## Symptoms

- * Remote Access VPN users cannot connect.

* Logs display the error "*Rulebase internal error*."

## Cause

This issue occurs due to one these reasons:

1. **Corrupted Entry in `metagroup_rules_g` Kernel Table**

   As described in [sk175704](https://support.checkpoint.com/results/sk/sk175704), a corrupted entry in the metagroup_rules_g kernel table causes the Remote Access VPN authentication to fail.
2. **Nested Groups and Permission Limitations**

   * Due to an R81.10.10 code change in the Identity Awareness Blade, Remote Access VPN permissions do not extend to nested groups.

   * The Rule Base includes nested Access Groups or LDAP Groups with Remote Access permissions.
