<div>Had this myself once - good to rule out:</div>
<div>Contact your ISP and ask them what your fixed IP is (presuming you are paying for a fixed IP?) and enquire if they are doing any maintenance or future scheduled work on their infrastructure that may affect their addressing scheme.

<br>onto my router and through to the RoR box. when i go to<br><a href="http://www.whatisimyip.net">www.whatisimyip.net</a> i get a totally different IP from the one my router<br>says it has??? how is that possible? i restarted my router and the it
<br>gets a new IP but the whatismyip is still different.<br><br>i have the router set up to forward any tcp for port 3000 onto the<br>particular box. i also have the remote management switched on - its just<br>one of those consumer netgear things. that should allow me to access
<br>remotely the router set up. it's set up for port 8080.<br><br>ok, so when i go to access the router from the internet onthat port i<br>get nothing. however i tried out neels suggesion and used nmap. that<br>told me ports 80 and 5190 are open. it says 3000 and 8080 are closed.
<br>my router is set up that 3000 and 8080 should be open????? also, 80 and<br>5190 closed??? what is going on? for nmap i used the IP address the<br>router tells me it has.<br><br>the router has a log, all that is showing is that i constantly get
<br>attempts made on port 26390? (Dos) whatever that means? does that mean<br>denial of service? quick though came to me...does that prevent access<br>from outside? is that my problem?<br><br>any help appreciated? this problem is more than a bit annoying now :-)
