ACE 4710 : Disable NAT

Hi All,
Currently Im using nat to translate client source ip address, nat pool is configured on server side vlan interface.
but now I dont want to translate client source ip address:
-I have changed real server gateway to ace interface ip.
-I already remove nat configuration but now I cannot access to the vip using browser but I can ping vip.
But now I cannot access to vip through browser, any idea?
Design:
client--------------CORE--------ACE------------------Real Server.
Thanks

Need help/advise regarding routing to make this method working.
When I change server gateway to ace server vlan interface, my server cannot communicate with other vlans. From context, I can ping server vlan and other vlans.
*Core interface -172.16.36.254 (server vlan),172.19.30.254(client vlan).
*Lb interface - 172.16.36.70, 172.19.30.65
*Real Server ip is using default gateway 172.16.36.70
Routing what I have done:
CORE- ip route 172.16.36.0 255.255.255.0 172.16.36.70
ip route 172.19.30.0 255.255.255.0 172.19.30.65
LB- ip route 0.0.0.0 0.0.0.0 172.19.30.254
Can someone help me to verify this?
Thanks

ACE 4710 client NAT (outgoing)

Hi Experts,
     I have a ace 4710 set as load balancing http and https only, seems working fine.
     Now I have another requirment to NAT all real servers IP (server side internal network 10.8.8.0) to VIP (192.168.1.20).
our configuration is as below,
two real server ip are 10.8.8.2 and 10.8.8.3 connected to VLAN interface v500 (ip is 10.8.8.254)
vlan v400 face to public, v400 interface ip 192.168.1.10, and one VIP 192.168.1.20, VIP is mapped to two real servers.
I need to config: all outgoing trafic from network 10.8.8.0 to public to NAT the source IP to 192.168.1.20 (VIP, not the interface real IP 192.168.1.10).
Thanks,
BQ

Here are a few things you could try
1. nat-pool 5 192.168.1.20 192.168.1.20 netmask 255.255.255.0 pat
changeto
nat-pool 5 192.168.1.20 192.168.1.20 netmask 255.255.255.255 (/32 host)
2.service-policy input remote-access
do you have a management Vlan interface defined if so add to that interface
3. The requirements are to LB http (80), and https (443). In this case you would need two seperate VIPS defined
VIP1:
class-map match-all slb-vip
2 match virtual-address 192.168.1.20 eq tcp 80
VIP2:
class-map match-all slb-vip
2 match virtual-address 192.168.1.20 eq tcp 443
Is there a requirement to redirect http traffic ? If so you would need to define another class-map to redirect http traffic to https

ACE 4710 Disable server

Hi again!
Some say that there is a script command, that can disable a server when we want it. It's something like "disable_real" , but i haven't found anything about it... can anyone help please?

Rservers initiated traffic not sourcing the traffic as VIP in Ace 4710

One of the feature of our application is that our Application Server initiate text message to our devices sourcing from UDP 1120 and device need to see the message come from a specific pubic IP (2.2.2.2) with UDP port 1120 and reply back with the same Public IP (2.2.2.2) with UDP port 1120.The problem is we can make that happen if we have only one server in our ACE Serverfarm when we do a SNAT the real servers with the VIP address (10.1.246.32) but it does not work when we have more than one server in the Serverfarm. Since we have 2 servers, i cannot nat the real servers with the VIP address, if I do a PAT, obviously it is changing the source port of the request.
Note: This setup is working fine with the Cisco Content Switch module running on chasis 6509. When I sniff the traffic initiated from the server coming the CSM load balancer, it is sourcing the traffic as the VIP and the source port remains the same by default but this is not the case with ACE 4710
Traffic flow as follows

I see in CSS, they are able to nat the source ip address with VIP and port-mapping diabled. How do I implement
portmap disable in ACE 4710
Disabling Port Mapping
By default, the CSS NATs source IP addresses and PATs source ports for a configured source group. If you configure the portmap disablecommand in a source group, the CSS performs NAT on the source IP addresses but does not perform PAT on the source ports of UDP traffic that matches on that source group.
For UDP applications with high-numbered assigned ports (for example, SIP and WAP), we recommend that you preserve those port numbers by configuring destination services in source groups instead of using the portmap disable command. Destination services cause the CSS to NAT the client source ports, but not the destination ports. For information about configuring destination services,

