Minimal L2TP for testing
Hello.
I want to install minimal configuration of L2TP to connect remote mikrotik to L2TP server on Debian. No IPsec, no pass, just minimal to establish a
connection for a test.
I use apt-get install xl2tpd ppp
The configuration is:
/etc/xl2tp.conf:
[global]
port = 1701
access control = no
[lns default]
ip range = 10.10.10.2-10.10.10.254
local ip = 10.10.1.75
require authentication = no
name = LinuxVPNserver
ppp debug = yes
pppoptfile = /etc/xl2tpd/options.xl2tpd
/etc/xl2tpd/options.xl2tpd:
noccp
auth
mtu 1410
mru 1410
nodefaultroute
proxyarp
silent
debug
ms-dns 8.8.8.8
I use iptables to allow only for an IP all ports to connect.
But connection could not be established. The log says:

On the Mikrotik the logs repeats:
initializing
connecting
terminating
disconnected
Where is my fault. Can someone give me a hint?
