# Limitations

* LANs connected to a given VPN gateway must all belong to the same [<mark style="color:blue;">Virtual Datacenter (VDC)</mark>](https://docs.ionos.com/cloud/support/general-information/glossary-of-terms#virtual-data-center-vdc).
* Currently, only static routing is supported; dynamic routing and Border Gateway Protocol (BGP) routing are not available.
* Interface IP is not DHCP aware. Ensure that you use private LAN IP addresses that are not already assigned via DHCP or are outside the DHCP range (.2-.10).
* Tunnel endpoint and Gateway IP addresses are IPv4 only.
* PSK and keypairs are not auto-created by the product. Hence, ensure that you provide them wherever necessary.
* Remember to delete the VPN gateway before deleting the connected VDC.
