If you need to access your home network (but it can be your work network aswell) from a remote location, a great option is to set up some sort of VPN connection. There are a few different types of VPN connections, such as PPTP, L2TP, and IPSec, and each has advantages and disadvantages. One of the advantages of PPTP VPN connections is that almost all devices that can create VPN connections, have a PPTP VPN client already.
Linux can be set up as a PPTP Server easily ... here is how to configure a pptp server on Ubuntu:
VPN pptpd SERVERShare on Twitter Share on Facebook
-enable port forwarding on router : port 1723
# install pptp
sudo apt-get install pptpd telnet iptables
# edit pptp
sudo nano /etc/pptpd.conf
localip <local_ip>
remoteip <remote_ip start - end>
# edit pptp options
sudo nano /etc/ppp/pptpd-options
noauth
refuse-pap
refuse-chap
refuse-mschap
require-mschap-v2
require-mppe-128
nomppe-stateful ## MPPE should be stateless
proxyarp
nodefaultroute
lock
nobsdcomp
noaccomp
noipx ## you don't need IPX
mtu 1490 ## may help your linux client from disconnecting
mru 1490 ## may help your linux client from disconnecting
lcp-echo-failure 3
lcp-echo-interval 60
# edit users
sudo nano /etc/ppp/chap-secrets
# ipp masquerading
sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
or
sudo iptables -t nat -A POSTROUTING -s <local_nw> -o eth0 -j MASQUERADE
# allow port 1723 and protocol 47
sudo iptables --append INPUT --protocol 47 --jump ACCEPT
sudo iptables --append INPUT --protocol tcp --match tcp --destination-port 1723 --jump ACCEPT
# ip forwarding
sudo sysctl net.ipv4.ip_forward=1
or
sudo nano /etc/sysctl.conf
net.ipv4.ip_forward=1
in /etc/default/ufw change the DEFAULT_FORWARD_POLICY to “ACCEPT”
# restart pptp
sudo /etc/init.d/pptpd restart
# troubleshoot - see logs
sudo tail -f /var/log/syslog

I had some issues with django/mezzanine gallery app and the utf-8 encoding. Now that I found the solution debug should be off. I'll post the solution on the blog soon. Anyway, thanks for pointing out this to me.
