LRT224 Load Balancing Servers

I get the process of load balancing outbound traffic, and even protocol binding so that servers send out traffic only on a specific WAN port. What I do not get is how to load balance INBOUND traffic also to those servers and ensure that the servers response goes out on the interface that it originated.
I have two 50mb internet connections from different ISPs. Each with a static IP address.
The web server is on a private IP address with appropriate forwarding.
The web server IP address is bound to WAN2 which is the DNS address of the web server.
All works perfect. Outboud traffic from the web server exits from the appropriate WAN port while residual traffic is load balanced.
Now, I want to add an A record to the DNS for the web server so that INBOUND traffic ot he web server is balanced and providing a redundant service. However, the protocol binding should not allow any outbound connection through WAN1. Right?
So my question is, is this setup impossible? Do we forget the protocol binding and hope that the outbound responses from the server exits through the originating port? Is there another method? Or, do I need a more advanced router?
I do not even want to consider DMZ even as this is impossible since I am utilizing both ports as WAN ports. Anyone have any suggestions to do this?
Thanks
Mark

Sorry I misunderstood.
IMO for this to work on an LRT224 you would need:
A second network adapter in the Server and the Server configured to answer requests on both NIC's
Protocol Binding the second Server NIC to the other WAN port
A DNS Hosting Service that support DNS Round Robin or you would run your own DNS Server with Round Robin DNS capabilities
These days I'm seeing DNS propagation with namesecure only taking a few hours instead of the advertised 96hrs.

How to configure RZ12 and SM59 ABAP connection settings when we have work with Load Balancing servers rather than a specific server .

Hi ,
If we have a specific server say 10.10.10.10 (abc.co.in) on which we are working, Then under RZ12 we make the following entry as :
LOGON GROUP          INSTANCE
parallel_generators        abc.co.in_10         ( Lets assume : The instance number is 10 )
Now in SM59 under ABAP Connections , I am giving the following technical settings:
TARGET HOST          abc.co.in
IP address                  10.10.10.10
Instance number          10
Now if we have a scenario of load balancing servers with following server details (with all servers on different instance numbers ) :
10.10.10.11
10.10.10.13
10.1010.10
10.10.10.15
In this case how can we make the RZ12 settings and SM59 settings such that we don't have to hardcode any IP Address.
If the request is redirected to 10.10.10.11 and not to 10.10.10.10 , in that case how will the settings be.

Hi,
No one using FMS behind a load balancer? No one using RTMPT?

LRT224 Load Balancing with only one ISP

I found that the LRT224 Load Balancing really increased performance on my network with a single Internet Service Provider.
Also if your ISP doesn't limit the number of Public IP Addresses your ISP Device can provide to one. You can get two Public IP Address for additional port forwarding and other uses.

In my case I noticed an immediate improvement in overall performance. When I do a "speedtest.net" test the speeds are always at the maximum throughput even with other heavy users on the internet. Which wasn't the case before. I suspect that the Dual WAN connections are doubling the amount of available full speed connections due to the load balancing.
It's interesting to watch the ethernet port lights on the ISP Modem blinking like mad as the LRT224 pumps data through the two ethernet ports.

ACE load balancing servers on different subnets...

Hello,
I have the following issue.... need to load balance traffic between two servers already working in two different subnets (vlans), at this point is highly desirable to avoid changing IP addresses. Is it possible to accomplish this goal using ACE? routed or bridged mode? is it strictly necessary to have all servers belonging to a serverfarm in the same subnet?
Thanks in advanced for your support.

Hi,
You can do this, but you have to use client-NAT (Source-NAT) to force the return traffic to pass back through the ACE. You also then need static routes in the ACE context to point at each server. PBR is an alternative approach but I have not implemented that in a live network. The important thing is that the ACE sees both sides of the conversation.
The following extract from a configuration shows the basic principle:

Load balance servers with 3560?

Here is my scenario...
I have two servers that are both connected to a single 3560 (SMI).
These two servers are in a primary/secondary relationship. Right now, if the primary server goes down - we need to manually configure the secondary server to take over.
I have two questions...
What is the best way to set up fault tolerance with these devices, so the secondary server will automatically kick in if the primary goes down?
In addition to that, is there any type of load balancing feature we can use on this 3560...so both the primary/secondary servers can run at the same time?
Ideally, we would like communication to the second server kick in when the link to the primary server gets too congested.

your best bet is to use IOS SLB or a content switch such as the cisco CSS series.
please see the following links for more info on ciscos CSS and SLB capabilities:

ACE: load balancing servers using DMZ ports on FWSM

devices; (2 core with the ff config)
6500
fwsm
idsm
msfc
SETUP;
Servers are connected to the dmzs on the core
REQUIREMENT;
to load balance the servers
QUESTION;
Using the ACE module, is it possibe to load balance the servers which are connected to the port which is configured as DMZ?
Thanks

does not matter where the servers are connected.
However, be aware that the flows from client to server needs to go through the loadbalancer BUT also the flows server to client.
So, you should be careful where you attach the ACE module.
The easier would be to attach to the DMZ as well between the FW and the servers.

