Ask your company if they will pay for an DSL service upgrade to one with a static IP.... then you can have your very own VPN and do things properly !
P.S. Just noticed it's you XV105...... so how about making a VPN your next pet project...
Don't tempt me!
Seriously, I already have a dyndns account but unfortunately company policy is (a) that they will pay for domestic ADSL and (b) mandatory use only of Cisco VPN and associated company-supplied certificates.
