I've been able to configure an IPsec VPN to connect from within a virtual router without issue. (external-interface is it's own routing instance and security zone) The st0.X interface associated to the VPN is in inet.0 however and OSPF works across it. Effectively I can have a primary and backup site to site VPN from a remote POP over different WAN links.

This has worked on 11.4R7.5 and 12.1X44.

Hi All
I have a question about SRX VPN support under virtual router;There are two WAN 
links and each link member in different Virtual Router (not inet0), and the VPN 
tunnels must be established from both virtual routers

Per to my search I found two conflict results as below;

Below KB link mention that its supported, and the st0interface and the IKE 
listener interface can be assigned to the custom virtualrouter.

And below document link mention that the IKE listener mustbe member of inet.0 
for the VPN to work.

What if I used Lo0 interface and assigned it to inet.0 andused it as the 
external VPN interface, is this valid solution?
