Need some help setting up this network properly, please.

It's likely that the 5150 is on a different IP network than any of the other machines. All the others are receiving their IP addresses from the DHCP server on the DI-604, but the 5150 is getting its IP address from the WRT54G's DHCP server. If you add the IP addresses to each interface on your diagram, you'll see what this leads to.

The simplest fix is to eliminate one of the DHCP servers. There are two ways you could do that. The WRT54G can likely be put in "bridge" mode. Alternatively, you could just eliminate the DI-604 and connect the wired devices directly to the WRT54G or the hub.

Ya, the IPs are slightly different. the 5 computers on the Hub and Dl-604 are all 192.168.0.10x, and the 5150's IP is 192.168.1.100. I have port 4 on the Dl-604 going into the WAN port on the WRT54G, and the Dl-604 gave the WRT54G the IP of 192.168.0.103.

Not sure if it helps or means anything, but I tried connecting to an FTP on one of the computers on the Dl-604, from the 5150, and it connected. I used the computer's internal IP as well, given to it by the Dl-604, and I was able to trasnfer files back and forth. Also, on a Dl-604 computer, I can ping the WRT54G, but I can not ping the 5150, the 5150 is also in DMZ. And from the 5150, I can ping any computer on the DL-604, as well as the Dl-604 it self.

Do you know how I would put it into a "bridge" mode? because I sort of need to have both, I have an Xbox, and a PS2 I'm going to connect to the WRT54G's wired ports. And I wouldnt mind getting rid of the hub, as its much too slow :D

Theres a group of settings under a section called "Advanced Routing" where you can select its Operating Mode, and theres a choise between 'Gateway' and 'Router' I tried playing with that, but I dont know how to correctly set that part up, and ended up hosing the whole thing, and had to reset it back to factory specs. :D And the help page isnt helpful. The settings are:

Dynamic Routing (RIP): Disabled, LAN & Wireless, WAN (Internet), Both

Enter Route Name: (I figured this part out :D)

Destination LAN IP:

Subnet Mask:

Default gateway:

Interface: LAN & Wireless, WAN (Internet)

 

Thanks

I recently set up a WRT54G, but it was directly connected to a cable modem, so I didn't catch the fact that there's no explicit bridge mode for that beast! According to an newsgroup posting I found, the WRT54G *will not* act as a bridge device unless the WAN connection's plugged into one of the LAN ports.

The problem with LAN games that you're encountering is almost certainly a result of the fact that the 5150's on a different LAN than the rest of the machines, and the games are relying on broadcasts for some purpose. By design, routers don't pass broadcasts between LANs. The inability to connect network drives supports that, since certain steps in resolving the name of the other machines rely on broadcasts unless there's some other way (like WINS) to resolve names.

"Proof of concept" would be to connect the hub and the two PCs currently on the D-Link to the Ethernet 10/100 ports on the WRT54G. That would give all the PCs IP addresses from the WRT54G's DHCP server. Leave the WAN side of the WRT54G connected to the D-Link for this setup.

If that works, the point's made that if all the PCs are on the same LAN (192.168.1.10x, from the DHCP server on the WRT54G), LAN games and sharing work. There are then several possibilities.

One is to turn off the DHCP server in the WRT54G, and connect the cable to the D-Link up to one of the LAN ports on the WRT54G. In that mode, everything would get IP addresses from the D-Link's DHCP server (192.168.0.10x).

Another is to eliminate the D-Link and connect the WRT54G's WAN side to the DSL modem. The WRT54G would act as the DHCP server for the LAN in that case. That would be my choice, because it removes unnecessary complexity from the setup.

Either way, I'd just replace the 10 mbit hub with a 10/100 switch, so the PCs that are able to run at 100 mbits/full duplex are connected to a device that supports that speed. I have several Linksys workgroup switches in my setup, and they work very well.

By the way, thanks for publishing that network diagram. It made it much easier to understand your setup.

Thanks so so so very very much much!! :D I disabled the DHCP on the WRT54G, and linked the Dl-604 into a LAN port on the WRT54G, released and renewed the IP on the 5150, and it worked, I can see games, share etc.

about the pic, I thought it was needed to help show, cause I was confused my self, and drawing it, help me understand my own layout as well, not to mention it can explain things easier than words :D

 

Again, thanks

Cool! Thanks for the feedback!

And yep, the main reason I do network diagrams of complex setups is to keep myself from getting confused!
