My work network (like many) is quite locked down, so what I did was create a PPTP VPN on my home router. Works great........for a while until the lease on my IP expires....how can I get around that?
I don't think you can. I would suggest that you set your DHCP server to give out the same ip for an indefinite amount of time or set it up so the DHCP server always gives you the same ip every time the lease is up.
