Appendix B Triangle Route

NN47923-501

1

A computer on the LAN initiates a connection by sending out a SYN packet
to a receiving server on the WAN.

2

The Business Secure Router reroutes the SYN packet through Gateway

B

on

the LAN to the WAN.

3

The reply from the WAN goes directly to the computer on the LAN without
going through the Business Secure Router.

As a result, the Business Secure Router resets the connection, as the connection is
not acknowledged.

Triangle Route Problem

The Triangle Route Solutions

IP aliasing

Using IP alias, you can partition your network into logical sections over the same
Ethernet interface. Your Business Secure Router supports up to three logical LAN
interfaces with the Business Secure Router being the gateway for each logical
network. By putting your LAN and Gateway

B

in different subnets, all returning

network traffic must pass through the Business Secure Router to your LAN. The
following steps describe such a scenario.

1

A computer on the LAN initiates a connection by sending a SYN packet to a
receiving server on the WAN.