Need help to Configure Cisco ACE 4710 Cluster Deployment

Dear Experts,
I'm newbie for Cisco ACE 4710, and still I'm in learning stage. Meanwhile I got chance at my work place to deploy a Cisco ACE 4710 cluster which should load balance the traffic between two Application Servers based on HTTP and HTTPS traffic. So I was looking for good deployment guide in Cisco SBA knowledge base then finall found this guide.
http://www.cisco.com/en/US/docs/solutions/SBA/February2013/Cisco_SBA_DC_AdvancedServer-LoadBalancingDeploymentGuide-Feb2013.pdf
This guide totally fine with my required deployment model. I have same deployment environment as this guide contains with ACE cluster that connects to two Cisco 3750X (Stack) switches. But I have some confusion places in this guide
This guide follow the "One-armed mode" as a deployment method. But when I go through it further I have noticed that they have configured server VLAN as a 10.4.49.0/24 (all servers reside in it) and Client side VIP also in same VLAN which is 10.4.49.100/24 (even NAT pool also).
My confusion is, as I have learned about Cisco ACE 4710 one-armed mode deployment method, it should has two VLAN segments, one for Client side which client request come and hit the VIP and then second one for Server side. which means besically two VLANs. So please be kind enough to go through above document then tell me where is wrong, what shoud I need to do for the best. Please this is an urgent, so need your help quickly.
Thanks....!

Dear Kanwal,
I need quick help for you. Following are the Application LB requirements which I received from my clinet side.
Following detail required for configuring Oracle EBS Apps tier on HA:
LBR IP and Name required to configure EBS APPS Tier (i.e, ap1ebs & ap2ebs nodes)
Suggested IP and Name for LBR:
IP : 172.25.45.x [should be on same 172.25.45 subnet of ap1ebs & ap2ebs nodes]
ebiz.xxxx.lk [on port 80 for http protocol accessibility]
This LBR IP & name must be resolve and respond on DNS network
Server Farm detail for LBR Setup
Following detail will be use for configuring the LBR:
LBR IP and Name :
IP : 172.25.45.x [should be on same 172.25.45 subnet of ap1ebs & ap2ebs nodes]
ebiz.xxxx.lk [on port 80 for http protocol accessibility]
This LBR IP & name must be resolve and respond on DNS network
Server Farm Detail for LBR setup:
Server 1 (EBS App1 Node, ap1ebs):
IP : 172.25.45.19
Server Name: ap1ebs.xxxx.lk [ap1ebs hostname is an example, actual hostname will be use]
Protocol: http
Port: 8000
Server 2 (EBS App2 Node, ap2ebs):
IP : 172.25.45.20
Server Name: ap2ebs.xxxx.lk [ap2ebs hostname is an example, actual hostname will be use]
Protocol: http
Port: 8000
Since my client needs to access URL ebiz.xxxx.lk which should be resolved by IP 172.25.45.21 (virtual IP) via http (80) before they deploy the app on the two servers I just ran web service on both servers (Linux) and was trying to access http://172.25.45.21 it was working fine and gave me index.html page. Now after my client has deployed the application then when he tries to access the page http://172.25.45.21 he cannot see his main login page. But still my testing web servers are there on both servers when I type http://172.25.45.21 it will get index.html page, but not my client web login page. What can I do for this ?
Following are my latest config :

Cannot Telnet to ACE 4710 after upgrade to A4(2.3)

I have a pair of ACE 4710s with 12 contexts sharing the load, running A4(2.1). Yesterday I upgraded one of them to A4(2.3)
now I cannot telnet to the Admin context.Pings ok. I can telnet to other contexts on the box and everything seems to be working ok
when i do a " sh telnet"
comes back with
No Session Information is available
sh telnet maxsessions
telnet maxsessions 16
Can anybody help?

further this post, it was not a resource problem as had allocated 5% for the Admin context.
I up graded IOS Saturday evening, could not Telnet in, tried again on Sunday same result,
though this morning (Monday) Can now telnet in ok very strange
I was connecting via the AUX line of a 2851 router to the console port.
whe I disconnected this morning I saw the following message
INIT: id "T0" respawning too fast : disabled for 5 minutes
not sure if this is a 2851 message or an ACE message, but after getting that message is when I was able to Telnet in
was it a coincidence
anybody any ideas

ACE 4710 in bridge mode not working

I am trying to configure ACE 4710 bridge mode and I am stuck up in physical interface configuration. I have configured gig1/2 of ACE as trunk port and on layer 2 switch I have assigned that interface (gig1/2) to VLAN 11. I tried trunk port also but it got disabled due to BPDU error.

" I tried trunk port also but it got disabled"   <----- if your L2 config is not correct, nothing will work.
What is the setup on the switch ? Trunk or access vlan ?
What is the status of the interface ? up ? down ?
Do you see something in your arp table ?

ACE 4710 Connectivity help?

