Hi I have a home network set up with an OpenBSD gateway which is bridged to an ADSL router, two Windows XP machines and assortment of old boxes I play around with, and a few IP's available to me. What I want is remote access back to my windows boxes probably using VNC, and to be able to ssh to my gateway and into my network. At least one of the sites I wish to connect from uses a web proxy and I would have to tunnel through it.
What software/techniques can people suggest, and how much of a risk am I exposing myself to by doing this? I have survived this far without it, but it would be nice to have. Can I do it without it showing up in a port scan? Now to the pf question. My policy for everything blocked from entering the network is that it is dropped with no reply. I have several ports forwarded to my Windows box, mainly for file sharing over IRC so they are only open when I wish to do a DCC send. I would like to drop error messages coming from my windows box when those ports are closed so no one got curious as to why those ports replied and nothing else did. As I allow everying exiting the network to keep state, how would I block these packets? I know it probably doesn't get me much in the way of security, but it is an interesting problem. Any suggestions? Any suggestions would be greatly appreciated. Regards, Kim
