VPN Connection established, but I cannot ping or connect to any machines in the network
Posted on 2004-11-19
Hi, I am trying to connect to the network at work. I have setup the VPN connection and it seems to work, I can bring up the work router web configuration page using a local IP address, but I cannot ping any machines in the network. I am trying to connect to my PC at work using VNC. I have disabled the firewall on my PC and my PC at work. But nothing seems to work. Eventually I would like for it to work with the firewall in place which would be more secure.
The first time I tried it, it worked for a little while but then the router crashed. I later found out this was probably because I had "use the default gateway on the remote network" selected. Apparently this is known to cause routers to hang. My colleague at work tried to make some changes to the router to help me connect, I think he has stuffed it up as he was not sure what he was doing. I have told him not to change anything any more :)
I have been able to connect again but I can't ping anything or connect using VNC. I even tried turning the "default gateway on the remote network" back on to see if that worked, but it didn't. I turned it back off again before it crashed the router again. The router has an option to ping an IP address as well, but that doesn't work either. I think the reason this is happening is because the settings on the router are incorrect.
I am running Windows XP on both my home PC and work PC. They both have SP2 installed. The router is a Snapgear SME530. I use a 512 ADSL connection at home and work has a 1Gb ADSL link.
If anyone could help me I would really appreciate it, I have studied networking a bit as I did a semester at Uni on networking. I would be really interested in finding out why this is happening as it would help my study allot. I have given this question 500 points as I am hoping someone may have the patience to solve this with me and show me a way to diagnose the problem logically. It might be a bit of work as I don't think the router settings are optimal and I would really like to learn what are the correct settings and why that is.
If someone just wants to get me connected but doesn't have the time or inclination to explain why and to go through the router settings with me, I am happy to split the points if someone else is interested in going through settings and the reasons why with me.
I will post whatever information you require to diagnose this problem, just let me know what you need.
