We have had this issue for a long time in our enterprise. I don't work all the time in networking. I did a CCNA a while ago. We used to have a network manager who set everything up but he left the company. Basically we have this issue that if you connect to Cisco L2TP Remote Access VPN you can't access any resources at our Data Center. Also if you connect directly to the LAN.
View 10 RepliesWe are in middle of deploying WiSM2s on our network, from a design point of view i am confused on where to position the WiSM2s. We have 2 DCs and from best practice architecture view WLC should not be placed on the Data Center segment, but it seems that is the only option i have.
DCs host 6509s, i am planning to host 1 WiSM in each DC, all clients will be on seperate subnet. Do you foresee any issues with this deployment or any security issues? authentications are followed as per cisco recommendation, clients authenticated against AD through ACS so it is fairly secure.
How to trace firewall and load balancers placed in data center.
View 6 Replies View RelatedWe are planning to purchase an ASA 5505 for a VPN solution for one of our offices. The office has 50-60 user at peak load who would be connecting over the S2S VPN to the datacenter.
From a hardware standpoint, can the ASA 5505 handle this load. The licence is for unlimitedf inside hosts but what is the actual limit on this platform?
I have some doubts about the best solution for the design of a mini data center.In the data center there is a 6500 with FWSM module installed, there are some vlans created, all of them in the fwsm module. For example, a back end server to communicate with a server in the front end must always pass through the firewall. My question is, all these flows passing in the firewall does not degrade the speed of communication?What is the best practice, just pass the communications with the WAN in the firewall, and the vlan communication between front end and back end is only set up in 6500?

View 6 Replies View RelatedWe will be moving to a new data center in the very near future and with them our WAN IP addresses will be changing. Any best course of action for changing the IP addresses throughout the firewall configuration? Would it be possible/suggested to export the running-config, make the neccessary changes, then import the config? I am familiar with the ASA 5510 only so far as changes are required. It is not something I work with on a regular basis.

I have a pair of Cisco ASA's 5540, one of which I need to move to backup data center ( BDC), Presently I have ADSL router at disaster serve room with static public IP from ISP.
Currently, I am publishing all my internal resources through ASA. Now my questions, if I move Standby ASA to Disaster Server Room. How I can publish the same internal resources through standby ASA and make it standby as active during the down time of main server room
What are the list require for setting up Data Center for either University or Government?

View 1 Replies View RelatedI have a problem to solve in our data center, see attached drawing. HW: Our core switches consists of two stacked C3750 with ip routing. What I want to do is probably simple but I haven't been able to figure out the best method.
VLAN10 and VLAN20 should not be able to communicate with each other. (ACLs?)VLAN10 will have it's own default route/firewall. Both VLAN10 and VLAN20 should be able to send server backups to server in VLAN30. All 3 V LANs come in on a trunk from a pair of stacked C2960-S. I need it to be able to scale if we have 50 VLANs for instance, hopefully without long complicated ACLs. I've been considering VRF's, PBR but can't decide what's the simplest solution to this problem. I have never done this before so I would prefer to start off on the right foot.
Set up a Smart Wi-Fi yesterday. Linksys Smart Wi-Fi Router N600. Have 2 computers side by side. Connected my computer seamlessly. Works perfect. Went to set up my husbands computer (both computer are desk top HP Pavillion running windows 7) and the way I was doing it thru the network sharing center on his computer I was not able to get the computer to see the wi-fi. I tried both the router p/w and the p/w that was supplied by the smart wi-fi help center. So I wired it directly to the Linksys router with a new cat-5 ethernet cable. VOILA..internet connection! Question..is his computer secure even tho it doesn't have it's own p/w and is wired directly to the router? My thought is "yes" since the router is p/w protected.

My netbook works very well in my home network but when I brought it to my workplace, I was unable to connect to the internet eventhough I could connect to the wireless network. Other computers and laptops were able to connect and use the internet well using the same router. I tried manually configuring my IP and default gateway based on what I read but nothing worked.

I can't remember the last time I connected to the Windows media center on my Xbox 360 but I know recently I have tried to run a game server on the PC that the media center runs on. I was trying to do this by setting up a static IP. Here is the thread I posted to ask questions about it. I also used Hamachi to do the same thing. It basicly creates another netowork for you to connect to other people on, I guess. When I started using it another network appeared in my network and sharing center.I have tried reseting my modem and router. I've checked my network settings on my PC and my Xbox 360 and they both look like they use to look before I tried to use my PC as a server.

