rn_v4-0-0-7.pdf
Firmware v 1.3312.19-tm Release Notes:      http://www.cisco.com/en/US/docs/routers/csbr/rv042/release/notes/RV042_RN_v1-3-12-19-tm.pdf
If your RV042 is using neither of the 2 firmwares, follow this link to download the correct version for your router:
http://www.cisco.com/cisco/software/type.html?mdfid=282414010&flowid=784
I would recommend you download and      'flash' your RV042 with the current compatible version of firmware to      address the possibility of software corruption.
Now, we need to reset your RV042 to factory defaults to remove any parameters previously configured and also, in essence, clear the router's memory so that we can start afresh. When this happens, your RV042 will return all settings to their default state; in other words, it will be as if you are pulling it out of the box for a new install. To do this:
Disconnect the RV042 from your network,      so that the only item the RV042 is only connected to the power outlet.
Locate the reset button on your RV042.      This will be on the front of your router and it will be recessed a bit.
Use a small tipped item; paperclips      usually work best, to hold down the reset button for 30 secs. Anytime less      will not guarantee a full reset to factory defaults.
Connect your RV042 to your PC. After      about 30 secs, ensure that you have an IP address of 192.168.1.100 on your      PC.
Now, let's test each WAN port with each of your ISP connections.
The next few steps will take us through a process that will ensure both WAN ports are working, and ultimately will help is in determining your Dual-WAN connectivity performance.
Connect one of your DSL modems to WAN1 and configure the WAN1 interface accordingly:
· DSL connections typically are UN-bridged by default; where you will see the modem is performing NAT. You will use DHCP as the WAN tupe for UN-bridged DSL connection types. This UN-bridged state can be recognized quickly in a couple of ways.
o    There is a PRIVATE IP address displayed as the WAN1 IP address, e.g. 192.168.x.x. where X is a number 0-254, 10.x.x.x where X is a number 0-254, or less commonly, 172.16.x.x where X is a number 0-254.
o    When connecting to the modem directly to your PC, you are able to reach the Internet.
o    If your DSL connection is UN-bridged, you must make sure the LAN IP Subnet of your Modem and Router are NOT the same.
o    Again, you will use DHCP as the WAN type for UN-bridged DSL connection types.
· DSL connection that is Bridged will require a PPPoE Username AND Password. This PPPoE username and password will be entered on the RV042 under the WAN type PPPoE. PPPoE connections can be quickly recognized in the same manner:
o    There is a PUBLIC IP address displayed as the WAN1 IP address AFTER correctly configuring WAN interface to use PPPoE and using correct UN/PW.
o    You are NOT able to reach the Internet when connecting your PC directly to your RV042.
· Contact your ISP to assist you in determining the bridged state of your modem to be absolutely certain.
2.     After you have properly configured WAN1 and confirmed Internet connection, configure WAN2 in the same fashion.
3.     Change Primary WAN to WAN2 by going to the following location in the RV042:
· System Management>Dual-WAN> Smart-Link Backup Primary : WAN2 (change this option)
4.     Disconnect DSL Modem from WAN1 and connect to WAN2.
5.     Power cycle the DSL Modem, RV042, and also disconnect your PC from the router as well while it is powered down.
6.     After about 5-10 sec, and in this order, power on your Modem, power on you RV042, and reconnect your PC to one of the LAN ports of your RV042
7.     After about 30-60 secs, test for Internet connectivity.
Now we will do the same for your other ISP connection.
1.     Disconnect all devices from the RV042, save your PC.
2.     Change Primary WAN to WAN1 by going to the following location in the RV042:
· System Management>Dual-WAN> Smart-Link Backup Primary : WAN1 (change this option)
3.     Connect 2nd ISP connection to WAN1 and configure according to Modem configuration, either DHCP or PPPoE.
4.     Power cycle the DSL Modem, RV042, and also disconnect your PC from the router as well while it is powered down.
5.     After about 5-10 sec, and in this order, power on your Modem, power on you RV042, and reconnect your PC to one of the LAN ports of your RV042
6.     After about 30-60 secs, test for Internet connectivity.
7.     Do the same for WAN2 using your 2nd ISP connection
At this point, we should now know for certain if both WAN Interfaces will allow Internet connectivity.
If you have problems with these steps, repost with the steps you took and the results.
If things are OK, then we will continue with configuring the router for Load Balance Mode:
1.     Navigate to System Management>Dual-WAN and change your selection from Smart-Link Backup to Load balance
2.     Configure both WAN1 and WAN2 with the configuration that correlates to the Modem connection it will receive.
3.     Connect both Modems to the correct WAN port on the RV042.
4.     Power cycle all devices; Both Modems, RV042, and PC
5.     Navigate to RV042 management page and check to see if there are IP addresses for WAN1 & WAN2 Interfaces.
If you have problems with these steps, repost with the steps you took and the results. Let us know your results.

