That’s so stupid and explorative thing!

The easy and fast workaround comes in four steps:

1. Configure a free dynamic dns service in your router
2. Buy a cheap with 2 static IPs VPS service (I use siterack.net). Configure DNS properly with bind or CPanel.
3. Setup crontab to run a proxy script every 30 seconds (append to /etc/crontab):
   * * * * * root webproxy.sh
   * * * * * root sleep 30; webproxy.sh
4. Put webproxy.sh with execution permission bit in your PATH (change 84 to your webserver port and add an authorized key to your home server)
   #!/bin/bash
netstat -tan | grep LISTEN | grep 80
if [ "$?" -ne "0" ]; then
        ssh -f -L *:80:*:84 user@yourdynamicdnsaddress sleep 999d
fi

Good luck
