Hi Nicolas,
Sometime last week, the VPS that hosts our streisand instance went down. During that time, the network still had internet access and fell back to my local ISP's IP address. My understanding was that internet would be cut off the the VPN wasn't accessible. Any ideas?

My speed test results are below and might be interesting to others anyways.
Thanks,
Marvin

The tests also made me realize something weird is going on where I'm unable to connect directly to the lime node which is also the only node with internet access. I have to restart the router whenever I re-enter the network.

Can I ask you out of curiosity what speed:1] your pure ISP connection is2] your vpn is delivering3] you get from a device connected to a non-exit node [so not the one connected to the hex]?I’m having real problems getting steady speeds out of LiMe in general, and really high latencies, compared to OLSR which always delivers, although not very fast.Thank you

1 alone didn't fix it. 1+2 did. Switching MTU from 1280 to 1350 immediately resolved the issue.
So I think it's all set now. I have three lime nodes forming a mesh around my house. One of the lime nodes is connected over ethernet to the hex.
I'll report back any issues and successes. Now that this is working, we'll start setting up more clusters, all using the same exit node. I suppose we'll eventually want to figure out how to connect using a lime node only without a hex. I don't think it will be cost effective to have a hex at every node that connects to the Internet. We almost had that working before.

See the last part of this video and follow just the DNS settings part: https://www.youtube.com/watch?v=SW6AZ33go5U [this is the video I followed for my howto in the first place with the exception of a few things such as L2TP instead of PPTP of course.In the second case, your MTU might be wrong. Have you followed the MTU section of my video? If not [likely you made the right choice as mine was a simple empirical one-time experience] why not? Have you set it to 1350 or have you left it default? See this link for a packet fragmentation ping test guide: http://www.tp-link.com/us/FAQ-190.html.Let me know how it works out

That's weird. Sending that last email worked even though I am still connected via ethernet. Websites still won't load.

- hex: out the fourth port <ethernet> into computer
In any event, it looks like your computer is hard-set [meaning in system options or via ifconfig/ipconfig] to use itself as the DNS server [strange config btw, is this a server?] when using the wifi interface [127.0.0.1] whereas it’s not hard-set to a specific DNS server when using the wired interface.
Its Ubuntu 16.04 x64. I use a lot of virtualization (virtualbox, lxc) so the bare-metal I'm running from should be fairly close to a stock ubuntu install.

Hey, I'm replying with two sets of commands. The first is always using WIFI which is working fine. The second is connecting my computer to the hex via ethernet, which does not work well.
I'm pretty sure its not my computer's ethernet. I've also tried connecting my computer directly into the isp router via ethernet and that works fine.
