Hi all,
I really hope I'm not doing anything dumb here. I've got Ubuntu 10.04 on my laptop and have recently (within the last 72 hours) started having trouble connecting to other machines on my local network. I'm unable to ping both my router and a server set up in the room beside me.
1. I have tried pinging my server and router from other machines and it works fine.
Here is my network infrastructure.
there is a problem in my network.
server M,A,B,C,D have public ip address.
people who are outside of my network can ping server M at anywhere, but they can't access server M.
server M can ping any ip address on the internet, but it can't access any ip which is outside of my network.

I am trying to configure a (relatively!) simple VPN on my Windows Server 2008 R2 box.
I'm trying to setup a small LAN, using an Ethernet switch, an Arch Linux server, and around 10 Windows XP machines. This network has no outside connections.

Hi, I'm a little new to linux and networking. I have a small server that I want to use as storage for my home network. I have a wireless router acting as a bridge that is getting wireless signal from our main router in the home and turns the signal into wired for my network. I have a 8 port switch hooked to the router which all my computers are connected to.
I have a home server running Ubuntu 11.10.
It is currently configured to have a static IP address via my router.
I also use a Dynamic DNS service built into the router to update my domain name to point to that statically assigned domain name.
I can access the server via SSH using either the internal IP address or the domain name.
