Cannot get Cisco ASA 5505 to pass VPN traffic

[jonathanbaird]

Hi, 

I am having some trouble getting my Cisco ASA to pass VPN traffic from the Cisco ASA to a DrayTek 2860. The tunnel is up and traffic from the DryaTek 2860 reaches the Cisco ASA but not vice versa. I have checked NAT rules and from what I can see it looks to be correct. My config is below. Any assistance with this would be greatly appreciated.

Can anybody help with this please?

[Rahul Govindan]

I would recommend 2 things:

1) Remove "crypto map wan_map 1 set connection-type answer-only". I have seen this does not play well with 3rd party VPN devices. 

2) Debug further by using the following commands:

packet-tracer input <inside-intf> icmp <inside-host-ip> 8 0 <remote-host-ip> detailed

This should show you the packet processing steps on the ASA and where the packet could be potentially dropped.
