The pptp-phone is me accessing the network, but then all the time I get entrys like the last 3 entrys on the log. Is this just people trying to access my router or hitting it?? The IP’s from where I connect to this router remotely change often, but how do I prevent these TCP connections that arent mine?? Do you think they’ve gained access???

No, they didn’t gained access (yet, rsrs). It’s a PPTP try or a scan on port 1723, but read Normis’ post, where he tells about basic security:
