Routers / Switches :: Can't Access Remote System

Aug 19, 2011

I am trying to connect to my office PCs via VPN and/or RDP. The office uses Qwest DSL and has a dynamic IP address. I use to keep the DNS updated with the WAN address of the router. However, any attempt to access the network fails. I have tried remote management access (I enabled it on the router) but that fails. I forwarded RDP ports on the router to one of the PCs but can't connect to it. I also set up a VPN server but cannot connect to it either. Something tells me that all requests to are not getting to my modem/router. I have even tried the IP associated with the name (Yes, I did check that it is correct!) but nothing works there either.

Cisco Routers :: SRP 527w Is Not Accessible

Jul 28, 2010

I recently ( three days ago ) purchased a SRP 527w and have been using it in a mixed Mac/Windows network. The setup is currently primarily using defaults apart from enabling logging. While I was still able to access the internet with some applications, accessing web content appears to have blocked after approximately 48 hours uptime.
No web pages using port 80 were available and that included the router web interface. The router would respond to ping only.
On a different note. I have to say that I find it very strange that the supplied documentation doesn't advise setting up the router using the admin login. It was only after reading one of the comments on this site that I was alerted to this security problem. I also find it rather annoying that I appear to have to purchase additional support merely to be able to download firmware updates which are designed to give the device improved functionality.

Cisco Routers :: UC540 - Second Public IP Not Accessible From Inside LAN

Apr 2, 2013

I have a client that just got a second public IP (x.x.x.252) for a new program. I've setup that second IP on their UC540 on the public-facing port and it's accessible all day long from the outside, no problem. The problem comes in where users from within the LAN can't see the new public IP at all; however, they CAN get to the original public IP x.x.x.250. I've looked at the rules every which way and can't see anything that either 1) only allows LAN traffic to get to the original public IP, or 2) a NAT rule that only allows the same thing.
[Disclaimer: I just inherited this client and their setup, so other than me adding the IP and opening ports to it, I didn't program it.]
Here is the port configuration:
interface FastEthernet0/0
  description $FW_OUTSIDE$
  ip address secondary
  ip address
  ip access-group 106 in
  no ip redirects
  no ip (code )
I can't figure out why .250 is internally-accessible, but .252 isn't. .252 is in the routing table as a directly-connected address, but I also added ip route FastEthernet0/0 to the routing table and it still won't go. Everything is controlled by the UC540: The internal servers do not run DNS or DHCP or even a domain. There are no NAT outside rules.

Internet Accessible But Cannot Access Other Computer On LAN

Aug 15, 2012

I have a Windows 7 machine that is wired to the router. I have Windows XP computer that is wireless in another room. Signal is showing 80% and internet is accessible and fast from both systems; but, I cannot access either computer from the other computer. I got the IP addresses of each machine and I cannot ping from either direction. Firewalls are turned off on both systems.When I type in \server, I get an error that say I should check my spelling or use the windows Search; but, that doesn't work.

Internet Accessible But Unable To Browse Anything

Apr 19, 2012

My pc (windows7) will say its connected.. It even says internet access.. But when I click in the Internet?THE WEB PAGE IS NOT AVAILABLE. It says the DNS lookup failed. But the thing is... all my friends bring their laptops over (Mac & Pc) and try work fine. Even my phone catches the wifi perfectly in my house. I started to think maybe it was the laptop but the laptop word great on wifi at my job, my friends house, and pretty much anywhere with wifi but my house. I have wifi through bright house and they came to my house one day but they ended up not doing anything because they can only make sure there device (router) works perfectly. Ok.. So I took the laptop to best buy's geek squad and the guy "reseted my network card" & told me it should e fine when I got home.. Nope. Didn't work. I have spent hours looking trough the Internet trying things that people recommended I do. (start, run, cmd) I've tried it all. It just won't work. I really need this laptop to work at home because I do a lot of work from the pc. I hope somebody on here could point me into the right direction before I give up & toss this laptop in the shed and be forced to purchase a new one.

Routers / Switches :: How To Connect Two Internet Routers To One LAN

Mar 8, 2011

How do i connect two internet routers to one IP address range?I currently have one broadband router connected on subnet, I have a second line which is a copper ethernet EFM 2Mb line connected using a Cisco 1800 router configured on subnet, no DHCP is configured on either router. the dhcp is provided by a windows 2003 server on our LAN which is also configured on the same LAN IP range. if i connect the Cisco router into the same switch as the broadband router my network devices stop working and dont respond.

