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 ....
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.
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.
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.
One of them needs a static IP address,
Currently I manually email and download files but is there a way I can actually FTP to and fro?
I would recommend scp actually, but you need the VPN first. Devdas Bhagat
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)
