Cisco Switching/Routing :: 880 W Router - Remote Computers Can't Connect To Target Machines
Jun 20, 2012
I have and 880 W router. The LAN members can get out t o the internet. Now I want to configure NAT such that outside computers can access a couple of the machines using Remote Desktop (RDP). I am using Configuration Professional.
When I configure inside to outside, the remote computers can't connect to the target machines.When I configure outside to inside, the target machines acn't get to the internet.
When I try to use the advanced NAT definition wizard, I can't complete the task because the only inside pool (?) or LAN (?) is "designated" and not available to select. I can't free it up without deleting the one working NAT entry which is the one that enables all computers to reach the internet.

We have to connect two 3750G switches to some HP machines. Those machines have several network interfaces, which are going to be configured in several bondings. The load balancing mode they want to configure is mode 6, alb. We have investigated and it is: [code] Receive load balancing is achieved through ARP negotiation.We would like to know if it is supported to be connected to a 3750G an if an special configuration is needed.

I have two ACS 5.2 running as primary and secondary instances respectively. When I try to delete a remote log target under System Administration > ... > Configuration > Log Configuration > Remote Log Targets I get the following error message...."The item you trying to delete is referenced by other items. You must remove all references to this item before it can be deleted".
I have searched the configuration within the web gui and was unable to find anything that reference the object that I'm trying to delete.

Today when we run one applcation to access a target server with IP address 10.2.2.13, the application cannot run through and appearing error message related networking.The target server has two network ports whereby another one with IP 10.2.2.14 is running OK with the same application. All these two connections are connected to the same Cisco switch 3750, after the switch then go to Cisco ASA firewall which has no access control rule for this 10.2.2.13 and its subnet, and then the firewall connect directly to the application server.We can ping, remote desktop access and telent port for the application to the target server by using 10.2.2.13.We swapped the cable connection of the ports from one another and try the application again, the IP with 10.2.2.13 is still fail and IP with 10.2.2.14 is OK.We then change the IP from 10.2.2.13 to 10.2.2.12 or 10.2.2.155, all are OK. We changed back to 10.2.2.13, it is failed again.The switch is in running real time production and so we cannot power cycle or reload the switch.

I've just set up DHCP Snooping and IP Source Guard on our SG500 series switches. It seems to work quite well, except when a wireless host roams from one AP to another (on a different switch port), all traffic from that host gets blocked.
I can understand why this is occuring, but I don't know what I can do to work around this problem.had success with roaming WiFi machines in conjunction with IP Source Guard?

I've got an RV042 router at home and am connected from my office via the QuickVPN client ver 1.4.1.1.2. I can ping the RV042 and log into the administration page and make changes. However, I can not see other computers on the remote network. I can not ping them. When I open my Network page, I still see the computers on my local network.
All machines are running Windows 7 Ultimate. ISP is Comcast at both locations. WAN IP's are dynamic, but have not changed in over a year. Local IP's on the remote (home) network are static..[url]....

I am just setting up a simple scenario with a 1841. Server @ 172.31.1.1 cannot ping 172.31.0.254 or 172.31.0.105. It can ping 172.31.1.250. The router can, on the other hand, ping devices on both networks. This is just for testing routing theory so I don't know why hosts on either side of the network cannot ping each other.
I am only using the FastEthernet interfaces on Router 1841.

I have 3 machines running windows XP, they all belong to my company's domain. These machines have to leave our office but still have to be able to connect to each other and share a few folders on each. I used to do this all the time. I would make sure to turn on the "Server" service, set the windows firewall to allow File and Printer sharing, set the File and Printer sharing setting in the Local Area Connection properties, and set the proper sharing/security of the specific folder. Then as long as each machine used a specific local logon name that was the same on each machine, they would all connect to the shares and work perfectly.However now, I seem to not be able to get any of this to work on machines that have service pack 3. Is there something in sp3 that breaks this?Isn't there a way to still share files on these sp3 machines even though I'm not on the domain? (without changing the domain membership)

I am using a Dlink 655 router. On the inside are DHCP systems. On the outside is my server. I cannot seem to get the inside machines to recognize my file shares outside the dlink. The outside server is a MAC mini. Any machine outside the server can see the file shares (regardless if they are a Mac or a Windows PC - So I know that SMB is set-up properly).How can I get the inside servers to see the file shares on the outside machine?

