Question : Ubuntu svn: Network connection closed unexpectedly

Hi earlier today i set up a svn at another network with my laptop.
Then i came home and i was hoping to use it at my home network as well.
So i open up the ssh port 22 and the svn port 3690 in my firewall and i use this shell script
 #!/bin/sh
svn checkout svn+ssh://[email protected]k.ip.number/home/svn/project
but all i get is Network connection closed unexpectedly.
I can ssh my ip and i have restarted my network card also my router.
is there something i have forgotten?
if i am using the local ip 192.168.0.xxx it works, so it has to be some problem with the firewall?
Thank you

Answer : Ubuntu svn: Network connection closed unexpectedly

i solved it it was my ssh keys that was set to the other network ip, i just had to delete the ~.ssh/ folder
