|In the past, I have been able to access several services at my office using the office's static WAN IP address (let's call it aa.bb.cc.dd). For example, I have a server that runs a VPN (aa.bcc.cc.dd:4444), FTP (aa.bcc.cc.dd:21), and remote desktop (aa.bcc.cc.dd:3389). I've also been able to access the office router's configuration page (aa.bb.cc.dd:8080). |
Recently, my laptop fails to connect to any of the services or the router from outside the network. At first I suspected my home internet connection, but I tested 2 other computers on my home network, and they have no trouble connecting to the office. I have also taken my laptop to a different internet connection, but I cannot connect to any of the services. I am able to ping the address from my laptop. However, when I run a tracert, it returns only one hop. Running a tracert on the other computers at home result in at least 13 hops.
The bottom line is that my laptop on any internet connection seems to be blocking this specific IP address. I have several customers who run FTP and remote desktop services, and I can connect to those via their IP from my laptop without trouble. So the problem centers on my office's WAN IP.
On my laptop, MS firewall is shut down, and I am running no 3rd party firewalls, there are no errant IPs in my hosts file, and I've run full virus and malware scans which turn up nothing. There are no blocked IPs or sites in my Internet security settings. I am completely stumped. Can anyone give me a clue?
