IPSec VPN issues with MAX 700

Hi. I recently started working with the Pepwave MAX 700 playing around with it’s IPSec VPN capability. I am succesful in getting the 700 to establish a VPN with a neighboring Cisco 2811. The protected subnet behind the 700 is the default with the default DHCP range. The subnet on the 2811 belongs to a loopback and is a /32 of The crypto map on the 2811 matches traffic from the loopback to the remote protected subnet.

What I’m observing is traffic that I send sourced from the loopback on the 2811 to the 700’s protected subnet is rejected at the WAN interface on the 700. I see the following message in the device event log on the 700[280423.456000]Denied CONN=WAN1 SRC= DST= LEN=100 PROTO=ICMP TYPE=8 CODE=0

Now, I know the VPN is up, and I am matching traffic against the ACL for my crypto map on the 2811. I can see that the 2811 is encrypting the traffic by viewing the IPSec SA that is established on the 2811. I’ve tried adding a rule [above the existing deny rule] to the “Inbound Firewall Rules” permitting the ICMP traffic that I am testing with. I assume that rule set applies inbound on the WAN interface? But I still am not getting traffic to pass that is initially sourced from the 2811 to the host behind the 700.

I am able to receive traffic if it is sourced from the 700’s host. i.e. - ping from the –> In this scenario I am able to receive my ICMP reply.

NAT is enabled on the WAN interface

Any feedback would be appreciated.


This sounds like something to do with the firewall rule. Please open up a support ticket with us here so we can take a closer look at this.
