Cisco Application :: 2676 / ACE - Can't Reach Virtual Server
Nov 25, 2012
I'm trying to set up a load balancer within an OVH (hoster) infrastrcture, I've followed their instructions [URL] I'm using a RIPE block (5.135.193.xxx/28) and would like the first 8(5.135.193.xxx/29) to be used as the virtual server.vlan 2676 is the local one, and vlan 1227 is the public one.After all the config steps, none of these IPs are responding to a ping, nor a direct http request.
the full configuration is :
=============================================
ssh maxsessions 1
access-list ANY line 8 extended permit icmp any any
access-list ANY line 16 extended permit ip any any
probe tcp PROBE_TCP
passdetect interval 30
[code]....

I have a question regarding CSS loadbalancer. Let's say there are 2 vlans in CSS:
1. Vlan 10: 10.1.1.0/24 as external interface, interface where most of the clients are coming from.
2. Vlan 20: 10.1.2.0/24 for real server vlan.
Virtual IP 10.1.1.10 is created in CSS on behalf of two real servers (10.1.2.11 & .12) in Vlan 20. Client from Vlan 10 can http access to 10.1.1.10 successfully.
In Vlan 20 there's also few clients which need to access servers via virtual IP. Vlan 20 Client PC (10.1.2.101) can ping 10.1.1.10, but can't access 10.1.1.10 http service.
Is there any way for CSS to forward service request coming from Server vlan to be send back to the same segment?

do you know what happens if you reach the limit of, for instance 100 Mbps, compression. I know that if you reach the bandwidth limit ACE will drop packets but if you configure compression what happens if you have 110 Mbps.
I supossed that ACE will compress 100 Mbps and leave 10 Mbps without compression but I don't find this information anywhere.

We have an ANM Virtual Appliance, version 5.2, were we login and can go no further. This was working for fine for approximately two and half weeks. We created a backup and re-loaded the system via CLI with the same result. We logged in again via SSH and we have noted the following:
cscoanmsa/admin# sh disk
temp. space 4% used (141244 of 4951688)
disk: 7% used (353916 of 5935604)
Internal filesystems:
warning - /var is 100% used (89219000 of 89258112)
cscoanmsa/admin# sh application status ANM
[code]....
Is there any way to access and clean out the /var directory from the CLI. is this achieved simply via the "delete" command with the full path ?

I am completely new to the Cisco ACE devices but have been asked to look at deploying them. I have read the ACE virtual partioning paper which covers the ACE module, and it mentions the following;"In an active/active high-availability design, both the primary and backup Cisco ACE modules are active simultaneously. The active virtual partitions are distributed across both modules, such that approximately half are active on the primary module and the remaining are active on the backup module."does the same resilience model work the same using the Cisco 4710 appliances? I.e. can we split virtual partions across two physical devices thereby having an active/active scenario.

The upgrade process for ANM virtual appliance 4.2 involves doing a backup and restore as root user. I have looked through the documentation and have even reinstalled the virtual appliance to see if the install script gives away the root password for the OS but without luck.
How to set/find the root password?

We have a Comcast business class cable modem with a static IP address. There are two devices hardwired to it; a server and a Linksys WRT610N, The server is hardwired to it with port forwarding set for ports 21, 80 and 5900. It works perfectly and can be reached as intended by the outside world but not by our own network. Our Linksys WRT610N is hardwired to the modem. All computers on the wireless network see each other and can access the internet perfectly. So all seems well enough. BUT, no computer on our network can reach our server. Using the domain name or VNC connections from inside our system results in time outs and no connection.

Sometime in the past month my virtual server has been serving slow speeds to a majority of places when I used to get 500KB/s + speeds down and 250KB/s speeds up regularly. My home network is Verizon Fios 15/5 and speedtest.net reports exactly those speeds at any test server I choose.
I've been going back and forth with my virtual server host (1and1) about my virtual server download and upload speeds. I've done a lot of testing to see if there is packet loss with WinMRT and also traceroutes from a couple locations.1and1 has done testing and verified it's NOT their network causing the slow downs as their download tests have returned fast speeds. I've tested at about 8 locations to download this file ( [URL] I can assure you that link is safe, it's just a zip of the .Net 4 redist pacakge) and 6 out of the 7 get speeds ranging from 10kb/s-50kb/s, only 1 out of the 7 gets 400kb/s+ download speeds and that is located in Chicago, 4 are from Los Angeles area and 2 from Denver area and one from Orlando area.
Is it possible to get some users (Preferably West Coast USA) here to download and report the speed it downloads, location they are at, and the internet provider and package they have? If I cannot find the cause of this, I may have to move to a different virtual server provider which takes a lot of configuration for my server because of the nature of it

We have an ACE Appliance in a DMZ and the ACE Appliance's Admin Context IP is translated between ACE and ANM. The ANM Server does not get translated. It is just the opposite then in another Community discussion.
Our Problem: When adding the ACE4710 Appliance to the ANM imported Device List, we use the ACE's NATed Admin Context IP. Import works well, but ANM reflects the Admin Context IP with it's real configured IP. Polling the ACE Appliance does not work therefore.
Is there a possibility of telling the ANM, that the ACE has to be polled through a NATed IP? I could not find a field to set a NATed Mgmt IP.
Configured IP on ACE Admin Context: 192.168.0.10
NATed ACE Admin Context IP: 172.16.0.10
Imported ACE with IP 172.16.0.10 into ANM, but ANM polls for Rserver, Vserver, Probes, etc. via 192.168.0.10 - which is not reachable from the ANM.

