The following script should be created when you wish to update your ChangeIP.com Dynamic DNS account. Once created you should schedule this to run once in a while. The :global variables should be edited to include your unique username and password, interface name, etc.
:log info "DDNS: Begin"
:global ddns-user "YOURUSERID"
:global ddns-pass "YOURPASSWORD"
:global ddns-host "*1"
:global ddns-interface "EXACTINTERFACENAME"
:global ddns-ip [ /ip address get [/ip address find interface=$ddns-interface] address ]
:if ([ :typeof $ddns-lastip ] = nil ) do={ :global ddns-lastip 0.0.0.0/0 }
:if ([ :typeof $ddns-ip ] = nil ) do={
:log info ("DDNS: No ip address present on " . $ddns-interface . ", please check.")
} else={
:if ($ddns-ip != $ddns-lastip) do={
:log info "DDNS: Sending UPDATE!"
:log info [ /tool dns-update name=$ddns-host address=[:pick $ddns-ip 0 [:find $ddns-ip "/"] ] key-name=$ddns-user key=$ddns-pass ]
:global ddns-lastip $ddns-ip
} else={
:log info "DDNS: No change"
}
}
:log info "DDNS: End"
An updated script here (10/18/07) should allow auto-detection of the default gateways interface name. This script below can be used if you have more than 1 WAN connection, but only 1 is active at a time.
:global ddnsuser "YOURUSERID"
:global ddnspass "YOURPASSWORD"
:global ddnshost "YOUR.HOST.NAME.HERE"
#:global ddnsinterface "1-coxBiz"
:global ddnssystem ("mt-" . [/system package get [/system package find name=system] version] )
:foreach int in=[/ip route find dst-address=0.0.0.0/0 active=yes ] do={
:if ([:typeof [/ip route get $int routing-mark ]] = nothing ) do={
:global ddnsinterface [/ip route get $int interface]
}
}
:global ddnsip [ /ip address get [/ip address find interface=$ddnsinterface] address ]
:if ([ :typeof $ddnslastip ] = nil ) do={ :global ddnslastip 0.0.0.0/0 }
: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=[:pick $ddnsip 0 [:find $ddnsip "/"] ] key-name=$ddnsuser key=$ddnspass ] ]
:global ddnslastip $ddnsip
