Hey Nicolas, I tried sending you this email directly, but it bounced
back. I can't tell if your domain thinks mine is spam, or vice-versa.
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.

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.

New subject: [lime-users] VPN
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?

New subject: [lime-users] VPN
Hi Marvin
Sorry for the very late reply.
You’re right, we’re able to reproduce the issue on routers configured as per our
tutorial.
However, we have a previously configured router that does not fall back to ISP directly,
which is why we were saying there is no fallback in the howto.
I’m trying to find the first tutorial we had followed back in the day to set up the
killswitch.
Sorry we didn’t test this more thoroughly on the config we are suggesting in our tutorial.
I’m trying to find the differences between the two webfigs, but can’t find any for now, or
nothing I could reproduce anyway.
I’ll keep you posted. Thanks for pointing this out.

I've also tried connecting my computer directly into the isp router via ethernet and
that works fine.

New subject: [lime-users] VPN
Hey, have you ever tried the same setup with the VPN client on a TP-Link
TL-R600VPN? I'm giving it a go now, and the menu options are a little
confusing.

Hi Marvin
Sorry for the very late reply.
You’re right, we’re able to reproduce the issue on routers configured
as per our tutorial.
However, we have a previously configured router that does /not/ fall
back to ISP directly, which is why we were saying there is no fallback
in the howto.
I’m trying to find the first tutorial we had followed back in the day
to set up the killswitch.
Sorry we didn’t test this more thoroughly on the config we are
suggesting in our tutorial. I’m trying to find the differences between
the two webfigs, but can’t find any for now, or nothing I could
reproduce anyway.
I’ll keep you posted. Thanks for pointing this out.
