Hello, (Firstly I'd like to apologise for the question being so long!)
I have a problem that I have been struggling to solve on my own the last couple of days and i'm totally confused now if I'm totally honest with you. I'm hoping that I will be able to work home on my laptop and connect to files on a new pc that I have recently purchased and put in my work office. I also want to be able to be at home from the laptop and be able to use the printer which is also at the office. This is just so I can save some time when I'm out of the office and at home.
I'll try to be as specific as possible about the specs and problem:
The computer in work is a brand new dell vostro 410 running window Vista, which is plugged into a router using a CAT5. There is also a printer in the office which is also plugged in to the router using a CAT5 cable. Printer works fine from the new dell vostro and internet connection works fine also.
My ISP is 02 in the UK, the router they sent me is all labeled as an 02, but a little research tells me it's just been badged up and its actually a Thomson ST 780WL.
I have setup incoming connections from my work computer and chosen who can connect to the computer adding a username and password, I also checked the box for How will people connect 'through the Internet'. I basically followed the instructions at http://www.onecomputerguy.com/networking/vista_vpn_server.htm
This is where I began to get confused as I also did this too: http://theillustratednetwork.mvps.org/Vista/PPTP/PPTPVPN.html
I'm not in work right now, so I'm a little hazy, but I think I currently have a private newtork called 'NEW NETWORK' which has 'local and Internet access' and I think I have a setup for 'incoming connections'.
I haven't made any changes to the router setup in work, I'm guessing thats where the problem lies, but on entering 192.168.1.1 into my browser I logged into the router panel and there wasn't actually that many options.
My laptop is a dell xps that I connect to my WGT624v3 router using wifi. There seems to be loads more options on this router in the panel. Anyway, my xps laptop runs windows XP and I followed this for setting a VPN connection. The only thing I didn't seem sure about was the Destination address. I assumed this was the ip address of my router at work. 78.86.xx.xxx so I entered this in that field.
OK, so I try to connect using the same username and password which I specified on my work computer for the 'incoming connection' setup. I usually get error code 800. Confused I am, but I actually tried to ping my work router whilst at home and there is no response anyway, so this 800 error is accurate I guess. Even more weird is I can't even ping my own router at home when I'm at home using the external I.P address, I can only ping the 192.168.1.1 (Is that normal?)
When I change the properties of the Type of VPN on my home laptop from Auto to PPTP VPN then I get a different error code: 678 The remote computer did not respond.
I'm hoping someone can setup some step by step instructions for me. I've read a bit about port forwarding etc, so I'm thinking its also to do with this, but I'll wait for some replies before I try anything else.