I'm using an ACE 4710 in a new datacenter, with the following setup:
2/4 physical ethernet interfaces port channeled into port-channel 1
2/4 physical ethernet interfaces port channeled into port-channel 2
I have the following vlans defined:
1001 - admin - interface ip: 10.53.136.70
400 - client side - interface ip: 10.53.136.100
500 - server side - interface ip: 192.168.128.1
999 - fault tolerance - interface ip: 192.168.11.2
My problem is I am trying to nat ssh and web server traffic from the client side, to the server side, but it's never getting to the server. For example, if I ssh to 10.53.136.102, it times out. (10.53.136.102 should get nat'd to 192.168.128.2)
Also, I can connect to the ACE 4710 via telnet using 10.53.136.70, but cannot connect to 10.53.136.100.
I'm thinking there is either something wrong with the port-channels, or the access lists. On the other hand there could be something wrong with the nat'ing, but I had it working before switching over to the port-channels.
Any thoughts?
Thanks,
Brent

I've attached the two contexts which we are using. The admin context is new_lb_config.txt and the second context where the loadbalancing occurs is in the new_lb_config_VC_WBPX.txt file.
From the load balancer, I am able to ping the real server ips in the 192.168. ip range. The 4710 recognizes that they are in service.
I believe the ACL for the VLAN 400 is set to permit all traffic, but I don't know if the service policies are preventing something from happening.
Right now, I have disconnected the two 4710s and I am only working on one of them to see if I can get the basic connectivity going. Once I accomplish that, I will work on high availability. I'll have to check whether it thinks it is in passive mode...not entirely sure how to do that, but I will check it out.
Thanks,
Brent

ACE 4710 - Internet Explorer cannot display the webpage randomly

We have a ACE 4710 with a basic config, (see below).
When clicking on a tab from a window within Interent explorer we occasionally get an issue with it returning: "Internet Explorer cannot display the webpage" The details show "Access is denied" accessing a particular line of a javascript file.
We have put one web server out of service in the farm to make sure that this isn't a result of stickyness not quite working.
We have tested extensively by going directly to the web server directly without the load balancer and cannot reproduce the problem but we can produce the issue within a few minutes when going to the load balanced address.
Thanks in advance for any advice.

ACE 4710 Pls need help

Hi,
Pls can you help me find out where is my error in the below:
I have an ACE 4710. Also I have 2 Bluecoat Proxy SG working in proxy mode. I want the ACE to be the Load Balancer for these 2 Proxy SG. I configure the ACE as below and put the vip-address in the Internet Explorer LAN Settings but it did not work. Also I configure Policy-based Routing on the Core Switch (for any http or https traffic going through core apply set ip next-hop vip-address).

Add two servers with ACE 4710

Dear All,
We have two servers (sharepoint ) and need to add it in ACE 4710 to works as internal no need WAN , how to add it ?
Thanks a lot in Advance

Hi,
Here's the example:
Let's say you have two servers
rserver host SERVER_01
ip address 192.168.1.11
inservice
rserver host SERVER_02
ip address 192.168.1.12
inservice
rserver host SERVER_03
ip address 192.168.1.13
inservice
You add them in serverfarm
serverfarm host REAL_SERVERS
rserver SERVER_01
    inservice
rserver SERVER_02
    inservice
rserver SERVER_03
    inservice
After that you configure the VIP and condition. Here any means any protocol and port
class-map match-all VIP-30
2 match virtual-address 172.16.51.30 any
YOu define the L7 policy map
policy-map type loadbalance first-match SLB_LOGIC
class class-default
    serverfarm REAL_SERVERS--------->Serverfarm to which traffic would be loadbalanced.
policy-map multi-match CLIENT_VIPS---->L3 policy map.
class VIP-30
    loadbalance vip inservice
    loadbalance policy SLB_LOGIC
    nat dynamic 1 vlan 451----------------->You need to apply the NAT when your client is in same subnet as server so that return traffic comes back to ACE and not to client directly.

ACE 4710 is not working

Hi. I'm working on the Cisco ACE 4710 to be able to load balance web Traffic between several web servers. but despite following the steps mentioned on the Cisco configuration guide (specially this link and related docs: http://docwiki.cisco.com/wiki/Cisco_ACE_4700_Series_Appliance_Quick_Start_Guide,_Release_A3(1.0)_--_Creating_a_Virtual_Context) we did not managed to make it. we tested both the "bridged scenario" and "routed scenario" but none of them is working. specifically "configuring Nat" in the above link is very confusing and is not clear; because it's not the same as Cisco IOS, which we used to implement it that way.

