L2TP Encryption Question

RouterOS General

Hi guys,

I have a quick question about L2TP VPN.

Basically, I have setup a site-to-site VPN using L2TP on two Mikrotik Routers. I’m only using the basic L2TP which uses port 1701 UDP.

If I do not configure IpSec on this L2TP link, would the data sent over this VPN encrypted?

Thanks in advance.

L2TP has no encryption by itself.

Thanks, I suspected that would be the case.

I will change my L2TP VPN to use SSTP instead.

Thank you!

Or run it over IPSec.

I have a dynamic IP at one end, would be easier to just switch it to SSTP. :slight_smile:

Up to you… the other option is to use a script to update it. I personally am running EoIP/IPIP/GRE tunnels with dynamic Ips on both sides. But SSTP works. I posted the script into the scripting forum if you want it.

Thanks, I think I managed to find your post.

I’ll have a look and see if I can adapt it to my needs.

Thanks again!

No problem. It’s a pretty general script. Let me know if you run into problems.
