You could ssh and do a script (run by cron) that proxies the modem http 
access to the ssh port after disabling the ssh service.  A second  
script  set by cron to run  some time  later  then  removes  the proxy  
and restarts ssh  daemon.


You can't have two services on the same port.

Between the  two times  usining you r laptop  web browser to your public 
IP on ssh port will actually access modem on it's port (useually 80)

so on italy laptop http://myhomeip:22  during time proxy is running on 
server will really access the LAN side of home modem.

I have no idea really how to use cron or set up a proxy as described  in 
Linux (though I have used NT's AT comand and used Wingate as proxy), but 
I'm 100%  sure this will work and loads of folks here would advise on 
script exact contents..

If  you had had VNC rather than ssh you could have seen firefox. Running 
lynx text based browser will work over ssh, but it would be useless for 
web config of most Modems / Firewall /routers I know.
