Your setup with the Belkin is working because the Belkin is providing the translation from the outbound interface of the Cisco, to the STATIC IP addresses on teh downstream Linksys that you set static IP’s on. You could use the 2950 and remove the Belkin if
a) You allow the Linksys to pick up DHCP addresses from the Cisco (assuming it provides DHCP addresses for clients)
- or -
b) You set the Linksys devices to be 12.179.xxx.xxx addresses (with appropriate gateway/mask of the cisco) so they match the addresses of the Cisco

By the way, The belkin ip address is set to 192.168.0.1/255.255.255.0, the cisco 2950 ip address is set to 192.168.0.2/255.255.255.0. Maybe I just have all the addresses wrong. The AP’s and clients can be set to dhcp, but I have not tried them that way. I have the default gateway on the belkin pointing back to f0/0 on the 1841. Tried it that way on the 2900 and 2950. No luck, but as I said, I have reset the 2950 to factory default, but have not tried it yet. Thanks

Hi, I hope I can give a clear picture of what I have setup. My t1 line comes into the cisco 1841 router, I have only one line, and only one dsu module installed. the serial o/o/o ip is set to 12.94.xxx.xxx /255.255.255.252. Coming out 0f the 1841 is one fast ethernet port 0/0 set to 12.179.xxx.xxx, with a lan range of .128-.255 There are two ethernet ports, f0/1 is not used, or setup as far as I know. What i have next is a belkin home wirelss router/switch combo, $49 at walmart, the cable for 1841 f0/0 is plugged into the modem port on the belkin. All data to the AP’s comes from the 4 switch ports on the belkin. I have 4 AP’s but am using only 3 right now. The 4th switch port on the belkin goes to my computer which I monitor the system with. I have plugged it straight to the computer, and to the 2950, then to the computer, I get internet either way to the computer. I don’t neccessarily have to have this computer running, it only only so I can see what is going on in the system. The system will run with only the 1841, the belkin, and AP’s. The AP’a only transmit and recive data, they are mounted on a 140 foot tower outside. The ip addresses are set to static, 192.168.0.20, 192.168.0.21, 192.168.0.22, 192.168.0.23, with the last one not being used right now. All clients are set to static in the same ip range. If I remove theAP cables from the belkin and put them in the 2950, they will work as long as the cable from the 1841 is plugged into the modem port on the belkin and a cable from any switch port on the belkin runs to any port on the 2950. I sorry for that being so lengthy. If you bypass the belkin altogether, no internet to AP’ or the computer. I upgraded the firmware on the 2950 to the latest version last night, and reset it to factory default. I have not tried it yet since they is so much traffic on the system right now. As soon as it slows down some, I am going to shut the system dow and connect the 2950 to the 1841 and see what happens.

I appreciated you help, I have been working on this for weeks now, with the 2900 and now the 2950. Thanks a lot. Ed
