Changed to ChangeIP but need to keep Dyndns name!

RouterOS General
1

Hi

I have got the changeip script working, so all good. however i now need to keep my dyndns name, as to many clients are already configured for that name. Im not running http services, so i need all ports to be directly redirected. Any ideas?

Also, is it possible to mod the script to work with a specific pppoe connection, my MT needs to dial 4

Thanks
Mark

you can update your dyndns hostname to become a cname of the changeip one. that way it is just an alias.

we can modify that script to work on a particular interface specifically… email us directly and we will work with you to get what you need. support at changeip dot com.

Are you saying that you can modify this so that it will update the address of an interface that I specify? I am using ECMP routing on 2 PPPoE connections. One is static and has dns set for it. The 2nd connection changes anytime the interface drops. I would like to setup a changip host and have the script update the host with the DHCP address from the 2nd wan link.

Use this script;

:global ddnsuser "your_account_name"
:global ddnspass "your_account_password"
:global ddnshost "your_changeip_ddns_name"
:global ddnsip
:global ddnslastip [:tostr [:resolve $ddnshost] ]
:if ([ :typeof $ddnslastip ] = nil ) do={ :global ddnslastip "0" }
:global ddnsinterface "your_mikrotik_interface_name"
:global ddnssystem ("mt-" . [/system package get system version] )

:local int

:local ddnsipfn [ /ip address get [/ip address find interface=$ddnsinterface ] address ]
:global ddnsip [:pick $ddnsipfn 0 [:find $ddnsipfn "/"]]

:if ([ :typeof $ddnsip ] = nil ) do={
:log info ("DDNS: No ip address present on " . $ddnsinterface . ", please check.")
} else={

:if ($ddnsip != $ddnslastip) do={

:log info "DDNS: Sending UPDATE!"
:log info [ :put [/tool dns-update name=$ddnshost address=$ddnsip key-name=$ddnsuser key=$ddnspass ] ]
:global ddnslastip $ddnsip

} else={
:log info "DDNS: No update required."
}

}
