[SOLVED] Linux cannot ping gateway server within a Windows networking environment
location: linuxquestions.com - date: July 11, 2011
I am trying to get a Linux (Slackware 13.37) working in a Windows networking environment. The IT support for this organisation does not extend to Linux support, so I'm limited in what help I can get for this.
I'm trying to get to the point where I can get to the internet to download what I need on this Linux machine.
The situation is this (*fictitious addresses used) -
My Linux machine uses a fixed IP address (10.100.150.21)
My Windows machine uses a DHCP assigned IP address (10.100.150.213)
Both Linux and Windows machine are configured to access the gateway server (10.100.150.1)
So, I can ping the Linux machine from the Windows machine and vice-versa.
I can ping the gateway machine from the Windows machine.
I can browse Windows Shares on the network via SMB from the Linux machine.
I CANNOT ping the gateway machine from the Linux machine with the Destination Host Unreachable message being the error message.
For actual internet access I need to access a proxy
Need to create a gateway server to ssh/telnet other servers
location: linuxquestions.com - date: March 20, 2013
I have 5 Redhat Linux servers. I want to create one of them as a gateway/jump box servers through which I can ssh/telnet to other 4 remaining servers. Although I want to create user account on only the gateway/jumpbox server.
Example: - In my comp we have a server on which our user account exists and through this we can "sudo ssh" to other servers.
Could anyone help me out with this?

Locking down an office network with a gateway server
location: ubuntuforums.com - date: August 5, 2010
I am looking for some advice on how best to lock down our office network to keep our employee's from wasting time on sites like facebook and youtube. This will be my first time setting up a server as a gateway in a production environment so I thought I should get some suggestions on what the best packages would be to do this.
I essentially need to lock down our network so that i can monitor what everyone is doing on the Internet and block it if needed. it doesn't have to be web based or have a bunch of gui's, im fine with command line, configs and log files, but it would be nice.
I'm interested in commercial products as well as long as they are linux based.
Any suggestions would be great.
Firewall/Gateway + Server
location: linuxquestions.com - date: April 27, 2006
I have an old computer (not that old, PIII 866MHz, 256RAM, 4GB HD) and I wanted to turn it into a Firewall/Gateway as well as a server. My current router, a D-Link DI-604 isn't very strong, and it bogs down as soon as I connect to a torrent, or do a lot of things which take advantage of UPnP, so using an old computer would surely be a lot better. I also run a small site, and since I don't get that many visitors, I would like to run it myself.
I want to know how I would go about doing this. I looked at some solutions such as IPcop, or Coyote Linux, but they don't seem to be able to support Apache, MySQL and PHP. I'm guessing that I would probably need to use a general distro and just have seperate software take care of everything, but I'm not sure how I would go about doing that. The Firewall/Gateway component would have to be able to support UPnP, as well as a feature to disable the network during certain hours, and many other kinds of things that routers tend to do. I'm willing to

PPTP with Centos Server & Win 7 client not providing default gateway
location: linuxquestions.com - date: August 21, 2013
I am trying to setup a Centos 5.8 box as a PPTP server - it worked in the past and no longer does.
My issue is that the client (win7) receives 0.0.0.0 as default gateway and hence cant route anything. Cant ping the Centos box on the vpn @, cant access the web. When I uncheck the use default gateway box from win7, I can reach the Centos box.
I've disabled (temporarily) all iptables rules but the -A POSTROUTING -o eth0 -j MASQUERADE - I have /proc/sys/net/ipv4/ip_forward set to 1
Any suggestion as how can the server provide a correct gateway address to the client ?
Tks in advance
pptp version is 1.7.2-8.el5
Ubuntu Server 12.04 Cannot ping gateway but pings all local PCs
location: ubuntuforums.com - date: June 30, 2012
So I just finished installing Ubuntu Server 12.04 on a PC.
I setup SSH and setup static IP. The server can ping ALL my local computers just fine, but NOT my gateway (router) and NOT any internet IP. My 5 other PCs ALL ping the Ubuntu server, the gateway, and internet IPs just fine. No IP conflicts exist either.
My network uses 10.1.1.x for the IP.
My gateway is 10.1.1.254.
The Ubuntu Server is 10.1.1.252.
From my windows laptop I login to the server via SSH no problem. ALL local connectivity works, EXCEPT from the server to the gateway.
EDIT: Found someone with the exact same problem: http://ubuntuforums.org/showthread.php?p=12064102
I had no network connected during the install; maybe that caused a glitch on the setup of the network systems?
Here's my /etc/network/interfaces file:
iface lo inet loopback

DHCP Server no longer respones to DHCP Requests, can't ping gateway
location: ubuntuforums.com - date: October 22, 2010
Back in April I set up a Ubuntu DHCP server and a multiple VLAN network (http://ubuntuforums.org/showthread.php?t=1465860&page=3) to migrate our various servers, workstations, etc off the 192.168.1.1 /24 network that everything was on because we where running out of address space. I built out the new network and everything worked great except our AD server would never get an IP address from the DHCP server (static reservation) and even if I set the IP statically on the AD server it couldn't ping the gateway and noone could log in. After several attempts to resolve this, including bringing in outside help, we where never able to figure out what the problem was.
Now 6 months later I have time to revisit the issue without effecting the live network. I used Acronis and imaged the AD server last Friday, cloned it on to another box with the same hardware, and put it up on the new network that's been sitting unused for the last 6 months.
Today when I statically set the IP on the AD ser
