Keeping Internal IP Addresses The Same?
Jan 23, 2012
I have multiple devices running on my home network. Every once in a while my wireless router starts playing up and I have to reset it.Whenever this happens, it changes the internal IP addresses of the devices. Is there a way to make the router keep the same internal ip address for each device? ie Laptop stays at 192.168.1.8I have a few forwarded ports for remote access to certain pieces of software, so each time the address changes, I have to go in and change these details, which is quite frustrating.

Have a WLC 5508 running 6.x code with LAP's providing wireless for our internal laptops (WPA2 and EAP-TLS). I want to provide guest wireless which goes out a different port on the WLC to a guest firewall/cable modem. However, we want to prevent our internal laptops from being able to use the guest wireless. I have RADIUS (IAS) and LDAP for my AD available. We would prefer not to have use Lobby Ambassador and just have the guests use a simple password or web passthru. Guests may be laptops or smartphones. What options are available? I have tried a test setup using dynamic vlan assignments from RADIUS using the IETF flags, but can't seem to get it to work. Is there a way to identify the SSID is being used at the RADIUS server?

Is it possible to have more public addresses to more internal addressees? I have an internet provider which is in control of my router and he is telling me it is not possible. It's a Cisco router and I have static IP address.

I recently cut over from a WRT54G to a RV120W. I am having an issue where I type [URL] (for a server running on my network) in my web browser while on the internal network and it always comes back with the router login page. Basically it is supposed to go out of the router and then come back in on the public IP address and hit that server. There was a function on the WRT54G called "Filter Internet NAT redirection" which when turned off would allow this to happen. I am not seeing a feature like this on the RV120W

ASA 5505 Firmware 8.3(4), ADSM 6.4(2).I have a public IP address of 168.87.3.4.I need to forward ports (5060, 5080, etc.) to one internal address. (192168.1.1).I need to foward different ports (10020-10080) to a different internal address (192.168.1.2) Everything I read tells me how to do this in a 1 to 1 static NAT.

We recently purchased an SRP527W router because of its capability to configure site-site VPN tunnels. The configuration of IKE and IPSEC is working and the tunnel comes up but the problem is that the router is passing our internal IP addresses through the tunnel. The remote end we are connecting to requires us to hide all traffic behind one IP address which would ideally be our external static IP address from our ISP.

I run a minecraft server over an ad hoc network, but every time we start the server up again, we have to find the new IP address, edit the server files, and re-enter the new IP address onto all the computers.Is there a way to make it so an Ad Hoc always boots with the same Ip Address?

In setup for old RV042 (V1), when updating / adding Mac addresses, the table is always sorted by IP addresses. But in the new oneRV042 (V3) I have, even with latest firmware 4.2.1.02 the list is random, thereby increasing the chance of user entering DUPLICATE IP addr with diff Mac addr. That will result in conflict.If the firmware sorts the DHCP entries by ip addresses, user would be able to catch duplicate ip errors even if the system does not flag the errors. All Cisco smart engineers can you all get the dhcp entries SORT by ip addresses.

I have a wireless repeater (NETGEAR Universal Wifi Range Extender WN2000RPT) thats been giving me issues lately when attempting to use it to connect an xbox 360 I have to xbox live. The Xbox and the repeater are connected by an ethernet cable so there is no wireless connection going on between them. My router (Cisco WRVS4400N Wireless-N Gigabit Security Router with VPN) located in the basement of my house, and the extender is on the second floor of my house. The xbox that I want to connect to the internet is located on this second floor and because of the distance between it and my router a normal xbox wireless networking adapter doesn't seem to be working.Anyway, if I plug in the extender and let it get a connection, and use it right away to connect, i have no issues. The connection will also usually remain working for a while after I first get it working. The problem comes after I'm done using the xbox and i shut off the console and the tv. When I come back to the xbox later and turn it on, the networking extender still shows it has a full connection and is working properly on the outside with the green lights, but the xbox will not connect and it will tell me the extender is not assigning an IP automatically (DHCP turned off), when I know for a fact it is turned on. It is almost like the extender freezes after I leave it alone and on for a while. When this happens I usually unplug it and let it connect, and everything works as it should again. After a while its gotten a little annoying having to do this every time I need connection.

Keep a log of my own (Wan) IP-adress. It should look up my own IP-address and write it away to a log, so that I can look up a few weeks or months later what my IP-adress was on a certain day. I am using a router at home.

I would like to know if it is possible to add a second router to my home network.
My son wants to use his Nintendo DS online but the device does not have WEP capability, it can only deal with the less secure WPA option.
I am not willing to drop my preferred WEP just to facilitate one device, but I do have a spare router and I am wondering if it were possible to hook the second router up and allow him to connect using WPA?

I have two dir655 routers that are connected. The second router is not setup as a wireless access point, but I am open to that if it will work. The second one is going to serve as a public wifi in a business, with a separate SSID. The first one is going to handle the local business network, with its NAS and printers. How would I prevent the public wifi from accessing the first router?
I have tried the guest wifi partition setting, however it still allows access to the lan devices on the first router. It does partition with the second router properly though, but thats not worth anything to me cause there are no lan devices on the 2nd router.
Would it work right if I turn the 2nd router into a access point, disable the dhcp server, and set it up with the guest wifi partition?

As part of my course, I have to install a brand new network, including cabling, setting up equipment etc in a room whilst ensuring that the current network system for that room is still running without any issue. How to do this as it includes taking out/changing the infrastructure in relation to cabling?