RV042 Load Balance with VPNs

I want to split my traffic between two ISP's. I want all traffic to pass over one connection EXCEPT my VPN tunnels, which I want to use the second ISP. How should I set up (protocol binding?) to accomplish this? (I have run into various problems trying to load balance all traffic. So I am trying to "partition" traffic.)

Which firmware is running on your RV042?
What are the WAN connection types of the RV042, e.g. DHCP, PPPoE or static IP?

Wgate Load Balancing Problem

Hi Folks,
We have ITS 6.20 Patch level 33 installed which connects to our R/3 system. We are trying to add multiple Agate servers (not multiple Agate processes) to one Wgate. We installed agates on two hosts, host1 and host2. We then installed wgate on host1 which we connected during the time of installation to agate on host2. It connected fine and we were able to get the webgui and also able to login to R/3 system. At that time we had problem in going to native ADM instance as we were getting http 500 error (we had re-installed ADM instance on both the hosts after the whole exercise of installating agate and wgate). Hoping that we can solve native ADM problem later, we added the the second agate which is on hosts1(the same host on which wgate is) by adding the entry for agate 2 in the wgate registry xml file.
<key name="Agates">
      <key name="Agate1">
       <value name="Host" type="text">host2</value>
       <value name="PortAGate" type="text">sapavw00_******</value>
       <value name="PortMManager" type="text">sapavwmm_******</value>
       <value name="Type" type="text">1</value>
       <value name="SncNameAGate" type="text"/>
       <value name="SncNameWGate" type="text"/>
       <value name="MultiProcess" type="text">no</value>
       <value name="Available" type="text">yes</value>
      </key>
      <key name="Agate2">
       <value name="Host" type="text">host1</value>
       <value name="PortAGate" type="text">sapavw00_******</value>
       <value name="PortMManager" type="text">sapavwmm_******</value>
       <value name="Type" type="text">1</value>
       <value name="SncNameAGate" type="text"/>
       <value name="SncNameWGate" type="text"/>
       <value name="MultiProcess" type="text">no</value>
       <value name="Available" type="text">yes</value>
      </key>
The second agate added fine and is doing load balancing as well as we can see requests getting routed to both the agate in the load balancing screen. However we are not able to access the global.srvc file under configuration->Performance->global services->All settings as we are getting the following message:
Error loading service file "global.srvc"!
Also when we go to services under configuration, we are getting a message "error accessing services directory!"
In default R/3 system also all the fields are empty although we had given the application server details while installing both the agates.
We are getting the below messages in diagnostics.log file:

Please let me know if this procedure of adding the agate was wrong or there are some parameter settings that we may have missed. Would it have been better to go for a single host wgate+agate installation on host1 and then add agate2 on host2?

Hi Edgar,
Thanks for the reply. I had re-installed ADM instance on both the hosts after the whole exercise of installing agate and wgate.
Anyways, Now we have uninstalled the earlier instances on both hosts and installed wgate+agate on host1 as a single host installation and agate2 on host2. Then we added agate2 to wgate1 and load balancing is working fine. Now the issue of not being able to access the service file and directories, etc has also been resolved. The only problem that remains is that we are not able to go into the native ADM. We get a http 500 error, although the redirect URL is correct. Is the any additional setting required for that to happen?

ACE Load Balancing Problem

Hi,
I have ACE 4701 with c4710ace-mz.A3_2_2.bin image. In the current setup ACE is located in the center of network where all the WAN, Intenret and LAN is connected and ACE has default towards Internet and All other segment has default route towards ACE appliance. ACe is only redirecting the port 80 traffic to my Proxy server and bypass my lan subnet on port 80.