LRT224 Load Balancing and Link Failover

Hi, I am new to this forum. I have recently set up the LRT224 with two different ISP's. I am having problems configuring the Load Balance and Link Failover.
When I have Load Balance selected only one ISP (WAN 1) is active, the other (WAN2, ISP modem) remains inactive. Why is Load Balance only engaging one ISP?
When I have Link Failover selected, even with attempts and seconds configured to one second, and WAN1 has packets lost, it doesn't switch over to WAN2.
I am not tech savey but any help will be greatly appreciated so that I can get both ISP's active with Load Balance or at least have Link Failover work almost instantly. Thanks.

Hi @BSue2015,
If both WAN1 and WAN2 are already getting IP Addresses from your ISPs then we can say that Load Balance is working. To check it further, do a speed test by going to http://www.speedtest.net. Dual WAN connections are doubling the amount of available full speed connections due to the load balancing. The speed should have its maximum throughput even if you have several users on the network.

LRT224 Load Balancing

Hi there just wondering can the LRT224 handle load balancing a 130/7 and 107/30 connection. Thanks

Hi @Spencer1990,
I agree with Chadster. It should be able to. According to the Specifications of the LRT224 router, IPsec VPN throughput (110 Mbps), Maximum NAT throughput (900 Mbps), Maximum concurrent connections (30,000).
I got it from this link: http://www.linksys.com/en-apac/business/products/routers/lrt224
Thank you.

LRT224 load balancing, switching between circuits "resets" secure sites

We have noticed a problem with certian secure websites when load balancing is enabled on the LRT224. The company has a DSL and cable circuit, static I/P's on both. Running Speedtest shows a 30m pipe with load balancing enabled, about 16m on each when off. When utilizing load balancing, if accessing banking, government or otherwise more secure sites, those pages will reset to the login consistently. If turning off load balancing and picking either circuit, this does not occur. We have 2 identical LRT224's and the both do it. I have contacted Linksys customer support to no avail. Firmware is up to date. This is entirely replicateable on both units and very consistent. Any help would be greatly appreciated. Chris

chadster766,
i have updated the firmware as directed and the result is the same. as i indicated, it's easily reproduced by just switching the router to a single circuit (fail over mode) and those sites do not reset. i have 2 exact units and they both perform the same. for a quick fix, i just turn off load balancing, perform the banking functions and then return it to load balancing. not hard just doesn't seem this revision addresses the problem but thank you for the assistance to date.Did you enable Sticky Load Balancing?Use the below link to make sure the feature is functioning properly.

How to remote deploy across load balanced servers

I have a server farm that is load balanced, how would I deploy to 15 servers at the same time? Or what is the process to do such a thing using SJWS?
Doing it manually one at a time just doesn't make sense...

Hi,
this is a known issue as you will be executing 2 report requests, one to execute the report and the other to retrieve and display the report, in this scenario the second request( to do the display) is forwarded by the LBR to the reports server where the request was NO executed so the error you are getting is expected.
To resolve this please check the following notes.
Rep-52251: Cannot Get Output of Job Id###, when Calling Reports from Forms (Doc ID 367887.1)
Maintaining 6i Run_Report_Object Code in 10.1.2 Without Employing Clustering/HA (Doc ID 358436.1)
Regarding the second question the issue I think is related to cacheSize and/or maxCacheFileNumber settings in your reports server configuration file.
Hope it helps.

LRT224 Load Balance "dumb" DHCP router setup... HELP!

