4.4.4 What Can Go Wrong
• VPN rule settings violate the the ZyWALL IPSec VPN Client restrictions:
Check that the rule does not contain AH active protocol, NULL encryption, SHA512
authentication, or a subnet/range remote policy.
The ZyWALL IPSec VPN Client can also indicate rule violations. Check its warning screen.
Although the rule settings may be valid, whether the tunnel actually works depends on the
network environment. For example, a remote policy IP address for a server may be valid, but
the server may be down or have an actual different IP address.
• There is a login problem:
Reenter the user name (Login) and password in the ZyWALL IPSec VPN Client exactly as
configured on the ZyWALL or the external authentication server.
Check that the client authentication method selected on the ZyWALL is where the user name
and password are configured . For example, if the user name and password are configured on
the ZyWALL, then the configured authentication method should be Local.
