Firewall Load Balance using bridged mode ACE
Dear Folks,
I 'd like to load balance 2 ASA using 3 ACE [ Inside,outside,dmz network zone]
I 've seen sample configuration, all of them are running the ACE in the route mode, and asa are running in route mode
Would it be possible to run the ACE in the bridge Mode, because the ip subneted problem, We don't have enough to split,,
by the way if possible,All server that install behind ACE, what is default gateway should Server Point to [ in our case we have 2 independent firewall ] should I create the VIP for both firewall ? or should I just simply set the server's gateway to BVI interface, ?
Please Help Thanks
Thank you very much Gilles,
You 're the man. ;-)
Another question in my case I try to load balance 3 interface firewall [inside,outside,dmz] in order to make the packet return the same firewall it has passed earlier,
What kind of hashing technique do I need to use and Do i need to use mac sticky command ???
I tried to find some configuration sample from cisco website , but i only found with only 2 interface with ACE running source hash and destination hash in each ends,
Thank you very much

Cisco ACE - Firewall load balancing
I am using two sets of ACE load balancers for load balancing traffic across two firewalls (firewall load balancing).
The solution works fine. I have a virtual address of 0.0.0.0 in either direction to match traffci going from the internal users to the internet and vice versa.
The problem is that when I try to manage the load-balanced firewalls (either using SSH (or) HTTPS) from outside, then that connection also gets load balanced and when I try to connect to FW1 then sometimes this connection ends up on FW2 and vice versa and the connection gets dropped. I have a workaround in place where i am using a virtual address per firewall to connect to the real IP address of the firewall.
Is there any other way of managing firewalls (which are defined as real-servers) in a FWLB setup.
Attached is the configuration of the external ACE which has the two firewalls defined as the real-servers.

How can ftp service on non-standard port be load balanced using Cisco ACE.
How can ftp service on non-standard port be load balanced using Cisco ACE.For example ftp service required on tcp 2000 port
Hi Samarjit,
you can do this by specifying the port number in the class map that you create . Please find the below mentioend config guide where you can specify the tcp/udp port , range or ports or even the wild card to match the port.

When i do FTP from client 10.20.10.101 , my connection is getting refused.... But when i connect to my server directly bypassing ACE i am getting authenticated ..
As per the DSR , i made Rserver & ACE as L2 Adjacent , so when ACE receives the packet it will change the dest ip instead it will use VIP ip as destination , but the MAC will be rewritten to Rserver MAC address... As i said before all works fine for http DSR ...
I know NAT doesn't work in ACE when its configured under DSR , but for FTP i made NAT config , but even if i remove the same its not working , Is my config for FTP is correct ?
Could some please look into this and reply ?
Thanks
Charlesif you need to route / provide load balancing between 2 hosts, then you will need to have Route SAF . you can use web server 7 reverse proxy cli or gui to get this. however, you might want to start from a fresh configuration to avoid reverse-map / map that you have experimented with does not overlap with the 'Route' functionality that you seem to need here
here are some reference content

IDSM-2 load balancing on inline mode is it possible ..?
Hi there .. I am currenty working on a project and need to find out as to whether etherchanelling load balancing can be configured between several IDSM-2 running on inline mode. The IPS 5.1 admin guide states that it is possible for IOS based switches having the IDSM-2 configured on promiscuous mode, however I have heard that it might also be possible to configure etherchannelling load balance when the IDSM-2 are on inline mode. Any help .. commments will be appreciated .. any links to refer to will be even better
Thanks !!!To configure EtherChannel load balancing on IDSM-2, you must install Cisco IOS 12.2(18)SXE and have Supervisor Engine 720. Cisco IOS only supports promiscuous IDSM-2 EtherChanneling using VACL capture (not SPAN or monitor). Refer the URL

Load balancing UDP application in ACE
Hi all,
What's the proper way to load balance a UDP application (NTP protocol) using ACE? We used to do it in our CSS using a content to load-balance and a source group to source-NAT the UDP replies from the servers to the VIP. I guess this should be implemented using NAT in the ACE, but I can't find any example.
According to the manual, src-natting to VIPs is supported only in A1(8) and it is supposed to be used "when there is a limited number of real-world IP addresses on the client-side network".
This is not our case, we just need to ensure that the client receives the UDP replies as coming from the VIP, not from real IP address of the server. This is not a problem in TCP-based applications, because the NAT from the rserver IP to the VIP is automatic. What is the proper way to obtain this behaviour for UDP applications? Thanks a lot!
Regards,
PedroPedro,
reverse nating is not required in ACE world.
This is done automatically.
So, the server response will be automatically nated to the vip address when going back to the client.
If you have an appliance and are just deploying now, I would recommend version A3(2.1).
If you have a module go for A2(1.3).

CSM - Load balance using Server CPU
Hi
I have a customer who requires the load-balancing prediction
algorithm to be based on the CPU level of the Server. So the server with the least CPU is chosen at the laod-balancing stage.
Is there a way to do this?
Thanks JamesHi James
With CSM the only option is DFP (Dynamic feed back protocol). If your application vendor provides DFP agents (which is very unlikely) for the application then these agents can be installed on App servers for the desired purpose.