Hi
I'm trying to set up a LRT224 with two ADSL modems connected to one network with load balancing.
I'm not going to use vlan or vpn at all.
All I need it to do is be a "dumb" router that combines the speed of both Internet connections.
Working mode is set to Router
LAN 192.168.0.1/255.255.255.0 (I changed the LAN ip range)
WAN 1 and 2 gets IP, default gateway and DNS trough DHCP from the modems.
Wan 1: IP 192.168.1.65 Gateway 192.168.1.1 DNS 192.168.1.1
Wan 2: IP 192.168.2.38 Gateway 192.168.2.1 DNS 192.168.2.1
DHCP setup:
Device IP: 192.168.0.1
Subnet: 255.255.255.0
DHCP Server
Range 192.168.0.50/254
DNS: Use DNS from ISP
Dual Wan:
Load Balance
I'm no IT expert at but I have set up a few routers before that was close to "plug and play"
My problem is that connected computers indicate that they are connected to Internet, but I'm not able to access any websites.
When trying to use windows troubleshooter it indicates that there is a DNS problem.
I'm not even able to connect to the modems.
Installed latest firmware and done a fabric restore.
Network is built as follows (still working as I'm not running anything trough the lrt224 before I can get it to work)
ADSL Modem with built in DHCP and Switch --> Switch --> Ubiquiti Unifi AP --> User
Some of the AP's is connected via Ubiquiti NanoStation (wireless bridge between 4 houses, works great)
Any idea how to get this to work or do I have the wrong router?

I recommend:
Modem1 (192.168.1.1)=> LRT WAN1 (192.168.1.254)
Modem2 (10.10.10.1) => LRT WAN2 (10.10.10.254)
LRT WAN1 SN (255.255.255.0)
LRT WAN2 SN (255.255.255.0)
LRT WAN1 GW (192.168.1.1)
LRT WAN2 GW (10.10.10.1)
LRT WAN1 DNS (192.168.1.1)
LRT WAN2 DNS (10.10.10.1)
System Management => Load Balance
LRT DHCP Device IP (192.168.200.1)
LRT LAN => Switch => Ubiquiti Unifi AP => User
Nothing other than the LRT's connected to the modems.
If the modems DHCP is set to 192.168.1.x and 10.10.10.x subnet 255.255.255.0 then DHCP setting will work on the LRT WANs.

ACE 4710 multiple services running on load balanced Servers

Our Exchange 2010 hub servers run multiple services/ports: smtp, www, pop3,135, 143, https, 993, 995, 6001,6002,6003,60200,60201,8400, and 8402
what is the best way of balancing these servers so that if only one of the services failed on a server, it would switch only the failed service to remaining servers.
At present I only use an smtp probe, so as log as that sevrice is running the server is marked good. It seems to me the setup could get quite complicated so any responses welcome.

Office Web Apps Load Balancing Configuration Issue for SharePoint 2013

I have load balanced servers dedicated for Office Web Apps with name “md1xxxwfe1” and “md1xxxwfe2”
, both this servers are load balanced by CISCO Load balancer. And I have mapped Load Balancer Virutal IP with host name officeapps.jda.corp.local in the DNS records.
Things are working fine if I add new farm by using New-OfficeWebAppsFarm
with server name as internalurl in PowerShell console
as like “ -internalurl http://

Thanks, Ram Ch

Hi Ram ,
For troubleshooting your issue, please take steps as below:
Just about any load balancing solution will work, including a server that runs the Web Server (IIS) role running Application Request Routing (ARR):Install
Application Request Routing
Install the certificate on the load balancer as described under Securing Office Web Apps Server communications by using
HTTPS.
Make sure you have configured the cluster correctly for full internet name:

Load balancing server names

My Application is handled by three load balanced servers.I have a functionality in which first i send a request for a document printing.This request is posted in Database.Then a backend script runs and takes each requets in DB and executes and creates a file and places in server space. This works fine when i have only one server.But when i have load balanced servers user can give request for print from one server(he does know where from he is giving) and backend shell scripts can take the OPEN record from DB and execute in another server.So user is not able to find the document thought his request is processed.I have tried to know the DNS names of teh server whose are taking the print request so that i can track. But when i check with ServletRequest.getServerName() but i always get the application URL not teh specific load balance server name. I am tryong my luck with java.net.InetAddress

Hey i could solve this problem. i have used java.net.InetAddress class and its methods to know the system name on which my code is executing.

2) I presently have a static route in my core router "ip route 10.15.15.0 255.255.255.0 19.10.28.210". (this enables the load-balanced servers to connect to Oracle servers on the Core network). do I need to configure a new route on my core router when I add the additional vip 19.10.28.215?
relevant references and/or examples will be much appreciated.
dayo

1/ configure the following :
service web1
ip address 10.15.15.25
active
service web
ip address 10.15.15.26
active
content WEB
vip address 19.10.28.215
proto tcp
port 80
add service web1
add service web2
active
2/ I would create a redundant-interface and point your static route to this redundant ip address.
you should not use vip address in static route.
VIP address should only be used when you want to reach the vip address not a when you want a direct connection to the real server.