Hi,
Let me explain you.
Assuming client IP as 1.1.1.1, VIP as 2.2.2.2 and Real Server as 3.3.3.3
Consider the simple situation where client needs to access an application hosted on 3.3.3.3. Client sends a request which comes to VIP.
src 1.1.1.1----->dst------->2.2.2.2. ACE after matching conditions and taking LB decision decides to send it to 3.3.3.3 real server. Performs destination NAT and forwards the client request to 3.3.3.3. So the above packet L3 header will now look like:
src 1.1.1.1 dst 3.3.3.3. When reply comes from server, ACE will change src 3.3.3.3 back to 2.2.2.2 and forwards the request to client 1.1.1.1. SIMPLE LB.
Now comes a situation where let's say you want to hide the client IP from server or let's say server's default GW is not ACE or client and server are in same subnet but need to communicate through VIP on ACE etc.
Src 1.1.1.1 dst 2.2.2.2
After LB ace decides to send it to 3.3.3.3 but also policy multi match has nat rule (nat dynamic 1 vlan x). But packet would be forwarded from server vlan where you have NAT pool defined. So let's say pool IP is 3.3.3.4. So ACE will perform both destination as well as src NAT here before forwarding the packet to server and packet L3 header will look like:
src 3.3.3.4 ----->dst 3.3.3.3
Now when 3.3.3.3 has to send packet back, ACE will answer ARP for 3.3.3.3 and hence packet will come back to ACE which will again change the L3 header IP's and send it out the client VLAN towards client.
So NAT is always applied to server side vlan and that's why pool is chosen from server side subnet.
Let me know if you have any questions.

Kanwal

Ace 4710 active/standby SNMP config

We have 2 x Ace 4710 deployed in Active/Standby config. Since the configuration mode is disabled on the Standby unit, how can we configure the SNMP settings (such as location etc.) on the standby unit different from the active unit?
The 2 devices are in physically separated data centers so the SNMP location settings need to be set differently on both units. The standby unit does not allow any configuration.

Comments inline:
Since this is the admin context, we would better not do this. As i understand correctly, this will turn off the config sync on the 2 units and we may end up with some issues.
KM - Correct, you need to manually manage the configurations of both devices.
Also, if at a later stage, we sync the configs again in the admin context, it will overwrite the different config on the standby unit with that from the active unit?
KM - Correct, the device with the lower priority will be overwritten when config-sync is re-enabled. This is one of the reasons you need to be careful in the Admin context. For example: Ff the lower priority device has contexts defined that the primary does not, they would be removed when you re-enablethis command.
Since my requirement is just the SNMP location config, I do not think i should go for this; rather i can have some descriptive location setting identifying the 2 units in cluster mode...
KM - This would be more ideal than disabling config sync. You could also put both locations like this:
snmp-server location "San Jose, CA & Seattle, WA"

Hi Shiva,
plz guide i'm new with ACE LB, also find my n/w design for connected ace to server. but server accessing very very slow, but when i connect through my old server software LB (with two interface)then accessing very fast. I just replace my old serverLB(with two interface) to ACE4710 and connect the same scenario then why not server accessing smoothly with VIP .Reply soon only I connect ACE's two interface with switch.....

ACE 4710 Setup

Dear All,
I have task to add two servers to work with ACE 4710 , the client is coming from internal network and the end host (our servers).
I don,t know how to connect it physically and do the configuration.
Thanks a lot in advance .

Hi,
Below is basic configuration example with three real servers and Source NAT.
Let's say you have three servers:
rserver host SERVER_01
ip address 192.168.1.11
inservice
rserver host SERVER_02
ip address 192.168.1.12
inservice
rserver host SERVER_03
ip address 192.168.1.13
inservice
You add them in serverfarm
serverfarm host REAL_SERVERS
rserver SERVER_01
    inservice
rserver SERVER_02
    inservice
rserver SERVER_03
    inservice
After that you configure the VIP and condition. Here any means any protocol and port
class-map match-all VIP-30
2 match virtual-address 172.16.51.30 any
YOu define the L7 policy map
policy-map type loadbalance first-match SLB_LOGIC
class class-default
    serverfarm REAL_SERVERS--------->Serverfarm to which traffic would be loadbalanced.
policy-map multi-match CLIENT_VIPS---->L3 policy map.
class VIP-30
    loadbalance vip inservice
    loadbalance policy SLB_LOGIC
    nat dynamic 1 vlan 451----------------->You need to apply the NAT when your client is in same subnet as server so that return traffic comes back to ACE and not to client directly or when your servers default GW is not ACE.
interface vlan 251
description Client vlan------------------->VIP is in this subnet
ip address 172.16.51.11 255.255.255.0
access-group input ANYONE
service-policy input REMOTE_MGT
service-policy input CLIENT_VIPS
no shutdown
interface vlan 451--------------->Server side subnet
description Servers vlan
ip address 192.168.1.1 255.255.255.0
nat-pool 1 192.168.1.100 192.168.1.110 netmask 255.255.255.0 pat---->Nat pool defined. It should always be on server side vlan.
no shutdown
ip route 0.0.0.0 0.0.0.0 172.16.51.1
I would also suggest going through the below for basic troubleshooting and understanding.