With ACE you can use SNMP based probes to achieve what you are looking for.

Adding a 2nd WFE to a Production Farm - Load balanced using F5 Virtual IPs
Hello all,
In much reading I haven't been able to find a more or less straight answer to this question: I have a small-ish SharePoint farm; 1 WFE, 1 App and a SQL cluster. I need to bring a 2nd web front end into the farm. What I am trying to find
out is, may I install the SharePoint bits and join the new web front end to the farm - without putting the web apps' IPs into my F5 pools - without adversely impacting the farm?
What I'm after is time to test the new web front end by redirecting my browser to it via my hosts file. Once I'm confident all is well, I would then configure WFE2 to have traffic forwarded to it through the F5. Is this a reasonable hope?
Thanks in advance for any advice you might provideYes, that will work.
Having an extra WFE that isn't included in your load balancer is actually a fairly common practice when you use it as a dedicated crawl target, there' no impact to having it there unused for a while.
Thanks very much for confirming; I appreciate that! -
Dear All,
I need to built a scenario where i am using two ISP's for redundancy for my internal network and at the same time wants to load balance in such a way that my first packet going outside the network (using NAT) goes from first ISP's public ip address and second packet going outside the network (using NAT) goes from second ISP's public ip address.
Need your help

Load balancing using multiple default routes
Hi Guys,
I just want to ask does creating multiple default routes on my router provides load-balancing on my WAN side? As far as i know, for example if I have two default routes on my router and let say I have two users connecting to the internet, the first one might go to the first WAN link while the second user might go to the second WAN link.
Thank you so much
Rexthere are the difference between, load balancing and load sharing..which we need to understand.
load sharing means you have 2 users, user A and User B, user A wants to use ISP1 and user B wants to use ISP2. this is called load sharing. and can be achieved via PBR (Policy based routing).
we should not try to use load balancing for Internet traffic with 2 different ISPs. -
Load-balancing using ServerIrons or NetApp Netcaches
Dear all,
From a cursory search, this one has been asked loads of times, but I can't find
an answer....
We're adding a Weblogic cluster into a resilient environment which has Netcache
boxes doing reverse proxy and content caching, and Foundry ServerIrons doing the
load-balancing. We could add in a pair of Apache servers load-balanced by the
serverIrons and a pair of weblogic boxes in a cluster. However, this is not only
a bit of overkill, but also adds quite a bit of latency to requests. We also
already have the Netcache boxes. So, we want to get rid of Apache, and use a
proposed 3 tier environment:
Netcache
|
| (possibly via a serverIron)
v
Weblogic Cluster
|
|
v
Oracle
Will this work? Does anyone have any experience extracting the session ID on
a serverIron (or even on a netcache itself)? Has anyone found a way of doing
session failover using a serverIron?
Words of wisdom are needed for a flagging technical consultant...
Thanks

Load Balancing using Virtual IP on DMZ interface of 5520 ASA
We want to achieve a load balancing scenario using Virtual IP on DMZ interface on a Cisco ASA 5520.
The IPs we are going to use on DMZ are 10.15.1.2 and 10.15.1.3
These IPs are going to be NATted to all inside IPs.
Lets say our outside IP is X.X.X.X
This IP points to 10.15.1.2 and 10.15.1.3 with .2 being the primary and .3 being the secondary.
When I hit the outside IP, it should point me to .2 and that .2 should take me to the inside IPs.
I need configuration assistance with that.Hi Pratik,
The ASA does not support having 1 global/translated IP address on the outside mapped to multiple local/real IP addresses on the DMZ. If it did, the ASA would have no way of deciding if traffic destined to X.X.X.X is really meant for 10.15.1.2 or 10.15.1.3. For this scenario, you should use a dedicated load balancer or a router that supports policy-based routing.

Using "bridge mode" to extend a network question
I had been using my TC as my only wireless router. I recently obtained FiOS service and they provided me with a router that is working just fine. That router is in the basement. The house is wired for internet so I connected the TC upstairs thinking I could use it to extend the signal.
I put it in bridge mode but even when I'm in the same room my connecting devices don't show a very strong wireless signal. I'm wondering if I've set it up correctly.
I noticed when I go into the airport utility that wireless mode is turned off. Is this correct for what I'm trying to do?
If I turn on the option to "extend a wireless network) I'm not sure if I'm supposed to enter the name of the network currently assigned to my other router. A password is pre-filled in there it looks like but perhaps that from when I used to the TC by itself.
Under the "internet" tab, I have "connection sharing" set to "off-bridge mode." I think that's correct, yes?
Thanks.Bridge mode is the correct setting for Connection Sharing on your TC, but you need to configure your wireless on the TC to "Create a wireless network" with the exact same name (SSID), security and password that the FIOS router is using. This will, in effect, expand your network. Your laptop will automatically connect to the device with the strongest signal as you move around the house. This is known as a "roaming" network, and it is the basic network design behind most commercial wireless installations.
The "extend a wireless network" setting is only used if you have another Apple "n" router as your main base station and you want to expand the network using wireless only, not ethernet. The "extend" setting would not be compatible with any of the FIOS routers, so you would not be able to use this setting on your network.
