How about someone addressing a packet to your RFC-address and source routing it via your official IP (see the IP options on this)? This will deliver the packet to your router and this machine knows how to get to your workstation or LAN server.
Hi, the routing PC is configured not to forward 192.168.xxx.xxx packets sent from the internet. I know what kind of "experts" work at my ISP! (btw. it seems that here in Austria as well as in the Netherlands CableTV providers have the worst personnel compared to other ISPs, is that true for other countries?) So from what I understood, the only possibility left for an intruder was to "hook" himself to an established connection of one of the workstations to the internet. if so, how could he do this, and what possible actions can I take? thanks mike
