Hi Albert:
Thanks for the fast response and I will join the new mail list.
I understand that you only have support for NAT in xTR but I am under
the impression that an xTR (MN) behind a NAT sends an Info-Request to
a Map-Server to initiate a Info-Reply by the Map Server to establish
the NAT info and a list of RTR's. Is this not correct?
My scenario:
xTR-MN --> NAT --> Info-Request (type 7) --> MSMR Map Server
xTR-MN --> NAT --> Info-Reply (with RTRs) <-- MSMR Map Server
xTR-MN --> NAT --> ECM Data-Map_Reg --> RTR
RTR --> Map_Reg (RTR RLOC) --> MSMR (Map Server on
LISP-BETA)
RTR <-- Map_Notify(RTR RLOC) <-- MSMR (Map Server on
LISP-BETA)
xTR-MN --> NAT --> ECM Data-Map_Reg --> RTR
xTR-MN --> NAT --> ECM Data --> RTR --> DATA OUT (to LISP direct or
legacy via PETR)
xTR-MN --> NAT <-- ECM Data <-- RTR <-- DATA IN (from LISP direct or
legacy via PITR)
The source for the OOR map server receive-message handler as follows
does not support this.
static int
ms_recv_msg(oor_ctrl_dev_t *dev, lbuf_t *msg, uconn_t *uc)
{
int ret = BAD;
lisp_msg_type_e type;
lisp_ms_t *ms;
ms = lisp_ms_cast(dev);
type = lisp_msg_type(msg);
if (type == LISP_ENCAP_CONTROL_TYPE) {
if (lisp_msg_ecm_decap(msg, &uc->rp) != GOOD)
return (BAD);
type = lisp_msg_type(msg);
}
switch(type) {
case LISP_MAP_REQUEST:
ret = ms_recv_map_request(ms, msg, uc);
break;
case LISP_MAP_REGISTER:
ret = ms_recv_map_register(ms, msg, uc);
break;
case LISP_MAP_REPLY:
case LISP_MAP_NOTIFY:
case LISP_INFO_NAT:
OOR_LOG(LDBG_3, "Map-Server: Received control message with
type %d."
" Discarding!", type);

Hi Rod,
We only have support for NAT in xTRs. The support of nat traversal
in Map Servers and RTRs is not yet implemented. Some Cisco boxes
have support for NAT but is not official and have some limitations
(only one xTR behind the same NAT). The RTR implementation of OOR
is only supporting ELPs (Explicit Locator Path). If you are
interested in this functionality and can give you some examples.
On the other hand, would you mind to use the new mailing list
<https://github.com/OpenOverlayRouter/oor/wiki/Mailing-lists>? We
are trying to do a rebrand of the project.
Thanks
Albert

Hi Albert/Others:
While I have had some success (crashes after an approx an hour) I
can't seem to get Lisp-MN behind a NAT sorted out at all. I
assumed the OOR-MSMR could handle the Info-Request and Info-Reply
but it returns a discarding error and inspecting source appears
to not have any implementation
switch(type) {
case LISP_MAP_REQUEST:
ret = ms_recv_map_request(ms, msg, uc);
break;
case LISP_MAP_REGISTER:
ret = ms_recv_map_register(ms, msg, uc);

I also find that implementing a RTR configuration is far from
clear. Do you have any example configurations or tutorials? Or
am I just looking to do something not yet sorted out?
If a NATed MN is possible can you please explain how am I suppose
to get a MSMR that will help me determine the NAT configuration
and work with a RTR list? Does Cisco do it in their IOS version?
Is there an older or forked version of oor or lispmob source I
should be using?
Do you have any further info besides you published papers on the
RTR. I have the slides and whitepaper from the LispMob site.
Regards, Rod,
