Hello. I have RB750 device.
Help me please config this device to connect to internet.
My provider have l2tp server for autorization.
All config by default.
Cable linked to ether1.
10.139.152.1 - gate ISP, who connect to ether1. Takes by DHCP
83.102.255.43 - ISP L2TP server for autorization
I Make l2tp-out1 interface - l2tp client
I Make route to 83.102.255.43 through 10.139.152.1
I Make route to IP_DNS through 10.139.152.1
DNS resolved and l2tp-out1 connected.
What I did not do the default gateway (and the interface l2tp-out1 and 83.102.255.43 ), ping is not run.
What could be wrong? 
I noticed that then l2tp-out1 establishes a connection then l2tp server 83.102.255.43 stops a ping.
P.S. Sorry for bad English.
