What tunnel can be setup with 1 dynamic IP

RouterOS General
1

I have two MT routers connected to the Internet.
One gets a public fixed IP
the other has just a dynamic IP from an ADSL connection

I would like to bring an IPIP tunnel up, but when the ADSL change the IP it gets broken.

What option I have to make a tunnel between the two routers that survive the dynamic IP change at one end ?
Does I need to use IPsec ?

Thanks,

Alexander

I would use l2tp server / client. Server side is the fixed IP. The dynamic client can always dial the server on its fixed hostname. l2tp is the best security vs easiest / most flexible setup.

You can also write some scripts to update tunnel endpoints and use our dynamic dns with it.

Thanks for the l2tp hint, I’ll try it.
I just thougth that encryption gets to much overhead, but bill compare it.

How do I setup dynamic dns in MT router ?
I couldn’t find how to update a public ddns server directly from MT and keep it updated when IP change.

Thanks,

Alex
