Using dynamic DNS you can access a module with dynamic IP address over the Fully Qualified Domain Name (FQDN).
The security module reports the current WAN IP over which the module can be reached to a provider for dynamic DNS (DynDNS.org, no-ip.com, for example). The provider makes sure that DNS queries to the FQDN of the module are answered with the WAN IP of the module.
The overview below shows which security modules support dynamic DNS as VPN server and VPN client and can use it to communicate with each other.
|SCALANCE S V3
|SOFTNET Security Client (SSC)
|SCALANCE S V3
1) Communication using dynamic DNS is possible with SSC V3 onwards.
2) Communication using dynamic DNS is possible with SSC V4 onwards.
The CPx43-1 Advanced does not support dynamic DNS.
The SCALANCE S V3 is not a DNS client. It can only transmit its current IP address to the DNS server, but cannot resolve any domain names.
The SCALANCE S V3 supports the following providers: DynDNS.org, non-ip.com or a freely defined service.
The SCALANCE M875 is compatible with the DNS services of the provider DynDNS.org. For dynDNS the M875 needs a public IP address that can be reached from the internet.
More information about the security modules is available in the manuals below.
