Changeip errors

Greetings !

I am using the script from the wiki http://wiki.mikrotik.com/wiki/Dynamic_D ... angeIP.com
to update a dynamic ip.

The adsl modem is connected in bridge mode through a pppoe interface

The script seems to be working (from what i can see at the logs) but the call to / tools dns-update ends up with an error in logs
ddns error timeout

I even used the dns-update command from a terminal window, passing the info manually but still i get the same error

Using the windows client from a machine on the local net the ip gets updated correctly


Any idea what could be going wrong ?

To answer my own question :)

After a bit of sniffing i found that for dns-update to work correcltly port 443 needs to be open, or the replies from changeip never get back

Yes, dns-update uses SSL to protect your credentials. If you are using established / related rules the response should be allowed back in automatically. Since this traffic originates from the router it should be using the output chain to start the conversation.

Can someone provide the Chain to allow port 443 so i can add it to my firewall filter.. I have tried but i seem to be doing it incorrectly... everything works fine im just getting a connect error, and i have firewall disabled... -Jordan
