We once had a virtual server with two network adapters, one was internal and the other was external, and people could access it directly from the internet.
That server recently, died (someone put the .VHD file on a massive RAID 0 array, and that went boom), and I need to set it back up again. All the DNS entries appear to still be there, but how to assign the external IP to the network adapter. I tried Google, but my Google-fu must be weak today as I can't find anything useful.
It's a Server 2008 R2 machine running inside Hyper-V. Nothing's changed except for the new Windows install, it's running with the exact same VM settings, which I didn't touch except to add a new VHD.
Whats the difference between DNS Server and External IP Address? When I dump Ipconfig /all into a .txt file I see that it shows three seperate values for the DNS Server. My question is, since ipconfig /all does not give an external IP address, are they the same? Why are theyre three?
I am desperate to make some kind of translation which convert an outside IP Address of our web server to its inside ip address so that requests can be routed internally to the server.
This is what we have: A wireless network with an SSID to serve visitors. We also have an in-house web server which can be accessed internally and externally. We have a ASA 5520 that protects the internal network, including the Web server, and also routes all traffic from the all visitors connected to the public SSID to the outside. The DHCP server for the wireless network for visitors is configured to give the 8.8.8.8 as dns server. The problem with that is that the www.ourwebserver.com is resolved by Google's dns server to the public IP Address of our web server! The traffic then is sent to the outside interface of the ASA 5520. The visitor who wants to access our web server cannot connect!
How can I configure the ASA to route that traffic to our web server with the public ip address to the inside ip address of the web server?
I am trying to give an static ip address to a time clock on my network and for some reason when I connect time clock to network it will always get an ip address from a different network. for example my computer IP address is 192.168.2.70 when connected to network, my default gateway is 192.168.2.1, the IP address that the time clock always gets is 192.168.1.120, there is no way to tell the time clock what IP address I wanted to be it has to get it from router (that is what the manufacturer told me), router (16portLiksys) does not have DHCP enabled the guy who set up network left it disabled, on his notes he says server (dell server T110) is acting as router is that true that a server can be acting as router?what do guys think is going on here?all the computers hooked up to network have static IP address.I also notice that when I connect a computer to router it will get an IP address from different network the same as time clock.I tried to reserve ip address on router by entering MAC address from time clock but it won't work. I am not very familiar with the server settings I have not try changing settings on server, I am not even sure the guy who set up network is right about using server as router.
HP wifi printers (I've had 2 over the last several years)eventually have a disconnect with my wifi router and was told (by an experienced IT guy from my last job) I should assign the printer a static address to eliminate the problem. How can I assign a static address to my printer. Here are the models Router: Belkin model F5D9231-4v1(01); Printer HP Officejet 6600. I know how to access the printer and manually enter an IP address and subnet and such, I just don't know which numbers to use where. I also know how to access my router, via typing in the IP address in Internet Explorer, but i'm unsure of which tab within the router's page (i.e. is it category wirelessunder MAC address control) or which numbers (IP address or MAC Address)and where should I get the correct numbers from (i.e. go run, cmd,IPconfig/all).
I am using Windows 2011 SBS and Windows 7 clients.My server has a DHCP range of 192.x.x.150 to 192.x.x.199 and all other I.P. addresses are static. On a workstation located at I.P. 192.x.x.13 I am seeing an address conflict.When I perform an "nbtstat -a 192.x.x.13" command from the server I am given the logical computer name of a staff members personal laptop.Investigation of the laptop reveals that it is set to DHCP, and clearly the address of 192.x.x.13 is outside of my servers DHCP scope, so this I.P.should never be assigned, let alone in duplicate.I Google this topic before posting, and it was suggested that IPv6 could be having an adverse affect. I determined this because I performed a ping on the laptop and only got a MAC address back rather than an I.P. address.However after unticking IPv6, and rebooting, the laptop is still causing havoc.I can set a static I.P. address on the laptop, however this is not ideal.