Please help me out what i am missing. Is there any limitation on policy map or my bypass subnet list is creating problem.

I did these changes this time nothing disconnected but I am not able to do the Remote desktop on the virtual IP address. Real IP has Remote desktop enabled even VIP is not ping able for me.

Load balancing problem

We need a load balancing setup that share the load for many web applications on multiple backend servers, but we don’t want the web apps to be activated on all backend servers at the same time. We want to configure all apps as “lazy” on all backend servers. They will then be activated when the first request to their DNS is made. Then the app is started on that backend server.
We have hundreds of apps and each backend server will become very slow if all apps are activated on all backend servers. The preferred solution would therefore be to not call all DNS names on all backend servers but to share the balance based on the DNS name in the requests. Sticky-session or sticky source-IP won’t be enough to solve this as they only stick to each user session.
If User-A request www.siteA.com he may be redirected to backend server 1 and then be kept there. But if User-B then requests the same www.siteA.com he may be redirected to backend server 2 and then be kept there. This means that the web application for siteA will be activated and loaded in both the backend servers. When we host hundreds of sites this will be a problem. We may have hundreds of backend servers but they will all end up loading all web apps over time and get out of memory.
The theory to get this work is a load balancer with the following logic:
1.     A request for a certain DNS comes in. For example: www.siteA.com
2.     Load balancer checks if this certain DNS has been redirected to a certain backend server before and if this server is alive
2.1.     (If not redirected before): Redirect the request to the backend server with least load. Store the selected backend route based on the DNS name.
2.2.     (If redirected before): Redirect the request to the assigned backend server for siteA.
3.     If a backend server is down then all DNS requests to this server will be redirected to another backend server with least load. All requests to these DNS names will be assigned to this backend server instead.
h3. Example of set up
Many DNS to one IP
192.168.1.1 www.siteA.com
192.168.1.1 www.siteB.com
192.168.1.1 www.siteC.com
Frontend load balancer
192.168.1.1 (load balancer)
Backend app servers
192.168.2.2 (App server 1)
192.168.2.3 (App server 2)
192.168.2.4 (App server 3)
h3. Snapshot of servers during load
App server 1
www.siteA.com (Activated)
www.siteB.com (Lazy)
www.siteC.com (Lazy)
App server 2
www.siteA.com (Lazy)
www.siteB.com (Activated)
www.siteC.com (Lazy)
App server 3
www.siteA.com (Lazy)
www.siteB.com (Lazy)
www.siteC.com (Activated)

Only from load balancing point of view cluster is not really needed.
apart from session replication and failover capabilities, few more benefits are there with clustering only if you are using a web server also.
Stuck threads can be due to lot's of problems like application issues, load issues etc, So first make sure you are getting stuck thread on both servers or only on one, if on one, then in this case your load balancing not working properly and sending more load to that server, and if you are getting stuck threads on both then try to add one more managed server.

Load Balance Problem in Oracle RAC 10.2.0.4 (two nodes with CRS)

Hi all,
I have an Oracle RAC 10.2.0.4 with two nodes and I'm having problems with sessions load balance.
The problem is that all connections are going to the node which is enabled as 'master' in RAC, the node who has located .db resource in CRS.
If .db resource is located in node1 all connections are made in node1. In the same way, all connections are made in node2 when .db resource from CRS stack is located in node2.
The connections are made by a pool in Tomcat 6 using RAC service for made the connections.
Any idea?
Thanks in advance.
Here is an example of my net configuration:
listener.ora in node1:
LISTENER_RAC_NODE1 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = node1_vip)(PORT = 1525)(IP = FIRST))
(ADDRESS = (PROTOCOL = TCP)(HOST = node1)(PORT = 1525)(IP = FIRST))
tnsnames in node1:
LISTENERS_RAC =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = node1_vip)(PORT = 1525))
(ADDRESS = (PROTOCOL = TCP)(HOST = node2_vip)(PORT = 1525))
NODE1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = node1_vip)(PORT = 1525))
(ADDRESS = (PROTOCOL = TCP)(HOST = node1)(PORT = 1525))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = rac)
(INSTANCE_NAME = rac1)
RAC =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = node1_vip)(PORT = 1525))
(ADDRESS = (PROTOCOL = TCP)(HOST = node2_vip)(PORT = 1525))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = rac)

It is my fault.
It was the connection service. I had one one with preferred option and one without it. Now is working well.

