IPSEC VPN Traffic ping not working

[Pkay983]

Hello, 

we have a working tunnel (up) from one location to the other.

From the remote location, the ping arrives our firewall, but it does not reply to them (they get timeout).

Our ping seems to go through our firewall, but does not arrive the remote location (we also get timeout).

Both traffic is visible in the logs.

Policys from remote subnet to local subnet are there and vise versa. At least on our location, I'm waiting for response from the remote location.

Also we have a (in my opinion) working static route for the remote subnet, pointing to the vpn-connection.

Same interface / ip is also used for a second ipsec tunnel and this one is working fine (I get icmp: echo reply)

Any ideas or troubleshooting hints?

thanks

You have to, or ask whoever managing the remote end, sniff and run IKE debug on the remote device, since the local end seems to be fine based on your description.
