Hello,
In our environment we have a Zone based firewall on CIsco ASR 1000 XE router, terminating normal IPsec VPN sessions on ZBF. The router has one outgoing physical interface (g0/0/0) connected to ISP as outside Interface and multiple Interfaces on the Inside network on Port channels VLAN/VRF.
The remote access VPN (Easy VPN) is applied using crypto map configuration on the interface connected to ISP.
Now, there was also a requirement to provide IPSec termination on the same physical inteface g0/0/0 to a different customer via a VRF aware Remote access. Two configuration templates were implemented with similar results. IPSec Tunnel comes up fine for the VRF profile but tunnel cannot pass traffic. Ping from IPsec client to an IP address on the Inside network times out and trace route shows that this gets dropped somwhere in the ISP cloud.

Please advise if there is any VPN related configuration issue or a Zone based firewall issue.
