Yesterday 5/27/2015 i enabled remote access to my fios router. I have the external ip to my router. I used a vpn that is installed in my laptop to test it out. and it worked from the outside. I could get to the router admin page. I did all this while at home.
Now i'm at work, using the same vpn and when i type in the router ip address, it says not available. i called my wife and she said the the router is on. What could be wrong?
why will it i have access to the admin page using a vpn and then come to work use the same vpn, type the ip and now it doesn't work? do i have to put a 
ort_number at the end of the external ip? is so i'm screwed because i forgot the port number. please help.
thanks
