D-Link DIR-655 :: Refusing Local Connections - No External IP Address
Aug 22, 2011
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 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.

when I ping another workstation on my local network I should get back it's local IP but instead I am getting an ip address that resolves to somewhere in Germany! In fact if I ping any bogus name, I mean anything, it returns this same address 62.116.181.25. If I shut down my cable modem then everything resolves correctly. And yes I have DNS relay enabled because it seems to be the only way to get the workstations to resolve external sites correctly.

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.

I have a new Cisco 2951 router and I am trying to configure it for external users to connect to an internal ftp server. I created a firewall and added rules so as to allow ftp connections from the outside to the internal ftp server. I configured NAT so as to allow incoming connections through the router. I have been unsuccessful so far in trying to make this ftp connection work.I am using a zone-based firewall and for the particular ftp rule, the action is inspect so as to allow stateful inspection of packets.

Recently I'm having issues with accessing local services via external IP. Short description of configuration:
- sub.mydomain.com pointing to my external IP.
- few web services running on my local server with reverse proxy on Apache 2
- firewall on router enabled
- ips on router disabled
- single port forwarding: WAN 80->Lan 443, WAN 443->LAN 443
- accessing my services via sub.mydomain.com/service1, sub.mydomain.com/service2, etc
- I had to create a new rule in internet access policy allowing LAN, any, any to
Basicaly if I go no matter if I type http or https I will be redirected on 443. That configuration has beed working without any issues for a month. Recently I have increased the amount of DHCP users and suddenly it's not working any more. I can still access my services from outside but not from LAN.Restarting router does the trick for a while,sometimes for few minutes, sometimes longer.Enabling IPS is the way to go but then I'm limited to around 22Mbit/s. I have no idea what happend.What I can't understand that it was working, suddenly it's stopped and there are two solutions, either to enable IPS or to restart router?

I'm using a Netgear WGT624 Router for my firm's intranet. At home I'm using a router called NSW-R2 by Gembird..
What I want to do is connecting my PC at home (Windows XP) to my firm's intranet so I can print on my LAN Printer or edit files on my NAS.
I've heard about VPN tunnels, but I don't want to keep my firm PC on 24 hours a day. So is it somehow possible, to build a VPN or something similar by only using the Netgear WGT624 Router?
Edit/More Information: I've steup a DDNS. My Router supports Port-Forwarding. I'm currently using Remote Desktop. Both PC run Windows XP Professional.

I have a couple WinXP Pros and Win7s connected to the same router wired and wirelessly. All of them have Remote Desktop enabled (via System settings) and have Windows Firewall exceptions setup. They all have AVG Anti Virus and no other firewalls installed. They all also have static ips assigned.Windows file sharing is working fine between all of them. VNC also works with no problems.But for some reason, I could not get Windows Remote Desktop to work between any of themAnother weird thing that may or may not be related is that they can't ping other computers on the same network.This leads me to believe that this might be a networking issue.I have a DLink router (can't remember model) with a Tomato Firmware.I do not have port forwarding setup for Remote Desktop because I think (although I may be wrong) that they are only used for connecting from the internet, which I don't need. I only want local connections right now.

I am using a 6500 with FWSM. I need to separate an internal server/HQ network from 3 or 4 different external connections. The external networks do not necessarily need to be isolated from each other.I have the option of using a 3 layer model: L2 Access layer to SVIs on the Distribution layer and then L3 to the 6500.L2 Access, connecting directly to the 6500s, with the SVIs on the FWSM.Is it better to have the FWSM outside the MSFC or Inside? Am i correct in thinking that "inside" vs "outside" is determined by whether the SVI's are configured on the FWSM or the MSFC? is there any performance impact from having the FWSM doing the routing instead of the MSFC.If the vlans are all configured on the FWSM, what is the 6500 doing, other than providing switch ports?

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.

We have just swtiched router and network in out house and upon doing so my computer can no longer connect to the internet, the other two in our house can. The computer can detect the network but the information it has about it is wrong, the security type and radio type. (See picture) it is a Billion Router and works fine on all other computers, we thought at first the problem was with Hamachi but after uninstalling it the problem was not fixed.

After cleaning the infection, none of my browser will work.Firefox display this message: "The Proxy Server is Refusing Connection".IE displays an error as well.I can't even use Steam's (game client) browser to see what games they have available but I am able to sign on.I am sure my internet is working because I am able to log on to my Instant Messaging Program and chat with freinds and use a VoIP software to talk with friends without issue.The problem is happening on my "regular" windows account.My administrative account seems to be problem free as I am able to browse the net like I had before the infection.

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?

I have migrated my ACS data from 4.1 to 5.1 and everything is working fine to test the connection I have configured a switch to get the authentication from the new Tacacs server, using my old username and password..i got in perfectly but when the switch asked my for enable which is the same password, it refused the password.(I have unchecked the <use a different password for enable> option) I deleted my switch from the Tacacs to enter locally, I went in with no problems..i thought that the problem may be from the old configuration.so I created a new username and password to check, and the problem still exist.

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]......

The original network had a Zylex router, Netgear Switch. There was 2 pc's, one XP and Win 7. There is also 3 tills connected too. There is VPN network connected too. This emits a wireless signal to connect to a scanning gun and is also used to administrate the entire network. I was told by the Administrator of that network that it shouldn't interfere with the wifi network.
The job I was requested to do was to install 3 new wall plates as the Win 7 pc was using a Belkin wireless adapter. There was 2 put inside the office where the XP and Win7 pc's are located. The 3rd was just outside the office.
Now all the ethernet connections work 100%. The wifi is another story though. It will show up in the connect too, when you try connect it will disappear/no response from AP/connect then disappear, these are random too. No order to when each is error is displayed. Even when I put in another router the exact same issues happen.
I have tried to connect to both routers wifi when it wasn't plugged into the switch. Just the router's turned on with no cables plugged in separately of course, no joy same issue with both.

Our College uses Ethernet connexion for its students with the IPv4 Address of each machine configured using DHCP (not manually). In order to prevent students from playing certain online videogames some ports are blocked for all machines on the network, but they can be manually untagged (ie for competitive play). The problem occurred when we tried to untag the ports to allow online games on this machine. After the allowed ports were modified, the machine refused to assign an IP adress to itself - no matter how many times we try to renew the DHCP Lease. Restoring the previous set of allowed ports fixes the problem, but doesn't allow for online play.
config: OS X 10.8.2 with nothing fancy. Other machines on the network do no experience this problem.

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.

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 set up a server running Windows Server 2008 which two remote users can dial into using a VPN connection. It works fine unless they are both in the same location, in which case only one of them can connect. If one is connected and the other one tries to log in, it normally kicks out the first connection.I think this is because the PPTP protocol cannot cope with two VPN connections from the same IP address. Is this correct? If so, what can I do about it? Is there a work around, or would one of the other VPN protocols work? If so, how easy is it to set these up (I'm no IT professional)?Please note that the remote location in question is in a serviced office, so I'm not in a position to change or play around with their router.

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.
