Correct. libreswan does not consult a DHCP server. It assumes it has
full authority to assign anything from its given addresspool.

That seems more likely to be a generic routing/firewall issue than a
VPN issue. Make sure the VPN server has an IP in the addresspool range
(could be an additional IP on the physical network card). Then try
and ping from your regular network to the IP on your VPN server.
Also ensure you are not accidentally NATing the new 192.168.6.0/24
range elsewhere in your network.