If i check the broadband router it shows all the connections to it as having the same MAC address as the Cisco router?? if i disconnect the Cisco router everything returns back to normal and works perfectly.What I want to achieve is to be able to run both routers on the same LAN to provide internet access by configuring the pc's to route through a specific router. the DHCP I want to stay routed through my original broadband line. at the same time i want all pc's to access to the lan devices (ie. servers and printers) what the correct configuration would be for the two internet routers would be?

Protocols / Routing :: IP Camera Not Accessible Through Internet

Feb 28, 2012

I purchased an IP Cam for my girl friend to monitor her dog, she lives in an apartment complex that provides internet. I have been able to get the camera setup at my house to be accessed through the internet. I have a cable modem and a router, setup a dyndns account, port forwarded my router and boom it worked. Went to my gf's apartment and I didn't think of it at first until I was frustrated, but realized the apartment complex probably has a router of its own. I can access the cam on her LAN but not through the internet.

D-Link DIR-655 :: Internet Accessible But No Network Access

Mar 4, 2011

Internet access is working fine, however I cannot get my computers to work on the network therefore cant share any files or play any network games.  The router is set up as DHCP server therefore IPs are automatically assigned, this is setup on the PCs and the router.  The work group is also set.  Exactly same settings basically as my old router which worked fine but wont on this one!  I have 3 wired PCs and a wireless laptop.  2 PCs are windows XP the other is Windows 7 and the laptop is windows 7.  The wireless win7 laptop will recognize my win7 wired PC and vice versa and can share everything without problems, but they wont have anything to do with the wired winxp PCs, on top of that the 2 winxp wont recognize each other either so don't think its anything platform specific. I have also tried setting up static IPs for each computer - still no joy.This is a brand new D-Link DIR-655 Rev B1 firmware 2.00

Windows 7 Can't Receive Internet Network Traffic - Gateway Accessible

Aug 18, 2012

I just got my dad's old notebook (VAIO VPC F223FB) which is better than my older one. So, I did a backup and then managed to clean install a Windows 7 Professional x64.At first I had a problem with the drivers, because the internet wasn't connecting and the USB ports weren't detecting my External Drive. So, I tested other USB port and got it. Installed the drivers and I could connect to the wireless network. But it doesn't detect the ethernet cable! And I want it detecting because then it's faster. I already tried downloading the Ethernet Controller driver. At first, I downloaded through Sony's support site but it didn't recognize the driver. Now, it recognizes but still doesn't connect it. And when I tried Solving Connection Problems, it said the network gateway was accessible but Windows can't receive Internet network traffic.

D-Link DIR-601 :: Configure Router To Make Website Accessible From The Internet?

Jan 25, 2012

I have IIS running in a machine inside my network and I would like to make is visible to the world wide web.To do that, I created a website in the port 8787, which is accessible when the user types in the browser. Of course it works only when the user is inside my network.(IIS running over windows server 2008 OS)Now I want to make it visible to the WWW, so I created a rule to make a port forwarding to it:I went to: Advanced > Virtual Servers and created a rule with the given information:

Name: website
private ip:
protocol: both
private port: 8787
public port: 8787
Schedule: always

This rule created automatically a firewall rule

Source: WAN *
Destination: LAN Protocol: * Port range:8787

Unfortunately it isn't enough, if I type myPublicIp:8787  I can't access the website because I either get "connection reset" error or a timeout.I pluged my computer directly in my modem and it worked perfectly.To make a test, I tried to enable the router remote administration on the port 10001. It didn't my wireless router is a dlink di-524, I am writing this in this forum because I couldn't find the one related to my router...

Cisco Switches :: Virtual NIC On VOIP System And SG500X?

Aug 27, 2012

We have a VOIP system with 1 physical NIC attached to our SG500X. It has a virtual MAC address along with the physical MAC address. It has 2 IP addresses tied to it.
I can ping the physical IP address, but can only ping the virtual address from the same vlan as the virtual nic. However, if I clear the arp table, a few pings will go through until they all time out again. This is causing problems on my phone system, and I need to establish this communication. I have tried putting in static MAC and ARP entries, but that does not work.

I tried to reset the Netgear Router, shut down and restart and still the same problem. I plugged the computer directly into the cable modem and everthing works just fine. I'm guessing something happened to the Netgear router but I don't know if it is a setting or something happened to the router itself. The router is about a year old. I can use the default to get into the router but I'm not sure what settings I should try to change.
