When plugged in it will show up as a new interface called lte1 and should be allocated an IP address via DHCP.
On the '''PPP''' page and '''Interfaces''' tab again click on the '''Add New''' button. This time select the '''L2TP Client''' option. Change the name to "l2tp-aa", in the '''Connect To''' field enter "90.155.53.19" which is A&A's L2TP endpoint, again for the username and password you should use the same credentials as for the PPPoE interface used earlier. Be sure to reduce the Max MTU and Max MRU to at least 1460 (And possibly as far as 1340 if on the 3 network)
For the '''L2TP Protocol Version''' ensure "l2tpv2" is selected.
* '''Name''' ''start-l2tp''
* '''Source'''
/interface/l2tp-client/enable [find name="l2tp-aa"]
''
And then
* '''Name''' ''stop-l2tp''
* '''Source'''
/interface/l2tp-client/disable [find name="l2tp-aa"]
:delay 2s;
/ipv6/dhcp-client renew pppoe-out1
''
Finally we setup a Netwatch event to trigger the scripts.
Set
* '''Host'''
* '''Type''' ''simple''
* '''On Up''' ''stop-l2tp''
This will ping ''8.8.4.4'' every 10 seconds and if it fails to get a response will run ''start-l2tp'' and when pings succeed again it will run ''stop-l2tp''.
