turn WRT54G 4-port lan switch to 4-port router?

    Is there any software that can turn the 4-port LAN switch on the WRT54G into a 4-port LAN router? I have tried to see if there is a firmware hack that assigns an independent IP address to each of the 4 LAN ports. As opposed to having all 4 ports use the same IP.

    Perhaps you could explain exactly what you're trying to do and we can help you out better.

    :?:

    I think he means a router which has multiple routed interfaces, similar to a Nortel ASN

    ????

    Do you want each of the LAN port connections to be able to get a WAN IP rather than using NAT?

    With a true router, each port would receive it's own IP address. 5 ports, 5 IP addresses. The WRT54G has 5 ports, 1 WAN port and 4 LAN ports. The WAN port has it’s own MAC and IP address. The 4 LAN ports share the same MAC address and IP address. The 4-Port LAN part of the WRT54G is not acting as a 4-port router but as a 4-port switch.

    I want to assign an IP address to each of the 5-ports on the router and create 5 separate Networks addresses off the router. WAN port will be connected to internet, with WRT54G mode set to Gateway. Each LAN port will have three computers connected. My desired configuration is below:

    Network subnet mask: 255.255.255.0
    WAN port IP address: 192.168.1.1
    First LAN port IP address: 1923.168.2.1
    Second LAN port IP address: 1923.168.2.1
    Third LAN port IP address: 1923.168.3.1
    Fourth LAN port IP address: 1923.168.4.1

    I have loaded firmware on Cisco Switches before that would simulate full routing. Even though all ports on Switch had one MAC address, the software would allow a different IP address, with different Network addresses, to be assigned to each switch port.

    Is there any firmware that will allow me to assign a unique IP address to each of the 4 LAN ports, instead 4 LAN ports sharing 1 IP address?

    Perhaps I'm still a bit confused as to what you want to do and or why. I think the confusion is you keep referring to assigning IPs to ports versus sharing IPs.

    I think what you are getting at is running each port as a separate VLAN device

    This is possible with the latest Sveasoft release Sartori pre-3.10. A great description of the work on the ADM6996.o module is discussed here - You should be able to do exactly what you're looking for with this method.

    Sorry for the confusion.

    Hey no problem, glad to be of help.

    Isn't it great how much power these little routers have the potential for? Where else can you get a router capable of VLANs for $79 (59 + 20 for the Sveasoft firmware) ?

    Will Satori V2.00.8.7 pre1 (Reports as 2.00.8.6) work with VLAN or must it be Sartori pre-3.10.

    Answered My own question. It does!
