No MAP Register with 1.3.0 with NAT traversal on #42
Description
Hi,
my testbed looks like the following:
- 3 Debian 10 Servers (MS, xTR, RTR) - all with public routeable RLOC
- 2 OpenWRT boxes configured as xTR - 1 with public routable RLOC, 1 with NAT
- EID space are some RFC1918 networks
On the debian servers "master" was self-compiled, for OpenWRT i used the precompiled package from http://www.openoverlayrouter.org/downloads/OpenWrt/
Communication works fine between the EID spaces, except for the OpenWRT box behind NAT which is unable to map-register. According to log output it sends out map-register packets, which don't show up on a tcpdump, which means they never actually get sent.
A downgrade of oor on the OpenWRT box to version 1.2.1 fixed this, map register over RTR is successful and EID space is reachable by others.