View 1 Replies View RelatedWe have an aironet 1130ag in a remote office connected to the data centre over MPLS. The Radius server is based on server 2003.We have hundreds of these points set up exactly the same but this is the only one giving me issues, I even stripped the config and rebuilt it and then swapped with a new access point
The issue is that clients can't authenticate when connecting to the access point but provides nothing in event viewer. Checking the RADIUs server provides nothing either.The access point error logs just state station: authentication failed
On looking deeper into the problem I enabled RADIUS debugging on the access point and got some interesting results, in particular is the line:
no sg in radius-timers: ctx 0x12EF0A4 sg 0x0000.I can't find out what no SG in Radius-timers actually means, but after that line appears I just see more retransmits and no sg fails.
I inspected the packets on the RADIUs server and found lots access requests coming from my access point and lots of access-challenges returning back from my RADIUS server - I'm not sure how often that's supposed to happen or if it's a one time occurance. I did however see directly after the first access-request that the RADIUS server returns with UDP and is fragmented, length is 1514...... could this be the problem? If so why cannot it hanlde fragmented packets?
I've got clients using the Cisco VPN Client (version 5.0.07.0290), and an ASA 5520 set up as the endpoint. 99% of the time this works great, so I'm pretty confident with the config, but there is one specific user who is having a problem (although sometimes it works ok for him). This user is connecting to the internet through a 3G dongle, and then trying to VPN in. I can see the connection being established, RADIUS authenticating his credentials, and the tunnel being set up without issue.
No data seems to pass through the tunnel however. Lots of packets are sent, but none are ever received back. Looking at the VPN statistics on the client, I can see that Transparent Tunneling is inactive, so I'm presuming I've got a NAT issue somewhere. The output of sh vpn-sessiondb remote seems to confirm this (user 1 is the problem user, user 2 works fine):

I have a TD-W8951ND v5 on the latest firmware.
I recently broke my broadband data cap which surprised me as I had not been using the internet much.
I only have tablet which I switched off having first checked the router to make sure there were no other wireless connections and adding MAC address filtering to be sure no one else was stealing my bandwidth. With just my router connected to the ISP, my ISP has recorded 170MB of downloaded data in 3.5 hours. Switching off the router stops the traffic being recorded (as you would expect), but when switched back on the large data transfers start up again.
I have plugged in an older router (not wireless) and no traffic is generated, so it seems to be the TP-Link router rather than my ISP or ADSL circuit that is at fault.
We have ACE module intergrated in cisco 6509 switch. We have performance issue for specific url while accessing through ACE, but it works normal when works with direct url.The users are getting error at middle of works , " applications are unable to get data ". We have configured http-cookie sticky like below, [code]
We are using two rserver in serverfarm and enabled port-80 services.
I did nothing different to my computer. It was online fine and then an hour later when I came back, it wouldn't load any pages. I have a DSL modem and a wireless router that also connects another family member's desktop to the Internet. (As well as our phones via wifi.). The connection is fine on the other PC through a wireless adapter (both are desktops), and on the wifi the phones work perfectly so I know the modem and router aren't the problem. But even though my desktop says it's connected (not wirelessly, it directly connects to the router.), no pages will load. If I use chrome browser it eventually tells me this webpage is not available regardless of which page I try to load, or sometimes it's telling me no data received - unable to load the webpage because the server sent no data. Yet oddly a couple of times after forever it seemed to half load a couple pages. Internet Explorer just keeps trying to load pages forever with blank white page as a result.

Got an problem with LMS 3.2/Solaris.
See no devices both in DCR and RME, besides, in RME device counters (Normal/Pending/etc) are equal to current device count, but then you try to select them for any operation, you unsucceed - 0 device selected, no list of devices, unable to export, no ability to do anything.
Upgraded to 3.2 SP1, no change. Spend a lot of time digging through logs at /usr/adm/CSCOpx/logs, find no problems at all. Seems, that some database parts were corrupted.
I decided to reinstall LMS from the scratch, but to do so I need to export the DCR device data and credentials.
Database is alive (dbaccess.pl install going smoothly, then connection with user lmsdatafeed works and allows to connect and select data from any SQL tool), but this view is not enough for getting from the DCR both device data and credentials.
I have the DB password I set up during installation.
Is there any way to get data I need connecting to LMS database directly with some kind of sysdba SQL database user?
