D-Link DIR-655 :: External IP Address Assignment?
Mar 3, 2011
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.

I couldn't find a section for the 651.
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 want to use RADIUS (of Secure ACS 5.3) to authenticate users within an ISP environment. Users log connect to a network using a point to point connection (L2) and then they are sending a RADIUS request to get IP adresses. Secure ACS is not quite easy to look through in that case.

I've got a network of several AIR-LAP-1242G LWAPP access points controlled by a 2112 WLC. I assign static IP addresses to each LWAPP, but every few weeks, a couple of them (at random) revert back to grabbing a DHCP-assigned dynamic address for themselves, despite the fact that they're supposedly solidy configured to have static IPs. What's going on here? Is this a bug in their firmware or the WLC's firmware? If I reboot the APs, then they come up with their static IPs, but after running some random number of days/weeks, will spontaneously change their own management IP addresses and grab a DHCP address for themselves.
The 1242G APs version numbers reported by the WLC's web GUI are:
"Software version" 5.2.193.0
"Boot version" 12.4.13.0
"IOS version" 12.4(18a)JA2
"Mini IOS version" 3.0.51.0
The 2112 WLC is running software version 5.2.193.0

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.

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.

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?

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.

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?

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
[Code]......

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.

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.

Accessing exteral address internally.
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?

We have a new Cisco ASA 5550 that I am trying to configure. We are currently using a borderware firewall.
We have multiple external IP addresses and I can NAT traffic from all except for our external interface IP address.
When watching the packets in the ADSM monitor if the IP address is our external IP then I see nothing unless it is ICMP. I can ping the IP address just cannot do anything else with it.
All the rest of our provided IP addresses can be NATed and work correctly.
Traffic for our external interface IP does show up when we use the borderware firewall so we know the traffic is getting here.

I have a couple of ASA 5505's which work fine for what they are doing VPN and all that - we have 1 DLINK DFR-700 Firewall left and I need to get a new ASA to replace this since it is old.
All this box really does is port forward external clients to 1 address on the internal lan for client software updates. Any example configs?
So lets say we have client a with IP 1.1.1.1 and client b has 2.2.2.2 - at the moment this is what happens client a and b come in through http and get mapped to the internal http server 10.10.1.2
So I need to setup about 100 clients which can come in through http only - get mapped to the internal IP and also keeping the internal server to be able to access anything outside.

I have a cable modem internet connection and my cable modem is connected to an ASA 5505. The inside interface of the ASA has an IP address of 192.168.2.2 and is connected to a Linksys router's internet port which has an IP address of 192.168.2.1. The Linksys router then has a local area network of 192.168.1.0 and all my clients are on that network. Everything is working fine except in my ASA logs all the traffic shows up as the router's external address which is 192.168.2.1. I would like to see the 192.168.1.x address of the clients in the ASA firewall. I've tried making some changes to the Linksys router but that hasn't resolved it. Is there any changes I can make on the ASA to get this to work?

I know the CSS is too old but I have one in production environment and I was asked if it is possible to CSS to make NAT from inside addresses and translate them into one external IP address to diferent kind of communications, for example: 172.16.4.9 and 172.16.4.10 (inside addresses) should start connection to external IP addresses destinations 50.50.50.50 / 60.60.60.60 70.70.70.70 / 80.80.80.80 and so on, the default gateway to those Servers is the CSS and I would like to know if it is possible that all connection to external world to be translate into one IP address 172.16.4.100.
My CSS is 11503

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'm configuring a 5505 for a remote office. Until they are assigned a static ip by the provider I will have to use the providers dhcp address. How do I construct an access list for the outside interface using the external address if I don't know it yet? is there a commnd that will insert the ip address in to the access list once one is assigned?

I have a DIR-825 Rev. B1 wireless router running FW ver.NA2.0.7. I want to connect a Seagate 4Tb external HDD with USB 3.0 into the USB 2.0 port on the router to use the hdd as a NAS and run backups of the data files on the computers of my home network. The computers are running Windows 7 - 64bit. Plugging the hdd into the USB port on the computer lets it be recognized and ensured that Windows 7 had the most current drivers. When I plug the external hdd into the USB 2.0 port on the router and then plugging in the hdd and resetting the router, I still cannot get the computer to find the hdd on the network.

I recently switched routers to the DIR-615 and I'm trying to troubleshoot why one of our laptops keeps losing the IP address and gets a self-assigned IP address. I see the following messages in the log, I am wondering if the reason codes are listed and explained somewhere? I tried searching the manual but could not find any information.

I recently purchased the dir-655 router, and am impressed by it's speed. I had no problems configuring the router to my liking, and have found that all of my wireless devices communicate with it flawlessly.
However, my main reason for purchasing this router was for the USB port. I had hoped to connect my 2TB external drive and have it accessible by all wireless devices in my home. To my understanding, the USB port relies on the use of the Shareport Utility. I've installed the Shareport Utility to my laptop for wireless access to my media files for streaming.
Here's my problem. How can I access my media on my external HDD connected to the dir-655 with Apple TV2? I've read several options for PS3 users... and they all seem to involve leaving the pc/laptop running. I would ultimately like to bypass the necessity of leaving my laptop on... but if that's not a possibility, I can live with it being left on.
Therefore, is it possible to access the external drive connected to the dir-655 with my Apple TV 2 by using the laptop as a bridge? Can I access the content via Apple TV by using Windows SMB just as I currently do to access media stored on my laptop?
To summarize, I want to have access to the media on my external drive connected to the dir-655 via Apple TV2.

Both my DIR-655 and DIR-815, when setup as wireless access points, are unable to ping external IP addresses and thus cannot contact the dlink ntp servers. I've disabled UPnP, disabled DHCP, changed the LAN IP address to an available address on the network. The wireless works, devices are getting an IP from the network DHCP server and can surf the internet. But the DLink router itself cannot ping any external IP addresses.
