Inbound Connections Limit - Windows 7 And XP
Feb 24, 2012
I have an issue at my work where we are trying to added another computer to our network. We have 3 computers on XP (Included our server) and 7 on windows 7, 10 total.Now I've just tried adding the 11th PC and had no luck connecting to the server, but i do have internet access. I am aware Win7 allows 20 max connections, would we upgrade our server PC to Win7 and leave the other 2 computers on XP will I be able to add this 11th PC? Or do I have to upgrade all the remaining XP machines to win7 to get the result I'm looking for.

I have a 2621 router - old. but works well.Need to put in an ACL to limit the inbound SMTP traffic to be FROM a specific set of IP's, and deny all others.
I have tried various combinations with no luck. Something obvious, I am sure.
When I do a show access lists 160 it shows all SMTP traffic being snagged by the SMTP deny statement. All other traffic works correctly.
Here is my config so far...
Current configuration : 3093 bytes!version 12.2no service single-slot-reload-enableservice timestamps debug uptimeservice timestamps log uptimeno service password-encryption!hostname xxxxxxxxxx!logging rate-limit console 10 except errorsenable secret 5 xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx!ip subnet-
[Code] ....

RV082 - 1.3.2 I need to have RDP and pcAnywhere enabled to a customer site for remote support, but need to limit the incoming IP ranges to only our offices. I have the port forwarding set up and tested working. I then set up rules to deny all traffic on the needed ports and added rules to allow a few IP ranges from our office locations. I even tried a rule allowing all traffic from our main office but that also failed to allow RDP or pcAnywere connections.Now I can no longer connect from any of our remote offices. I followed the limited instructions that I found in another post but its not working.

ACE A2(3.4). Is it possible to set a rate-limit connections per sec from any source IP. For example, if a client is trying to GET a web page 10 time per sec I will send a reset or drop that connection.

I have a hub and spoke network with over 100 remote sites that connect to me via ipsec vpn. One of these locations, the only one using FIOS coincidently, is initiating 200+ tunnels back to my side which is causing saturation issues on my DS3. (I can post config if requested), and how can I limit the number of active tunnels it's establishing?

I'm trying to determine whether Cisco has any equivalent (in any platform) to some of the existing firewall rules within our iptables infrastructure. [code] What this does, is allow port forwards on port 3389/rdp. However, if a single IP opens too many connections within a timeframe, it starts dropping new ones.This is a critical requirements for certain security scenarios, such as preventing RDP brute forcing. A similar principle can be applied to 22/ssh.I've had a look around, rate limiting searches generally land me on QoS based discussions. I've seen people ask similar questions and get referred to CBAC. Whilst I can see similarly worded functions there such as limiting "half open" connections, I don't see anything there that limits the actual number of connection attempts you can make.

IOS Firewall (ZBF) Limit SMTP connections from same IP
we are running a Postfix MTA behind a IOS Firewall (ZBF) on a CISCO1921. Sometimes we get more than 2000 smtp login attemps like
postfix/smtpd[123456]: connect from (...) (...) postfix/smtpd[123456]: lost connection after AUTH from (...)
in one second. May be bruteforce or DoS ... nevertheless - we like to protect the Postfix MTA from this stuff.
Can we inspect the smtp and limit connections in a time period from the the same IP? Something like "not more than 10 smtp connections during 60 seconds from the same ip" .

I want to switch to a slower ISP because of financial constraints (specifically downgrade from cable to DSL), so I'd like to set up my Windows XP computer so that it downloads and uploads at the same speed that the slower ISP does. That way I can kind of "try before I buy" for a week or so, to get an idea if I can live with the slower speed before disconnecting from cable and incurring a disconnect charge. I was told that some software that limits your bandwidth also may cause distortion in video or audio streams, so I'd like to avoid that.

I want to limit the concurrent login my users can have. I have downloaded and installed Limit Login from Microsoft and followed the directions to a T. However, when users login it doesn't do anything. The scripts don't run (I have them listed in the logon and logoff scripts for users in the default domain policy). The scripts are stored in a share that everyone has read access to. What am I doing wrong? I have installed and uninstalled a million times following the MS directions included with the software to the letter, but it won't work. At one time I had it working and then we had some network problems with profiles and it got messed up in that process. Now I'm trying to get it back, but can't. Even uninstalling and reinstalling.

I have a dual boot computer - Vista Home Premium and Windows 7 Home Premium. When booted into Vista I can map my Network and connect to the Internet, a network printer (ethernet) and a second Windows XP computer. When I boot into Windows 7 I can still access the internet and my networked devices but I cannot map my network. Also, the network system icon (bottom right-hand screen) shows erroneously that no connections are available - but clearly they are! The attachments show the status of my Vista and Windows 7 connections. The only thing that appears to be odd is that my Windows 7 system is set to 'Public' and my Vist system is set to 'Home'. I have tried all manner of things to change Windows 7 to 'Home' but to no avail.