I have an DLINK-dir 815 router.. I have tried for 10 hours to get broadcast IP to work, no luck.. All html/javascript modifications = no luck..The WOL works on LAN, but not over internet, so I figure it's the broadcast IP that needs to be virtual servered?

I wonder what the difference is between the virtual server and the port forwarding because the router I was using previously had only port forwarding. When should I use virtual server instead of port forwarding?

I have DIR-601 wireless router with two computers connected: Server (192.168.1.2) and Client (192.168.1.3 on Ethernet Port and 192.168.1.4 on Wireless)
I also use dlinkddns.com and my router's public IP is mapped as abc.dlinkddns.com.
In the router Virtual Server section, it is configured as:
Public Port: 3389 (for Remote Desktop)
Private Port: 3389
IP Address: 192.168.1.2 (server's IP)
I am expecting this to allow the client to access the server via windows Remote Desktop.
The current situation is:
- When wireless is on, the client can access the server's Remote Desktop
- When wireless is off and client is connected by wired Ethernet, the client cannot connect to the server's remote desktop. After timeout, the error msg is "Remote Desktop can't connect to the remote computer for one of these reasons: ...".
- When the client is in another network, it can connect to the server through the Internet.
I am sure it's not the client's problem because it can access via wireless or remotely from another network. It's not the router's virtual server config problem for the same reasons. Will it be a bug in the router? (hardware version: B1, firmware version: 2.00NA).

I put multiple rservers in multiple server farms?
So for example rserver1 and rserver2 are put in serverfarm production1 and are in use with particular sticky and load balancing settings.
Can I then create serverfarm test_production and put both rserver1 and rserver2 in it? Then play around with the sticky and load balancing settings as a test without affecting the production serverfarm.

I'm trying to design a CSS configuration that allows servers in the same vlan to be the source and destination of load-balanced traffic. My thought is to add two new vlans, one for the VIPs and one for the servers, then NAT the source IPs going from the LB to the servers.
Is this the right way to do it?I've never NATted using CSSs, so I wanted to verify what I'm thinking.Our current config trunks the vlans -
interface 1/1
trunk
vlan 1
default-vlan
vlan 555

I've got a DIR-825 RevB Firmware V2.06NA on a static IP wan connection routing to a SBS2008 server and 10PC's. The server is serving mail, web, and files. Router has virtual servers setup for http, https, smtp, imap, imapssl, smtpssl, pptp, remote desktop, and a few others.
Everything works fine, but the routers https forwarding stops running periodically about half an hour after reboot. The server's working fine, but it doesn't see the https request, it looks like the router is trying to serve the 443 request itself. After a router reboot everything is back to normal.
I've replaced the router with another dir-825 and it has the same issue.

Am running firmware ver 1.00.19. Set up DDNS with DynDns.Org and all is well. Set up virtual server with DDNS info. Trying to connect to an IPcam (Foscam 8905W). IPcam is set up with static IP with ip outside Belkins DHCP range.
Problem: When trying to access the IPcam through the internet (DynDns) Belkin takes me right to the Belkin router Setup screen, not to the virtual server settings (IPcam). I was able to do it a couple of months ago,but not now. I may have upgraded my firmware in that time from 1.00.12.

Why is loop-back only working on ports forwarded in the Virtual Server section and not Port Forwarding or even DMZ? I have seen a post about loop-back on the DIR-655 from a while ago that had said to disable SPI and change NAT Endpoint to independent, I have done this and loop-back still doesn't work.

If we use an ACE4710 to load balance two real servers, obviously it will use health checks to determine if a server is down.When it detects a server is down, it will not send it any more traffic.But can we also have it take any other action? For example maybe email an admin, or send an SNMP trap? Or better yet, can we use a custom TCL script to do other things, like launch some custom activities?

I had a working server running ISE version 1.1.0.665 but someone in the build room decided to pull the power out of the server rather than shutting it down correctly. I have booted the server back up however the web management page was not accessable. I have checked the server status and the end result is the Application Server in the "still initializing" stage. I have left the server for several hours and the status has not changed.
I know people have previously run into this issue but no one has posted any resolution or confirmed that a rebuild is the only solution. I have tried to create an on-demand backup but it seems to fail when attempting to provide the credentials (which are correct) for the FTP server.

I have a Cisco ACE 4710 A5(1.2). Scenario: Inbound call from PSTN to SIP Phone. Call comes into the VIP and then load balances to sip server, the server then routes the call out via WAN to the SIP phone as below:
PSTN SIP Providor >(router)> ACE4710 > sip_server(s) > ACE4710 > (router) >SIP Phone
Note: Router is Cisco 3925 with "ip nat service sip udp port 5060" and Port 5060 mapped to the VIP of the ACE.If I put the sip server directly behind the router it works fine. From behind the ACE:
If I turn on sip inspect on the VIP the call setup (INVITE) and termination (BYE) work fine but the audio loops on the PSTN side from the mic to the speaker.If I turn OFF sip inspect then the audio is fine and mapped correctly but the call terminaton (SIP BYE) hits the VIP from the PSTN but never reaches the sip server.For ease and dianostics, I have turned off all sip servers except one meaning the load-balancer has only one server to choose from.SIP Call_id sticky is setup and seems to work, though irrelevent with one server only on test.How do I get the ACE to accept 'server initiated traffic' with sip inspect so it knows about the pending BYE when it comes back from the IP phone via the VIP?Config below, image attached. Bridged mode (also get the same result in routed mode)
access-list everyone line 8 extended permit ip any anyaccess-list everyone line 16 extended permit icmp any any
probe sip udp 1 description SIP Health Monitor interval 30 expect status 200 200
