Hi Matt,
I'm happy you can finally make it works.
I think that the problem you have is that the DNS you are using is
configured to only reply to some range of IPs. Your DNS is receiving the
query from the proxy-etr and rejecting it as the source IP address is
not from its domain. You can try to use the DNS from google (8.8.8.8)
which doesn't have this limitation.
Regarding Wireshark capture, in the main screen, it only appears a
summary of the packet. If you expand the packet, you will see that the
external header has the correct values. You can also apply the wireshark
filter "lisp" for control packets and "lisp-data" for encapsulated data
packets.
Regards
Albert L.
PS: If you don't main, I will also add you to the announcements mailing
list in order you receive a notification for new releases of the software.

Hi,
First of all, thanks for your help !
I've passed my modem into bridging mode and disabled its dhcp. It has
turned off its firewall( i checked the modem configuration, iptables
etc... it is a brand new DSL320B
http://www.dlink.com/uk/en/home-solutions/connect/modems-and-gateways/dsl-320b-adsl-2-ethernet-modem).
I run ubuntu which has no default fw either
.teto@tatooine:~$ sudo iptables --list
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
To sum up the current configuration, my ubuntu connects via pppoe to
my modem which converts that connection into pppoa to France Telecom
device with IP 193.253.160.3 (I guess that would be the BAS ?).
Without running LISPmob, ppp0 is assigned my public IP address,
physicall everything is sent to eth0:
teto@tatooine:~$ ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

inet 82.121.101.237 netmask 255.255.255.255 destination 193.253.160.3
I now receive map-notify and map-reply answers:
: OUTPUT: Orig src: 82.121.101.237 | Orig dst: 195.50.116.18
DEBUG-3: Fordwarding native for destination 195.50.116.18

DEBUG-2: Received a LISP control message
DEBUG: Received a LISP Map-Notify message
DEBUG: Map-Notify message confirms correct registration
DEBUG-2: Completed processing of LISP control message
and I can use LISP but without DNS: DNS requests recieve no answer.
For instance I could surf the lisp4.net page or even gmail as long as
their I think the problem is because my DNS requests don't get
encapsulated by LISPmob (cf screenshot of capturing eth0, the physical
interface by which every packet passes): the underlined packet asks my
dns resolver 80.10.246.1 from my EID (153.16.149.112), shouldn't it be
encapsulated by my itr (82.121.101.237) to go to a petr ?
Here is the ifconfig with LISPmob enabled

lig sends requests via eth0 ( address 192.168.1.45) even though I did
lig -m 195.50.116.18 -s 82.121.101.237 132.227.86.4 so it isn't a
good test.

Hi Matthieu,
We see that you got neither Map-Reply, nor Map-Notify. Please, make sure
that you are not behind a firewall.
You should be able to check the Map-Resolver (to see if you can get any
Map-Reply, regardless of LISPmob) with the lig tool.
Regarding your PETR question, at this point LISPmob chooses the first valid
PETR from the config file. Improvements on PETR selection are expected in
future releases.
Please, get back to us once you check if there is a firewall affecting
LISPmob.

When I try to surf through the internet though it doesn't work, I can
see map-requests but don't see map-reply (cf enclosed picture of

For instance I send a map request to know the rloc to which
