Chapter 4 Interconnection of the headquarters and branch offices
22
If a remote host is tested through IP address and it does not respond, check configuration
of the traffic rules or/and find out whether the subnets do not collide (i.e. whether the same
subnet is not used at both ends of the tunnel).
If an IP address is tested successfully and an error is reported (Unknown host) when a corre-
sponding DNS name is tested, then check configuration of the DNS.
Note: VPN clients connecting to the headquarters server can access both the headquarters and
the branch office (the access is not limited by any restrictions). Therefore, it is recommended
to test connection to both networks also from the VPN client.
