## Symptoms

- * Users of a Remote Access VPN client cannot access resources located behind a Remote Access VPN Gateway. The Remote Access VPN client shows: "*IKE Negotiation with the gateway has failed. Make sure the user is properly defined on the firewall.*"
* The Remote Access VPN Gateway has installed R81.20 Jumbo Hotfix Accumulator Take 96 or higher / R81.10 Jumbo Hotfix Accumulator Take 173.
* In the CLI Expert Mode of the Remote Access VPN Gateway / Cluster Member, output of `hcp -r all HCP Reports` shows core dumps related to problems with `iked` and `vpnd`.
* In the CLI of the Remote Access VPN Gateway, /*var/log/messages* shows errors that are similar to this: `kernel:iked[-]: segfault at 19 ip - sp - error 4 in ike[-]`
* IKED debugs (or VPND debugs if IKED is disabled) show `__MsgObj_internal_error:_NULL_obj__ error can be seen on IKED debugs`

## Cause

There is a problem with the `iked` and `vpnd `processes on the Remote Access VPN Gateway due to aggressive DDOS protection.
