What do you mean by remote? Remote as in on the same LAN or remote as in across the internet.
First off, make sure your firewall on the home computer isn't blocking outside access to subversion.
If you still have problems on the same LAN, then I dont know.
For WAN, you have 3 options
- Configure the router to DMZ to your home computer (forward all ports, the least secure option)
- Configure the router to do a port-forwarding to your home computer to allow outside access
- Configure IPSec or some other VPN type technology. (out of my area of expertise)
Once you have the ports forwarded or whatever configured, then how are you accessing your home computer? You can not use 192.168.* across the internet. You must get your public IP address and connect using it(I recommend http://ipchicken.com ). If your public IP address is dynamic, then you will need to get a dynamic IP address service such as http://no-ip.com so that you can get a free domain name that will always point at your home computer, and then you just use that domain name instead of using your home IP address and it will always work.