I am installing a network that has two SG500X-24 switches as core and several SG300-52 switches as access switches. I've seen in the SG500X-24 datasheet that there is a True Stacking feature. But in the data sheet there are not a lot of details about it. My doubt is the following. If I configure the two SG500X-24 switches as a single switch through stacking them, can I connect one SG300-52 switch to these two SG500X-24 switches through two cables (both configured as a LAG in the SG300-52 and in the SG500X-24 stack, one cable per SG500X-24), the the first cable connected to the first SG500X-24 switch and the second cable connected to the second SG500X-24 switch and keep both connections active?

it's across 3 floors and the current setup is a single wireless router DIR655 (1st floor), but the WiFi suffers greatly on the floor below/above.
I have sourced 3x D link switches and 2x more DIR655's and would like to have all machines/consoles/phones etc in the household on the same network. Is it possible to keep one DIR655 as the main wireless connection and have the other as pure AP's as well as keeping the same SSID?

I have been testing WiFi devices such as the iPhones and iPads connectivity with the following setup:
1. 3502i AP
2. WLC 5508 SW 7.0.98
3. NGS
The i-devices have iOS v4.2
My goal is to have the guest user i-devices maintain the credentials (username and password) when they login again to the wireless network. Like if the device sleep, I think definitely they would loose those IP address issued by the DHCP. Once the guest user uses them again and connect them to the wireless network the user would not need to type-in those credentials on the Web Authentication page directed by the WLC.
The credentials are issued by the sponsor who created them on the NGS. It seems that there are WiFi problems with these i-devices. But somehow, I'm looking for a solution that would automated the logins like a checkbox if you want to be kept signed in, on Yahoo or Stay signed in for GMail.

Having problems with my wireless router, dropping and keeping connection active. For some odd reason I keep dropping connection either wireless or wired. I have a total of 5 items going through this router. 2 of them are wireless and the other 3 are wired. The wireless items are a desktop computer that is using the Wireless USB adapter to get online. Sometimes it drops and most of the time it doesn’t have any problems. I have a laptop that sometimes the connection goes from strong all the way down to no connection at ALL. It starts at 54MBPS to down to the RED X over the wireless manager. Forgot to mention both of these machines are Windows XP. If I reboot the laptop, it comes up without any problems.
Sometimes I tell Windows XP to manage the Wireless connection and tell it to disconnect and re-connect again, it goes. Now for the wired items, I have 2 gaming systems and another computer plugged directly up to the router. For some odd reason when I double click on the internet, on the computer that is hooked directly to the router, it says page couldn’t be found. I know that there is connection and there is nothing running in the task tray except for the Anti-Virus and Firewall. The browsers that I am using are Internet Explorer 8 and Mozilla Firefox 3.0.10. Also checked on the back of the machine to see if I have link lights and everything is flashing. Finally, when I click the homepage or refresh button about 2 or 3 times, it goes through.
think that I am overloading this Router and it can’t handle it. I might have to look into sending "Keep Alive" packet setting on the router.

We have a Linksys E1200 modem and I have been having problems with keeping my son from using the wireless interenet. I did change the password and that worked for about 24 hours and then he was able to get onto it again. He has a nintendo dsi and he is smart enough to figure out how to dismantle any parental controls on his gaming device. I think that he resets the modem in order to get back onto the internet in order to use his gaming device. Someone told me that you can register each item individually in order to keep kids from using it but I have no idea as to how this works. We have two iphones, a lap top, and two tablets.

I have a Cisco 877W-K9 router, and I for the life of me can not work out how to enable multiple SSIDs on the AP whilst keeping them all to the same VLAN?
I know this may seem silly but basically for our clients we setup WPA-Enterprise for one SSID and WPA-PSK for the other to help ease migration between the two etc, however all I can seem to do at the moment is create multiple VLANs and use ip unnumbered vlan1 to sync them all into one, but this seems really silly.

Our company is a small one and steadily growing towards mid size. We currently have about 200 or so users. Naturally we have run out of IP addresses and now we must redesign the entire IP schema.Initially our plan was to just implement a class B subnet for the whole network with certain ranges belonging to certain kinds of devices/machines/servers.Are there any cons to this? If so, could you link me to documentation that explains this?

I have a DIR-615 rev C1 with the latest firmware (v3.13). I am trying to reserve all the IP addresses in my home network, which includes a printer, 3 computers, a network bridge to a PS3, the PS3 itself, an iPhone, and an A/V receiver. On my network setup page, I can see the MAC addresses under DHCP CLIENTS for the wired Win7 computer, a Win7 computer with a USB adapter, the PS3, the network bridge to the PS3, the iPhone.

I'm planning to setup a network with more than 300 PCs. I know that using class C address is not enough to allocate number of IP addresses required. What I meant in the preceding sentence is that If I use this network address 192.168.1.0 (class C), it will allow only 256-2 = 254 IP addresses, What about other PCs in the network ?

We got a bunch of port-sec violations on port fa1/0/42. after checking logs, we noticed that the MAC address responsible for generating the alert was not one, but many.We asked the user, he said he only restarted his computer.The MAC addresses happen to be existing MAC on the network.How is it possible that a port-sec violation is made by many MAC addresses on the same port, successively?

When I try connecting via anyconnect the logs (and anyconnect messages) state the connection "cannot be established due to no addresses being available for SVC connection'". The group etc has a dhcp scope assigned, (and this was working for the past year). I'm not sure what config changes (if any) he made before leaving.

Me and my girl friend both work from home doing freelance work using the internet. The company we do freelance work for allows one agent per ip address and checks the ip address for multiple agents I guess.I only have one modem, router, and two computers, but I believe they are on the same ip address.Is there a way to have two different ip addresses so we wouldn't have any issues with our work here?