I have a Windows 7 machine sending shares across the network. Other Windows 7 machines have no problems connecting, but XP machines cannot connect. (Win7 can connect to XP shares).
I have adjust every setting that I have seen to no avail. This includes turning off HomeGroups, turning off password. Removing my password from my user account. Adding "Everyone" to each of the shares. I have even messed with the Local Group Policy Editor to send unencrypted passwords to third party SMB's.

I have just had my broadband upgraded to FTTC which means my router has had to change. Previously I was using a Thomson TG585v7 ADSL thingy provided by my ISP. One nice thing about that router was that it would act as a local DNS and allow me to find my other machines on the network by using <hostname>.lan instead of IP addresses.
I've now switched to a Linksys WRT320N ethernet router which connects to my fibre modem, and which I've updated to the latest firmware (1.0.04). I have 2 machines on the network which I regularly want to connect to each other; one is running Windows 7 and the other is running OS X Lion.
The problem I'm having is that I'm unable to connect to my Win7 machine from the OS X machine using the Win7 machine's name. However, I'm able to ping the OS X machine from my Win7 machine using the hostname.

i want to setup a remote desktop connection for 3 computers on the same network to connect to remotely. Originally i was going to port forward the original windows RDP port and run the windows rdp service but learnt that XP Home Edition doesn't support this feature. I want to be able to log onto these computers at any time remotely with the need of accessing the computer before i connect.

Everything was working fine, and various computers, tablets, and even my smartphone, all hooked up to my router without any problems. Somehow, this week, first my Asus U56E wouldn't connect (before all this it was automatic), and then my Google chromebook wouldn't connect either. The Asus is my main computer. And the reason for writing. I just mention the chromebook because they both quit connecting at same time, pretty much. But still my old xp netbook connects, as does my new google nexus7 tablet. And my nexus one phone. All hook to wifi, with no problem.I tried everything I could think of: This is a Dlink Dir615 router. Even set a new wireless network up, but it doesn't seem to connect. I ran the Windows Network Diagnostics, and it reset everything, and looked like it was fixing it, but no go. It said to investigate router or access point issues. I did what it said, and what has always worked with these problems. Turned off router for about 1/2 minute, then restarted it. Then did the same with the Cox motorola modem, *and* the router, but still, just doesn't want to connect. Wireless, that is...no problem with ethernet.Finally pushed the little pin in in the back of router, and reset the router entirely. Set all up again. Same thing happens, it just doesn't seem to recognize these two computers. So just to be sure, I used my nexus one as a wifi point: and these computers hook up fine, so it seems to be something with the router. My ISP is Cox. Cable. Router D-Link Dir 615, latest firmware. Modem Cox issue Motorola Surfboard. Antivirus Microsoft Security Essentials, and Win7 Firewall (I tried with these two turned off, but still no).I include the xirrus app's output...My wireless network on that app is 'phubai' and that is the one that won't connect. I had trouble bringing it up on Xirrus, too. It would only show when I would attempt to connnect, then it would disappear again.

I am administering a Catalyst 2960S switch and I would like to connect several computers to it. Some of those each have a static IP address. For a few of them, I would like the switch to dynamically assign an IP address to them via DHCP. Is the switch capable of doing this? If so, how can I do it? I tried looking through Cisco Network Assistant and I couldn't find it. Some web pages have suggested I telnet into the switch and issue commands like "ip dhcp ?" to see what commands are possible. I can telnet in and if I type but I get an "Unrecognized command" for both "ip ?" and "ip dhcp ?". This makes me think I'm reading the wrong web pages. I did come across the term "DHCP snooping". It seems relevant, but very difficult for me to grasp.

I have a SMC Gateway Router and 2 computers connected to it with RJ-45 cable. They are (1 iMac + 1 PC) 150 feet apart both computers are wired to the router. I also have a Canon Pixma MP 560 Multifunction Inkjet printer that has the capability to be connected both wired and wireless. Right now it is only connected to the iMac via a USB connection as all 3 (router, iMac and printer) are on the same workstation.how to connect the printer so it could also support the 2nd computer a Windows PC which is located on the floor below. Can I do that through the wired router too? If not possible, I also have the capability to connect wirelessly although I would prefer to use the wired connnections.The PC has a Belkin USB 2.0 Network Adapter for wireless connection; both SMC Router and Belkin USB adapter are 902.11 N capable.

I have been searching the net for a hub of some sort for a home office. I need it to be able to support printers. It needs to be a wireless router and have a data storage which can be accessed by multiple computers. Like a backup. But the main thing im worried about is if it can be protected by antivirus and stuff.
