Note
CP-8000, CP-8021, CP-8022 and the remote station must be configured in different networks when IPSec
VPN is used.
The parameters Remote site <x> |Subnet IP address and Remote site <x> |Subnet mask
are necessary for the SICAM A8000 internal router function.
The certificate SHA256 must be used (obsolete: SHA1).
In Google Chrome ® the cache must be deleted before the logon with SICAM WEB via https.
For routing in 2 tunnels it is necessary to define both remote stations (Remote site 1 and Remote site 2).
