Hi,
I want to connect my home and office computers(atleast share files, full TCP/IP would be best). But the problem is both computers have invalid IPs 172.16.x.x and I do not have control over gateways to setup VPN(one on in2 cable network, other on star cable network). I can keep both computers on 24 hrs, having access to internet via their local gateways. But I do not know how they will find each other.
Currently I manually email and download files but is there a way I can actually FTP to and fro?

The invalid IP range will not be a problem. Just ensure that they are in different subnets. At least one of the systems will need a static IP address. Run the VPN server on this system. The other system will act as a client.

I would recommend scp actually, but you need the VPN first.

Probably Amish has a setup like this -
+---------+ +----------+ +---------+ +-------+ | Home PC |----| Cable GW |---<> Internet <>--| Off. GW |--|Off. PC| +---------+ +----------+ +---------+ +-------+
1. Since both the PCs are on private subnets, even if we managed to route the packets from the home PC to the office gateway, the office gateway will reject the packets bound for its private subnet because they are initiated from an external host. (This is if a firewall has been configured properly). 2. IPSEC won't work because the Cable GW does natting on the packets originating from the Home PC. And there is not control over the cable GW. 3. We can connect to the Office PC with a PPTP connection, but it will need a VPN service on the Office GW.
In any case, you'll atleast need a VPN server on your Office GW.

He can't do even an ssh/scp without his admin's grace. So Amish, try maskaoing your admin. (That'll not help much if he is a good admin)

Correct. That is why a VPN is needed. A VPN is an IPSEC tunnel over IP. This means that the RFC 1918 packet is encapsulated in a valid public IP packet, which the gateway will accept and the VPN server on the gateway will deal with.
- IPSEC won't work because the Cable GW does natting on the packets
originating from the Home PC. And there is not control over the cable GW.
BTW, according to the original mail, both PCs are behind a cable modem from the same provider.
- We can connect to the Office PC with a PPTP connection, but it will
need a VPN service on the Office GW.
In any case, you'll atleast need a VPN server on your Office GW.
Without a proper diagram of the logical setup, it is hard to guess exactly what is needed. <snip>

1 that comes to my mind is the 1 from BPB Firewalling using Ipchains for approx 300/-.
The issue is that Ipchains on linux only addressed the network layer of firewalling......application layer nd uer level firewallin cant b achieved........with the available tools.....
