Problems with my VPN

[lrdefender]

Hello to all

I´m not expert with networks but i have a network in my job, with 5 machines with windows xp pro sp2. My network use a workgroup (not domain) and i use a a range of IP like 200.200.xxx.xxx on 255.255.xxx.xxx. My server VPN use a ADSL modem with dynamic IP.
In my house i have a windows xp sp2 with a cable modem. I need to have dynamic IP because my cable ISP provider. I can connect to my server in my job but i can´t see any machines on my windows explorer. I try to remove the firewalls, but is the same problem.

I need to know some informations ( i read a lot of foruns and make a big confusion):
- In my home, i need to configure my machine with the same range of IP i have on my network job? If i do that, i loose the internet cable.
- I have a partition on my HDD Server and i try to use "\\pcf\c" but i can´t see the partition? Why?
Thanks for your help
Carlos

1. If they are on a different workgroup there is no guarantee that it will work properly.
2. Some firewalls block NetBIOS traffic over VPN connections.
3. C:\ is a hidden volume so to map it you have to use \\Computer-A\C$.

1.Do not use the same IP range as the one at work otherwise your home PC will get confused as where the traffic should go. Say you have 192.168.10.0/24 at work, use something like 192.168.20.0/24 at home.
2.If you still can't access the server by the name, try it w/ IP instead. That happens when you don't have DNS set up.

You are using an ilegal ip range if you are using 200.200.x.x, there are 3 ranges you can legally use for internal networks;

10.x.x.x (10.0.0.0/8)
172.16.x.x - 172.31.x.x (172.16.0.0/12)
192.168.x.x - 192.168.255.255 (192.168.0.0/16)

I believe it was brought up in RFC1918. If you dont use a range in these allowed ip ranges then it messes up routing.

Hello

I try to use C$ and use a IP range near my IP , but i can´t see my network.

Im my job, i have a server with Unix with a software to manage all the company. The server have a IP on the range 200x200xxxxx. All the others computers have windows XP and 98, but they need to access this software on the server with a little software who need to redirect for 200x200xxxx.
I think i must configure all the network with this range of IP. It´s correct? Can I configure al the network with dynamic IP and teel the software to use a IP range 200x200xxx? I´m not sure, but i think this is impossible.

I don´t know nothing about legally IP range, can anyone tellme where can i read more about this?

Thankyou very mutch

What Thriemus said:
10.x.x.x (10.0.0.0/8)
172.16.x.x - 172.31.x.x (172.16.0.0/12)
192.168.x.x - 192.168.255.255 (192.168.0.0/16)

That's it. If that's not enough - you're on your own. Use whatever block of IP's suits your fancy (from the above options).

If you're talking about the server having a real pingable public IP of 200.200.x.x -- unless you're in Brazil - that's not likely a real public IP.

Now, that being said - you CAN make non-private IP's work in a LAN, but don't expect to get to that REAL outside IP outside your network.

If you can, change your LAN subnet. Then we can work with it.