I had a Sony Viao with Windows Vista for some years and I managed to create a bridge using the Sony Viao laptop and my o2 usb modem. That was some time ago and now I have a new laptop with Windows 7 ?I have to mention that I do not have wireless connections. I have an o2 modem and an ethernet cable. They are the only two connections that show up in my internet connections. The LAN connection has an image of a ethernet cable connection while the o2 connection has an image of a phone.whenever I watch youtube walk throughs it never looks like my set up. Ive tried everything over and over. Turning off UAC, turning on sharing but nothing has worked yet. When I just select the LAN connection and right click there is an option to Bridge. When I right click the o2 connection its not there. When I select both the option isnt there either.

There was a big storm last night, and when I woke up I found that I couldn't connect to the internet. I have my computer plugged into the cable modem. The Windows network status says "Not connected, No connections are available". The onboard NIC that I had been using is no longer showing up in the device manager. I figured lightening might have knocked it out, even though my computer is behind a UPS and surge protector, so I bought a PCI ethernet card. This installed correctly and is showing up in the device manager, but I'm still getting the same error. When I unplug the ethernet cable, there is no change in the status.

I turned on my Netbook (Packard Bell NAV50, Windows 7) the other day and it would not connect to the internet. Not only won't it connect, but I can't even find any wireless networks, the icon in the bottom right just has a red cross. I'm currently using another laptop which can detect the network and next doors too so it is not a problem with the router. My PS3, phone, iPod etc also all connect fine. I've checked the fn f2 thing and that is definately on and working. Also when i click on "change adapter settings" in "network and sharing centre", it is there and is enabled and has the full green symbol icon but also has a red cross.

I would like to get either the Cisco VPN client to work or just to be able to connect with the Win 7 VPN connection. These are dynamic client IPs btw.I've made all the necessary accounts through the Web Management console but haven't had much luck so far. I did enable PPTP server and disabled "Block WAN Request" today to try again while remote later.
I think this is the v1 model. It has A00 on the back and I know of no other way to tell which version it is.
My other concerns is that the firmware is 1.3.98-tm and would like to update this to v2.0.2.01 . We have 2 remote VPN static IP users with existing connections that seem to be working fine (the admin that configed these is no longer here). I'm afraid to update the firmware in the event that this would cause some problem for them to reconnect. This article at the link below stated that a previous firmware ruined his connection and wouldn't allow him to revert back to the previous firmware. [URL]...
Is this true for all firmware upgrades for the RV082? Can you not restore to the previous firmware? If not, might it cause any configuration or reconnect problems for the existing VPN Tunnels if it works without other issues?Also, is the Cisco VPN client capable of connecting from WIndows 7 Home Premium?

I have recently bought an Samsung UE32ES5500 and I want to connect it to the internet. Not wanting to buy an expensive Samsung wireless adapter for the TV, I've decided to use an ethernet cable. Because the Internet cable passes through underground to the bedroom and the TV is located in the living room, i decided to put a router in the bedroom, and receive it's signal in the living room using a windows 7 laptop.Afterwards I connected the laptop to the TV through an ethernet cable, and bridged the two connections in Network Connections in Control Panel on the laptop. The TV successfully finds the laptop (and the router I think) but still cannot connect to the internet.

I have a Toshiba Tablet PC that came with the configfree software. It worked fine for a while but then it started giving connectivity problems. I tryed to disable Configfree by all means possible to no avail. Then I decided to uninstall it successfully, but I still can't return the network connections control to windows. It seems like it is still under configfree. My guess is that some internal switch at the registry level is still saying that the wireless control is not windows.

So I just installed Windows Server 2003 64 bit on an older HP Proliant DL360 G5 and am trying to connect it to my network but neither of the 2 NIC's are showing up under Network Connections... the only option I am given is the ''Add Network Places Wizard''.
I have an ethernet cable plugged into NIC 1 and the LED's work so I know it's not a bad NIC card- do I have to download drivers for the NIC? Do I download them to a USB/CD and then just boot from that?

I ve just finished setting up my first serial connections between two sites using Cisco 1800 routers. I can make connections from Site A to Site B using Windows XP clients, eg accessing exchange server 2007 running on Windows 2003x64, but the main problem is that when I try to configure Windows 7 clients to connect to exchange server on the other site, I can't make connections , no ping, no ssh , no http. What amuses me more is that I can connect to Windows 2008 servers using both Windows XP and 7.

I have two Windows 7 Ultimate computers and around 10 Windows XP (Home and Professional, SP2 and SP3) computers trying to connect to it. It's just a LAN (no internet access).I have set all of the password-protected sharing off on the Win 7 systems. I have tried opening up ALL of the permissions and such (since security is not really an issue).When I try to map the network drive, it won't let me merely connect to it. So, I have to click map network drive on the XP computer and hit "login with other credentials" and enter the username/pass for the user account on the Win 7 machine (we'll say Bob for user and Smith for password for the sake of example). It will mount the share (which is actually the C: root of the drive) just fine.
The only problem is the moment you restart the Windows XP system, it will lose the connection. My fix for it was to create a .bat file that contained the following: [code] I put it in the Progam FilesStartup folder to run upon boot. For the most part, it seems to work after a fashion. Some of the computers, though, will drop the connection to the two Windows 7 systems and need to be rebooted 1-2 times before they get it back again. Even clicking the .bat file manually will have the same result (you will have to reboot) if it drops the connection while you're using it. Plus, sometimes it doesn't map the drive correctly (I assume because the batch file is running before the connection has a chance to initialize on the LAN).I've also tried adding an "Everybody" user to the permissions on the Win 7 systems with full access, but it only seemed to cause problems with the existing connections.It might also be prudent to mention that both the Windows 7 and Windows XP systems are all 32 bit. I've also disabled the firewalls on the two Windows 7 systems. Neither of them have any antivirus or security software installed.

