IP vs. Bridging

Typical Bridging setup

Using TCP/IP and Bridging

Local IP communication

CAUTION

Basically, Bridging does not require any IP address at all: neither in your PC(s), nor in your AST350i.

However, in case of Internet access, private IP networking or in case the Bridging packet service is used for Bridged PPPoE, your PC(s) must be configured for TCP/IP.

In most cases, your SP will require you to use DHCP for your PC. In this case the DHCP server is at the remote side of the DSL connection. Therefore, your AST350i's DHCP server must be disabled.

Your SP may:

￿Provide you with an IP address

￿Require you to use DHCP.

Alternatively, a second but Private IP address can be manually configured for local IP communication. It depends on your OS whether it supports this combination.

e.g. Microsoft supports Logical Multihoming via Registry keys.

Bridging & DHCP Service

The AST350i DHCP server is by default disabled.

In case you use your AST350i in Bridging mode and your ISP requires you to enable DHCP in your PC(s), the DHCP server inside the AST350i must be disabled to avoid conflicts between two DHCP servers being active at the same time.

Setting the DHCP modes of your AST350i is described in section 6.3.
