I have a DSL connection to my ISP that forces reconnect every 24hrs and the ipv4 WAN address changes.
I’m updating my DNS and tunnel IPs with a script that is triggered by netwatch.
Sadly i simply can’t get it to always work like that.
I have netwatch configured to ping a known outside IP every 2 seconds with 1000ms timeout.
The reconnect itself happens almost instantly (<1s) so sometimes netwatch can’t even see the up/down change in order to execute the script.
I could set netwatch to ping every second… but that could get me banned from the server/ip i ping.
Any other solution?
If only i could set pppoe-client to wait a few seconds after disconnect to connect again, that would definitely solve it.
(I have a backup scheduler event that checks IP change ever hour just so if netwatch fails… but that’s not it either)
This is a scrip i got probably from the Mikrotik WIKI, there was also some ideas and scripts for DDNS. I run a schedule ever 5 minutes that execute this script. If ip changed it updates DNS if not does nothing. Works perfect for me, maybe it will help u?
