Firewall Protection The firewall protection provided by the ISDN Internet Router is an
intrinsic side effect of IP sharing. All users on the LAN share a single
external IP address. From the external viewpoint, there is no network, only a
single device.
For internal users, the ISDN Internet Router acts as a "transparent proxy
server", translating the multiple internal IP addresses into a single external
IP address.
For external requests, any attempt to connect to local resources is
blocked. The ISDN Internet Router will not "reverse translate" from a global IP
address to a local IP address.
This type of "natural" firewall provides an impregnable barrier against
malicious attacks.