CSS load balancing problem

Hi,
I have two CSS that I use to load balance RDP connections to two WTS servers. I dont have switch behind CSS so they are connected back-to-back via cable. All server facing ports (including back-to-back ports) are in the same VLAN.
CSS1 is primary for the VIP address and for redundant interface address, and CSS2 is standby.
So, when I connect WTS-1 to CSS-1 and WTS-2 to CSS-2, CSS1 sees both services as active and everything seems fine. If WTS-2 is disconnected, WTS2 service on CSS1 is down etc.
In sticky table, I can see that CSS1 is load balancing request to both servers, but the problem is that only RDP connections to WTS-1(server directly connected to CSS1) work fine , and connections that are load balanced to WTS-2 are dropped??? Direct RDP connection to WTS-2 IP works fine.
If I connect WTS-2 to CSS1, so both WTS servers are connected to CSS1 everything works fine.
Can anyone tell what can be wrong?
Configurations are in the attachment.
Thanks for help.
Regards,
Branimir

try the command 'ip uncond' on both CSS.
It will guarantees that the response from WTS-2 comes back to CSS1.
Gilles.

Oracle RAC - Load Balancing Problem

Our J2EE application transactions (Container-managed) are using MULTIPLE database connections to complete one business transaction.
Recently we swiched to below Oracle RAC configuration, and it is creating problems.
BEA 8.1 SP5 Multi Pools
Oracle 9i RAC (2 instances) : Active - Active
Algorithm : Load Balancing
Driver (JDBC) : Oracle 10g Release 1 Thin Driver
non-XA transactions
Looks like when LB algorithm is chosen, the load balacing is only **connection-aware** and NOT **transaction-aware**. Because of this, the application gets one connection from one RAC instance, and other from other instance is creating problems.
Is there any work-around exist for this problem?
If we chose, HIGH_AVAILABILTY algorithm, everything is fine. But we would like to make use of both instances.

ChintalaHi, OK, that looks fine, except:
1 - I would define the initial and max capacity = 30, for performance and stability.
2 - For more performance, turn off test-on-release. It's a waste of cycles.
3 - You can change your TestTableName to "SQL BEGIN NULL; END;" which goes
even faster than "select 1 from dual".
And the main problem is:
4 - Your JDBCDataSource doesn't seem to be a transactional one, so any
application code that gets connections from that, will get independent
connections each time, and their work will not be included in any WLS
controlled transactions. You want to make/use a JDBCTxDataSource.

Weblogic DB connection pool load balancing problem

hi all,
here is a strange issue. We have a clustered weblogic environment with2 servers. And the application is deployed to cluster. But strangely when we check the active connections for the connection pool that is being used by the application, we see that 2nd server has more connections when compared to 1st server, lets say 1st server has 4 active connections, 2nd server has 50 connections, What might be the problem.

are you using any front end web server or hardware load balancer ? verify your load balancing if it's happening or not properly between your clustered managed servers.

Printer Pool load balancing problem.

We seem to be having a problem with printer load balancing working correctly. I have several computer labs. Each lab has at least 2 printers of the same type. As a result I pool the printers for each lab. We are still running ZCM10.3.4. Most of the clients are running iprint 5.82. With Zenworks 7 and 6.5 load balancing on these printers worked very well and page counts stayed very close on each printer. Now that we are at ZCM10 and have been for about 3 years now we continually see that one printer gets the majority of jobs. Most of the computers are imaged but printers are installed after imaging. Even if we alternate the default printer on the computer print jobs still mostly come out the same printer. All printers except 3 are HP and in our case they are all new HP M602's with a couple older HP4015DN's thrown in when the new HP M602's would print garbage across the wan and the 4015's would print correctly but that is another topic.
Am I misunderstanding how load balancing is supposed to work? Isn't load balancing supposed to be one of the features of printer pooling in addition to sending jobs to the printer that is not busy at the time the job is sent? How is load balancing set up?
Thank you.
