the network does not work
Please define more precisely: How does it show that the network no longer works ?
Is it already when you activate the VPN server - or only when you establish a VPN connection?
What kind of device/network are you establishing a VPN connection from?
Please note:
The IP ranges of location A and location B must not be the same!
So if you set up a VPN from one Swisscom connection (wired) to another Swisscom connection (wired), you may have exactly the problem you described, as by default both networks run in the 192.168.1.0 range. You must change the IP range of the LAN at one of the two locations to e.g. 192.168.9.0
