Usage Notes
DHCP Route Renewal in Windows 2000 and Windows XP
In a Windows 2000 or Windows XP environment, if the public network matches
the private network (for example, a public IP address of 192.168.1.5, with a
subnet mask of 255.255.0.0, and an identical private IP address) and the public
network’s route metric is 1, then traffic might not be tunneled to the private
network (CSCdz88896). The same problem can occur if you are using a virtual
adapter and the public metric is smaller than the virtual adapter metric.
In Windows 2000 and Windows XP, you can increase the metric of the public
network by doing the following steps:
Step 1 Select Start > Settings > Control Panel > Network and Dial-up Connections.
Step 2 Select the public interface and click properties for the public interface.
Step 3 Select Internet Protocol (TCP/IP) and get the properties for the Internet Protocol
(TCP/IP).
Step 4 Click Advanced, and set the interface metric to 2 or greater.
Solaris Client Using Routed RIP Might Lose Connectivity
If the VPN Client running in the Solaris environment uses routed RIP to learn its
default route, you might lose connectivity. This is because RIP is blocked when
the VPN Client is connected in all tunneling mode (CSCdv75825).
Data Meant for Private Network Stays Local if VPN Client’s Local
Network Is on Same IP Subnet as Remote Private Network
This problem occurs only with the VPN Client, Release 4.0 and only with Virtual
Adapter (Windows 2000 and Windows XP), when the VPN Client’s local network
is on the same IP subnet as the remote private network. When a VPN connection
is up, data meant for the private network stays local. For example:
192.168.1.0/255.255.255.0
