What are the most common cause for a "could not connect to host" problem?The firewall is not blocking anything, and even with the firewall disabled, the problem still occurs. With "Server" service turned on, the problem still happens.Windows xplso the server couldn't find any trace of a connection attempt, so my attempts to connect never actually made it to the server.

I have a host that can successfully connect to a PIX 515E (7.x OS) via VPN Client; however, I have no IP routing to the LAN from the remote host.The VPN IP pool works finem,The LAN default gateway is the inside interface on the PIX; the network is flat L2 behind it.The default route on the PIX points out; no other routes are defined,The VPN remote host can be pinged from LAN hosts, but the VPN remote host cannot ping any LAN host, not even the PIX inside interface.

I have been looking all over the place for the answer of how to allow clients on an IPSEC VPN to ping from host to host.
My host has an IP of 20.168.1.2 from a router DHCP. I have a virtual environment which has a DC and DNS and the IP is: 192.168.1.x how can I get access from my host to the virtual environment? What do I need to setup on the host OS? (Windows)

View 3 Replies View RelatedI've got an 1841 router acting as the firewall for a LAN. It also does NAT and acts as the dialer for a PPPoE DSL line to the internet.
All is working fine, except now I need to allow a Tivo device to connect to certain ports on the Tivo servers on the internet. I want only the Tivo to be able to do this. The problem is that NAT is happening before my outbound ACL is checked, so even though I've got rules to allow the Tivo's LAN address out on all ports, it never works. I've verified this using a syslog server, and can see my external DSL IP trying to connect to the Tivo servers and being denied.
I've done things like this at work by NATting the appropriate internal host to its own external static IP address, which allows me to write rules allowing only that external address to do stuff. But I don't have multiple external addresses to work with here.
I tried applying my outbound ACL to the LAN interface of the router in the "in" direction (and removing the same ACL from the Dialer interface in the "out" direction), but that broke other things like the router's own ability to ping out to the LAN or to see a TFTP server on the LAN. I could maybe fix all of that with rule changes and inspect statements on traffic going out toward the LAN (not sure of this, think so), but I'm wondering:
Is there a better way to let just the Tivo makes outgoing connections to certain ports?

My internet connection started to disconnect after an office mate used my PC. I thought it was just the cables but it's not. I pinged my ip address and its okay (sent=4; received=4). But when i ping Yahoo! and other websites, it said that "Destination host unreachable" (sent=4;received=0;lost=4;100% loss). What should I do to make my connection okay? I didn't ask assistance from our IT personnel bcoz they said if i want to reconnect/reinstall connection, I have to get an approved request from our bosses. And I don't like being asked bcoz they are like tyrant bosses.
View 2 Replies View RelatedWhen I try to ping ipv6.xsnews.nl on either of my Windows 7 computers, it returns "Ping request could not find host". But when I do it on XP, it succeeds. I have tried putting the W7 PC in the DMZ, disabling the software firewall but it doesn't work.
What I think it involves is having ipv6 installed on each. I tried to duplicate the setup of both the XP and a W7 computer, installing the gogo6 tunnel. But apparently it's not setup on this computer because the ping result is the same as on the third computer which hasn't had ipv6 installed. s not setup on this computer because the ping result is the same as on the third computer which hasn
Small office setup with a wireless modem/router. We have two computers that are identical HP Pavilion a6807c PCs running Vista Home Premium. Other computers in the office are a bit older and run either XP or Vista.Just purchased a new HP Officejet 7000 printer and connected it via a USB to one of the HP Pavilion Vista computers (which I will refer to as HP1). The printer works fine on HP1 using the direct USB connection.Set printer sharing, file sharing, and even public sharing on both HP computers (HP1 and the other one I will refer to as HP2). Workgroup name is the same. Can access HP1 and see the HP printer on HP1 from other computers in the office. However, when I try to connect to the printer from HP2 to HP1, it locks up HP1 and HP1 requires a hard reset. I tried installing the software/drivers on HP2, but HP2 still tries to install the drivers from HP1.I am not sure its a problem with HP1 as much as it is a Vista issue. The reason I say this is because I have been able to successfully use an XP computer (XP3) to connect and print to the Officejet on HP1.

View 2 Replies View RelatedI have a host machine (Laptop, Win 7 Home Premium x64) running Windows 7 Ultimate x64 on VMWare Workstation 9. I've got this system set up for UMDF driver development, because I need a target machine to debug drivers on. However, because I'm developing drivers for Win 7 (x86 and x64), I cannot connect to the virtual machine on via a simple network connection. Connection methods are outlined here.
I have tried a few different pieces of software (mostly Eltima software), and have Google'd every combination of phrases that I can think of. I can't find any information on this anywhere. I don't just need to share data between the machines, I need a more "physical" connection.
Does any know how to do this, or if there's another (preferably more simple) way of doing it?
The Lg840g is a tracfone with wifi capability. I get strong wifi signal and connection at home, but receive failure to connect to requested host message when I open the browser.

View 1 Replies View RelatedI am learning to write ACL's along with a billion other Cisco things. The internet is not clear on how to do this exactly. At least in my research.
I have two host on the same subnet and I want to block all except RDP TCP port 3389 from one host to another.
I want to apply that Access-group to a switchport interface on my 3750 that belongs to the computer I want to protect from the other.
Host A: 10.1.1.10/24 -- I need to block all TCP and UDP traffic except for port 3389tcp
Host B: 10.1.1.60/24 -- I need to allow only TCP port 3389 from Host A to this one.
This is on the same switch so I can use an extended ACL like 101 or whatever.
This is almost starting to make sense to me but im still weak on extended ACL. I got basics down pretty well.

I downloaded the HOSTS file from winhelp2002.mvps.org, hoping it would better my security. However, now some pictures that used to show either show the "Internet Explorer cannot display the webpage." or just have the X box thing. I'm guessing this problem results from the new HOSTS file. What should I do? Should I revert to my old file? If so, then how can I do this?
View 4 Replies View RelatedBasically, I am swapping my Atom/ION nettop (that I use as a file server, game server, torrent server etc. etc.) for one that has no fans and no mechanical HDD. I control it primarily via RDP, so I don't need to plug a keyboard or display into the nettop itself.
The new one I'm getting should be a step up due to the whole no moving parts thing, as well as the much faster CPU. But Intel, in their infinite wisdom, have not provided (and don't plan on providing) a 64bit graphics driver for the GMA 3650.
If I were to install 64bit Windows on this new machine without installing a driver for the graphics, would I have any issues using RDP? I'm not sure if the visuals are generated on the host or the client and whether it would matter either way.
