Hi , can i make 2 PPP VPNs (L2TP) from 2 different WAN ? For ex. LTE + WAN1 , One tunnel connect from LTE , second one from WAN. Dst. Addr both tunnels are the same.

I see no problem in here …

Dst. Addr both tunnels are the same.
… this might trigger a routing problem, because your tunnel-client-ip is either reachable over LTE OR over WAN
.
if this should be something like a redundancy-configuration, … then setup each tunnel with only one interface activ, setup weighted routes. dun !
Maybe you see a glitch, when your main interface goes down … don’t know how hot the soup is your’e cook’in there ?!
.
or you terminate your L2TP-service on a loopback-interface [ in ROS a bridge-interface is (ab)used for the job ] and make this loopback-interface accessible per destination-nat from both: LTE and WAN.
.
then you have to work-around the routing-problem with a policy-route or something similiar to have both tunnels active at the same time ( maybe policy-routing can do the job all the way )
! OR !
.
if your “two-tunnel-machine” can be the ppp-client in the setup … you can set that client-interface into a VRF to work-around the “one-IPeed-client” and hence the routing-problem …
… but as always and before we’re opening that barrel:
better tell the auditorium about the use-case you want to achieve with the setup
