Dear Anas,
The current implementation of LISPmob requires that the host has a
publicly routable RLOC, which is neither firewalled, nor behind NAT. The
encapsulated or data packets you are sending are using the private
address as RLOC. As a consequence of this, other nodes doesn't know how
to reach your pc.
Regarding the Encapsulated Map Request that you see, they are probably
generated by your operation system or applications you have installed.
Once LISPmob is running, the routing table is modified to all packets go
through the lisptun0 interface. If no map cache entry is found for this
entry, an encapsulated map request is generated. As you don't receive
the map replay due to the private address of the RLOC, this encapsulated
map request are continuously generated as long new packets are received
in the lisp tun interface.
Regards
Albert

Hello everybody,
I am currently working on LISP and trying to implement it using the
LISPmob solution.
I am actually facing some problems and would be very happy if someone
could help me resolving them.
My configuration :
• I am using the following EID : 153.16.254.1/32
• my RLOC : 172.20.10.4 (since i am connected to the internet at home
and this is the private address assigned by my router OR shall i use
its address ? )
• the mapping system (Map server - Map resolver) : 217.8.98.46
(retrieved from http://www.lisp4.net/images/lisp-ddt.pdf)
The problems noticed :
• I can see a map register with my EID towards the map server when
LISPmob starts.
• Then immediately, there are several Encapsulated Map Request sent to
those addresses 62.201.129.203 and 62.201.129.201 ( although i am not
sending anything to them at all ! )
Please find below the configuration file lispd.conf and the logs, and
attached a wireshark capture of the traffic i am seeing on my wireless
interface.
Best regards,
Anas ZAKKI
