Description:
The Advanced VPN Client generally obtains its IP parameters from the dial-in router via IKE Config Mode. For that purpose a dial-in address range has to be configured in the router.
The amount of connected VPN clients is limited to the amount of available IP addresses. If the configured dial-in address range is too small, the remaining VPN clients cannot establish a VPN connection to the router.
This article describes how to change the dial-in address range for IKEv1 as well as IKEv2.
Requirements:
- Advanced VPN Client für Windows as of version 2.3 (download latest version)
- Advanced VPN Client für macOS as of version 2.05 RU1 (download latest version)
Procedure:
The dial-in address range for IKEv1 and IKEv2 has to be configured in different menus.
The dial-in address ranges for IKEv1 and IKEv2 must not overlap with the DHCP address range. Otherwise the overlapped range cannot be used by the DHCP server.
Also the dial-in address ranges for IKEv1 and IKEv2 must not overlap each other, as otherwise a duplicate address assignment can occur!
IKEv1:
1. Open the configuration of the router in LANconfig and go to the menu IPv4 → Addresses.
2. Adapt the dial-in address range to your needs via the First address and Last address.
Use IP addresses from a network configured locally in the router (e.g. INTRANET).
The fields belonging to Name server addresses aren't related to the dial-in parameters, but these are global parameters!
IKEv2:
1. Open the configuration of the router in LANconfig and go to the menu VPN → IKEv2/IPSec → IPv4 addresses.
2. Edit the existing profile and adapt the dial-in address range to your needs via the First address and Last address.
