Dear Teto,

I think that the problem is that you don't have defined a default gateway for interface eth1. LISPmob needs to have a default gateway for each interface with locators. You could define them with different metrics.
I hope this will solve your problem. Please let us know the result.

Best regards

Hi,

Still me having problems sorry. I try to download files to my laptop
(153.16.49.112/29) from a server, (153.16.49.120/29) both running lisp
0.3.2. The weird thing is sometimes it works sometimes it doesn't even
though I don't touch any configuration or lispmob within.

You can find a screenshot of my desktop here
http://uppix.com/f-lispmob51b0644b001308d5.png (thought it was the
best way to sum up all informations):.

On the right hand side ( blue square) you have my laptop terminals:
4: output of $ lispd | grep 153.16.49.120
5: output of $ tshark -i eth0 -R "tcp.port == 8000"
6: trying to download file from my server via wget. Just by reentering
that command several times, without touching anything else, I get
different results without being able to identify the culprit.

On the left hand side, there are the server terminals. This server is
multihomed with eth0 and eth1.
1: lispmob output
2: output of tshark -R "tcp.port == 8000" -i eth0 -i eth1
3: output of tshark -R "tcp.port == 8000" -i lispTun0

pings between server and laptop always succeed. There is no iptable
rules in either case. What I wanted to show with this screenshot is
that between 3 and 2 we seem to lose the syn/Ack packets (once more
not always, only from time to time, on the screenshot it's the case) ,
visible by tshark on lispTun0 but not on either eth0 or eth1. The
server uses an unmodified lispmob version.

I was wondering if you had any idea where that could come from ?
I will be idling on IRC this afternoon.