I have just moved homes and I am unable to connect wirelessly to the internet through the network in my new house. The computer is connected to the network with excellent signal strength but access shows as local only and will not connect to the internet.
All other computers have been able to connect to the internet with no problems, and my computer will connect to other wifi connections, no problem.I can connect with a wire directly to the router, but no luck with wifi. I have also had this problem with one previous wifi network. I have tried many things, including taking the compter to a computer shop for them to look at and having another professional look at it, but so far no luck.

We have a newly-purchased RVS4000 v2 with firmware v2.0.2.7. Its intended role is as a gateway between our local network of wired workstations and a Cisco 2800 series Integrated Services Router, which is at the receiving end of our T1 line. It is configured with static IPs on both the LAN and the WAN side. It does NOT serve DHCP for the LAN. Ever since I installed it, I have had repeated complaints from users of Vista and Win7 workstations that they lose internet connectivity about every 20 - 30 minutes or so. The only solution is to unplug the workstation's CAT5 cable, count to 30, and plug it back in. Then everything's hunky dory for another 20 - 30 minutes. Meanwhile, all our Windows XP and Linux workstations enjoy uninterrupted internet access. The router/gateway we replaced (a DLink DIR-130) never had this problem.

Firmware version : 3.0.0.1-tm (Jun 6 2008 20:17:06)LAN IP : 192.168.11.254 /24WAN1 IP : 192.168.1.253 /24WAN2 IP : 192.168.2.253 /24WAN3 IP : 192.168.3.253 /24MODE: Gateway.
Windows Messenger continually connects and disconnects. This behavior is permanent I only have problems with Messengers (all releases), web page access is correct. I check bandwith saturation and It's ok, I use less than 50% of each DSL. I configured the correct size of MTU for each DSL and the problem continues.Is there any way to set priority to this service? Is there any way to check if the "load balance mode" affect this kind of connections?

I'm trying to configure a L3 switch with some vlans. Despite we add a "ip default-gateway", that is displayed on the "show run", when we look "show ip route" there is no default gateway or gateway of last resource.On the show running we see the following:
interface vlan 31
ip address 10.221.31.177.255.255.255.0
!
interface vlan 32
ip address 10.221.36.125 255.255.255.240
interface vlan 36
ip address 10.221.36.105 255.255.255.248
ip default-gateway 10.221.36.105
One server connected to the vlan 32 is not able to ping the switch svi on vlan 36 (10.221.36.105).When we look the "show ip route" we see that the default gateway is not set.Ip routing is enabled on the switch. I tested the same configuration on my simultator and it works fine.I'm attaching the "show running", "show version", "show protocols" and "show ip routing".The ip routing is enabled on the switch!

My phone is a Nokia-N900, and I find the most useful way to interact with it from my PC is by ssh. Luckily it is possible to switch out the usb-networking module in the devices kernel to make it appear to windows as a generic RNDIS gadget. Plugging it into a windows PC I can now ssh into it, I can open an sftp session, everything works perfectly...
Except I can't access the web. I can't view other network resources. I look in the network connections section in the control panel and see my two connections, but I don't see any way to set which one to use for what. Seeing as I only use usb0 for ssh and eth0 for everything else, it seems I need a way to set it up so that usb0 only gets port 22 or something similar.
Is there any way to achieve this, or another method by which I could leave my phone connected to my Pc while using it for other network tasks?

Trying to install the Linksys AE1000 wireless adapter on Windows 7 x64. So I follow the instructions. insert CD. Insert adapter.The i get this error:
"Linksys Wireless-N Router requires that wireless connections are to be managed by the Microsoft Windows Wireless Connection Manager. Some laptops and computers are pre-loaded with a different wireless connection manager which prevents your Valet or Linksys Wireless-N Router installation from loading. If this is the case, then you will need to disable or turn OFF the other wireless connection manager, and enable the Microsoft Windows Wireless Connection Manager instead."
What manager? This is windows 7, I'm not using any third party wireless utility so I don't understand why I'm getting this particular error. If windows wireless connection manager is off, how do I enable it?I've always managed my network setting through the Network and sharing center,I've tried:
(1) sweeping registry files before install(2) Plugging in AE1000 first and manually installing drivers
When I did this, the device shows up successfully in device manager and the driver installs smoothly, however when I go to network adapters, the AE1000 is listed as disabled. I tried enabling it but to no avail. Running the network diagnostics claims the driver doesn't work despite the fact that it installed successfully.
After several restarts and disabling/re-installations I recieve the same error.The end goal is to connect the AE1000 to a Cisco E3000 router.
