I press this script（http://forum.mikrotik.com/t/how-to-mail-me-if-isp-ip-change-pppoe/100611/1 if wan ip change, send e-mail notification, has been working satisfactorily. ip-per-acquisition are xx.xx.xx.2 ~ xx.xx.xx.12, how to make it in a fixed ip, such as xx.xx.xx.10, if not xx.xx.xx.10 , repeatedly dial, get to know xx.xx.xx.10. script can be used to achieve it, I hope to provide ideas. Thank you.
Please forgive my English, it comes from Google Translation.

Why not simply use ip > cloud?

If you have a web or other kind of server behind the mikrotik, you want to be available from outside, just create a CNAME (on your domain DNS) referring to the routerboard xxxxxxxxxx.sn.mynetname.net record.

Thank you pukkita, maybe I did not explain what I mean, I am not for easy access to my rb450g, in order to solve my upnp mapping. Wan ip address changes each time the interface, upnp on the failure, so I hope wan adsl connection interface can be fixed ip. Or is my thinking there is a problem, solve upnp problem, there should be better ways.

What’s the 450G ROS version? firmware version?

That post is almost 10 years old… in addition, there have been lots of uPNP fixes.

rb450g v6.36.2 fireware is 3.24 . The latest version

Try this script. schedule it to run every 5mins. It will check if the ppoe has a new IP and if it does, it will remove the entries for upnp.

:global currentIP;

:local newIP [/ip address get [find interface="ppoe1"] address];

:if ($newIP != $currentIP) do={
    /ip firewall nat remove [find comment~"^upnp.*"];
    :put "ip address $currentIP changed to $newIP";
    :set currentIP $newIP;
}

Be sure to change the interface=ppoe1 to match your ppoe name.

Thanks you ,@2frogs.Nice! it worked. But why not “/ip firewall nat remove [find dst-address = xx.xx.xx.xx]” or “/ip firewall nat remove [find dst-address = $currentIP]”, does not matter, this issue has been resolved. But why not put it to me, you want to get the ip address, it has been dial-up, I want to know the ip address, stop dialing, this purpose is to obtain a static ip address. If so, then you can achieve great.

I carefully observed the ip address range my adsl out (isp) obtained, xx.xx.xx.2 ~ xx.xx.xx.12, how to make adsl out to get the desired ip address, otherwise, have been dialing.
Sincerely hope you can help me solve.

I used the phrase “/ ip firewall nat remove [find comment ~” ^ upnp *. “];” After the wan ip change can delete the old upnp mapping.