I just got a brand new laptop and I can't get it to connect to LAN.It's plugged in to the same hub as my main machine and I can't even access my router UI.It's not the cable because I tried plugging in my main machine's cable to the new laptop and the same thing happens.ipconfig reveals an Autoconfiguration IPv4 Address of: 169.254.197.187 But that number should say 192.168.1.1xx I've tried uninstalling and reinstalling the Ethernet driver as well.I've tried resetting the router and modem.I've tried resetting TCP/IP.
My company wants to create a VPN Tunnel to allow a remote office to connect to ours. I purchased 2 ASA 5505 and I was expecting to be able to set this up without any issues. Sadly, that is not the case.
What I'm having trouble with is configuring my Public IP Address to the device. I go through the setup wizard and enter the IP Address like normal, but I have no option to input my ISP's subnet, Gateway or DNS. Without those, I get no internet connection. I know there is a way to do this, but I'm stumped.
My Specs:
2 ASA 5505 series ISP Modem (Which they control) - SMC SMCD3GN with DHCP disabled
hrome threw me a DNS lookup failed. I go into my network settings and I noticed that I had limited connectivity. It would switch between no network access and no internet access every few seconds. After a bit of fiddling around, I got it to connect through assigning myself a static IP. This isn't exactly convenient because I use this computer on multiple networks. When I try to have it on automatic IP, I get no IP address or default gateway when I do an ipconfig /all. It would appear that my router quit assigning my laptop an IP for no reason whatsoever. DHCP is enabled on the router, and all other devices work fine. What could possibly be the problem here? I'm 99% sure it's not an IP conflict either. It's not being MAC filtered because I'm on the thing right now posting this through a static IP. It's not my A/V because it's worked great in the past. Perhaps I should also mention it occasionally says "unidentified network" instead of the SSID
I'm fairly new to Cisco configuration and I am looking at a problem for a client that involves the use of a Cisco 887 (wired only) as the main router/gateway. The problem I am investigating involves the allocatoni of DHCP addresses from the device to a product we have designed that connects to the router. I am attempting to set the 880 up on the bench with no ADSL connection and just use the DHCP feature of the box for the 4 switch ports on the back. I have tried all kinds of configurations from default. Whatever I do I can't get the router to assign an IP address to anything that is plugged in (Windows or Linux machines). What could I be doing wrong ? It can't be that difficult to get the system to just act as a DHCP server.
The problem is WAP 610n not assigning IP address through DHCP; i have to add IP address mannualy.
just go through the details below: In my network environment we are using : CISCO Router 800 series; IP: 192.168.1.1 Domain server with DHCP server : 192.168.1.2 DHCP pool: 192.168.1.234 - 192.168.1.250 WAP IP : 192.168.1.236
WAP configuration : configuration view : mannual Wireless band : 2.4 Ghz Network mode : mixed channel width: 20 Mhz only standard channel : auto SSID broadcast : Disabled [ for security reason] Security mode : WPA2 Personal Encryption : TKIP/AES Firmware : 1.0.01 build 94, Oct 26, 2009 Note: In status menu it is not showing any default gateway.
Encapsulation method in CISCO router : PPPoA [ as instructed by ISP]
some problems when I was trying to install my X3000 as a DSL modem and router.I had to assign a designated IP address but I have dynamic IP from my internet supplier. I can't get pass the stepp of assigning IP address.
Is there anyway you can assign a static IP address within WAG160Nv2 to peripherals such as an XBOX?
The knowledge base only seems to show how to assign an IP address in the XBOX but when I have to reboot the router, I've noticed the XBOX is assigned a new IP address when viewed in the router pages.
If I set a permanent IP address in the XBOX, this will no longer match what is in the router.
Recently purchased 5 SGE2010P 48-port switches to replace older L2 switches. I have 4 switches in single stack and one as a standalone. Both the stack and standalone will connect to at least 1 Dell 2724 switch. Both the stack and the standalone Cisco are in Layer 3 mode.
