I'm trying to connect from work to my router at home, I think I'm getting block some how. however I found an open wireless network and was able to connect fine with the same settings. Here are my setting: my router is buffalo WHZ-HP-G300NH running dd-wrt firmware. I enable ssh on my router port 22 and I setup putty on port 443 on my router I have the remote port also set setup port 443. I'm using cable at home and again this settings work on open networks but not at work. The reason I know it works was because I did a test on whatsmyip.org before and after I connected to my router and the browser displayed my public IP when I was connected. My ip does not change unless I reboot my cable modem so far has not change. when I connect from work a get a connection time out. I think a software on my work laptop is blocking me. I did a netstat and port 443 is listening. I think this may have something to do with the proxy over here at work.