I have created several VLans on the Cisco switches, and am trying to assign an IP address to the VLan, but cannot seem to figure out the web gui. Each time I try to use Systems > System Management > IP Addressing > IP Interface, then click Add, it simply changes the existing IP of the management interface. So, I'm not sure how to go about assigning an IP Address to an Vlan.
The DHCP/DNS server is on ip address 10.1.100.103 with an alt on .102 I'm attempting to integrate a 4510R+E into an existing network and use existing DHCP/DNS windows 2008 server to push out IP addresses to connected computers.
I want to assign a VLAN to every port for management purposes and then I put an IP helper address on every VLAN.
I've attached a the 4500E partial config. I'm attempting to get Gi1/44 to a state where I can plug a computer into it an resolve an ip address and gain internet access like all the devices on the existing network can do.
I've created a new scope in DHCP with the ip subnet of 10.60.211.0 255.255.255.0 It leases addresses from .1 to .253
The computer will not resolve ip addresses with this config.
I have an old ASA 5505, and I'm having some trouble with Nat Hairpinning. I've done this with other firewalls before and I am having no luck now. I have an internal address that I wish to forward from an external address- so if someone goes to 123.456.789.012:3456 then it will forward to 192.168.1.244:92 (All numbers are arbitrary here- only for illustration). I have and Access Rule and NAT and PAT set up so that I can get in if I originate from outside the LAN. What I am trying to do is to have this work from inside the LAN as well- so that if I am at my desk, and I connect a device and type in 123.456.789.012:3456, it will deliver the content at 192.168.1.244:92. The problem I am having is that it just isn't working, and I cannot figure out why- When I started here, there was an address configured to work this way, and it still works- I just cannot find what is different between what I am doing and what the person who configured it did.
We have several ASA 5510 firewalls which are being used as VPN gateways.RSA SecurID is the authentication mechanism using native SDI connectivity. No ACS server is being used.Is it possible to assign user Group and other attributes (such as ACL), using the SecurID RADIUS server? I know this is what the Cisco ACS is for, but is it possible using the RSA RADIUS server itself?
My IP adress has always been external. About 2 years ago, after reinstalling my windows,(I am using and used before reinstalling windows7) my IP adress started to work as it wouldn't be external. I couldn't host servers and stuff like that anymore.I tried turning off firewall, few other tricks but nothing changed.When I look information about my IP adress ,most of the sites see it as external.Also, when I call my interned providers, they tell me that they see my adress as external.
Some details :
-Internet is provided by a cable (not using telephone, TV or something else from those internet dealers)
-I am alone using this internet, no one else is connected to it.
I use an online software host. They put print jobs into a queue and send them directly to my printer. I just got a new printer. The software host needs it's "External IP address" I have my internal IP address. I pinged the printer and got my internal IP address instead of the printer's. I am on a home wired network running through a modem and router.
I have a client that has 2 servers behind the same router. They have an IP block from Time Warner -> (x.x.x.18-.30) The router has the IP address of x.x.x.18. Server A (192.168.1.6) is setup with the forwarding of ports 22, 23, and 115 and can be seen with the ip address x.x.x.18. An external company needs to access the other server and is requesting an external IP for Server B (192.168.1.5) which need the same ports open along with 6200.What is the best way to set this up with what they have? The router is a Linksys WRT54G. Is there a way to set them up with a x.x.x.19 address from time warner? Is this something time warner will need to do?
I have a home desktop, home laptop, and work laptop that I use. I have Ultra VNC setup on my work laptop that allows me to remote into that machine when I am traveling for work. I have always been able to use the external IP address (not private) to login into the machine with no problem. This week, for some reason, I can no longer do that. When I started doing some discovery, I noticed that when I have all 3 machines booted up at home that the exact same external IP address is assigned to all 3 machines. The internal IP addresses are all different as they should be.Shouldn't each machine have a seperate external IP address assigned as well? Or is this working the way it should? I didn't change any setting on my router or DSL model. But I think the conflict that VNC is having on my work laptop is that it has the exact same IP as the destination computer and it fails. I can remote in if I use the private IP address (192.168.x.x) just fine.
We have a strange issue for one of our customers that recently migrated to our internet service.They are trying to vpn to an external ip address not controlled by ourselves. The issue is only on one subnet and isolated to Mac’s, PCs in the same subnet also work fine. They were able to vpn from the MACs before they migrated to our INET solution. They previously used a checkpoint FW for their outside NAT and firewall and now are using a failover pair of asa 5510s. I have packet traced out the firewall and there should be nothing blocked. UDP ports 500 and 4500 are open to the destination ips from the correct subnets. All other subnets with Windows PCs can vpn out to external ip without issue. The users in that subnet with the MACs can also browse internet fine so the routing and nat overloading is also ok
When they try to initiate a connection from the macs i can see the connection/xlate coming in from a source port of udp 4500/500 and also a destination of udp 4500/500 instead of a random source port. Just this evening we managed to get one device connected but no others. Would the fact that the source port is claiming 500 and 4500 stop the other macs using the same source ports at the same time to connect out? They are using the onboard mac vpn client, he can’t get the Cisco one working at the minute. [code]
We have a Router with one External IP and a couple of VLANs. We have got a Teleconferencing Unit that needs almost every port known to man to work, so decided to get the unit its own External IP.
We have the IP now and how to get it in the router and then also to use it only for the Video unit (From outside straight through to Video).
Im comfortable adding lines to the router but just don't know what the lines should be.
The new IP's purchased are 116.199.222.200/30 (Only need to use one address, lets say 116.199.222.200). No idea what the subnet mask should be...
The router config below stripped of irrelevant stuff:
interface FastEthernet0 no ip address ! interface FastEthernet1
Our company uses a commercial copier monitoring package called FMAudit to obtain meter readings from our clients' copiers, and it uses a feed to send the readings back to us. We have used port 90 for this purpose.Due to a recent server crash and emergency reconfiguration of our network, we have moved our FMAudit central server from in-house to a hosted service, with of course a different external IP address.
Without interfering with our other systems, is there a way to redirect JUST PORT 90 to another IP address external to our own? I don't care if it has to happen at the router or server level. We are using Server 2003 and a Cisco 887VAW.
The problem is that the PABX is sending out an internal address in it's INVITE messages and the ASA5505 isn't changing the internal address to the external address.We need> From: Calling Number <SIP: SIP Username@Public IP Address>However our PABX sends out> From: Calling Number <SIP: SIP Username@Private IP Address>. How to translate the internal IP address to the external IP address on an ASA 5505?
I have a EA3500 wireless router with the new style (smartwifi) firmware. I've scoured the web admin interface and can't find any sort of 'status' page that would tell me the external IP. I've looked through the support docs but they only show how to find internal/local IP.
Alright so I have an SSH server running on my network. I can successfully connect to it from a local computer using the server's internal IP address, AND I can connect to it from a remote computer using the server's external IP address (it's properly port forwarded).
However, when I try to connect to the server from a local computer using it's external IP address, I get a connection refused error. Is there something I'm missing?
I have a mail server, with external access which works fine for external access thorugh our router (a 1941). I have a laptop which connects to a wireless network that is inside our router. When attempting to navigate to the webmail or use outlook, it cannot connect.
The laptop is configured to access the mail through the external path as it would be offsite occasionally.
I think the problem seems to be that the traffic is not leaving the router to come back internally. The laptop can ping the external address ok.
I read about something called hairpinning - is this what i need to be looking at?
I have a WAG160Nv2 and I want to block specific external ip addresses from trying to get at our server that uses the WAG160Nv2 as an internet gateway. It's not immediately obvious if this can be done from looking through the config pages.
We have an ASA 5505 and are changing ISPs so we'll be getting a new static IP address. How do I change the external IP address using ASDM? (I haven't done it in 5 years so I'm rusty and just want ot make sure.) The ASA and ASDM are up to date.Am i correct in that I only need to change the external address in the configuration under Interfaces, then under Routing - Static Routes - Gateway IP I just need to enter the new WAN gateway address?
