very complicated amahi+network setup

[santiagoafonso]

Hello. I'm looking for help with a very complicated network setup. This are its features:

• I have a Cisco modem/router with address 192.168.0.1 & DHCP is ON. Its only connection is to the (following) linksys 160n router.
• There's a Linksys 160n router in 192.168.1.1. I need it because the wireless range of the modem is very limited (the router gets the gateway info via dhcp from the modem, it is of course 192.168.0.1). DHCP is ON, and the office computers are connected via cable or wifi to this router, using its dhcp server to get their ips and network information (the gateway is still 192.168.1.1 in the computers).
• There's a HP printer which has to be on the 192.168.1.x network, otherwise it won't work.
• I need to connect an the Amahi server to this setup. Apparently, it needs to have its dhcp server on, otherwise it won't work as expected. I need to access it from the rest of the computers in the 192.168.1.x range, but also from the internet.
• I can't change the cisco modem/router to the 192.168.1.x network: it crashes (even if only a computer with a fixed ip is connected to it instead of the linksys router).
• I can't open ports in the modem, which is on the 192.168.0.x network, for the Amahi NAS, which is in the 192.168.1.x network. So I can't access the NAS from outside.

So.... Very complicated setup. Any ideas?

Thanks!!![/size]

This got confusing very quickly.

Perhaps post a quick diagram?

What is the purpose of the cisco router?? why can't you change it without it crashing?? why the complex setup?

It's the cablemodem, and the telco won't change it. I don't know why, but the fact is that is crashes if I try to change its IP.

Could you post the Cisco model number of your router?

Does the Cisco router have multiple LAN ports? If so, you could use it to route to all of your wired computers. You could then set up your second router as an AP to use only for wireless.

If the Cisco router doesn't have enough ports, perhaps you could add a switch to expand them.

I think you really want your Amahi box to be the DHCP server on your network. It really makes things easier.
Can DHCP be turned off in the Cisco router?

My proposed topology would be:

Code: Select all

Internet====>Cisco==>HDA (DHCP) | |=====>comp1 |=====>comp...n |=====>AP (router 2; no DHCP)===>Wireless device(s)

I hope my diagram is understandable!

Thanks for answering! Your proposal wouldn't work b/c the cisco thingy doesn't work in the .1.x network, and the printer doesn't work on the .0.x network. DHCP can apparently be turned off without the modem collapsing. Moreover, I don't know if the linksys can work as just an ap (I'd rather not flash it, beign company hardware). The cisco modem has a single ethernet port.

You state the printer can only work on one ip.
This means its broken, anll HP printers can normally change ip.
Replace it.

The need ot the secon WLAN box is typical with cable boxes but used as you have it is not good.
Connect the WLAN to AP mode and skip the DHCP.
Then you can connect the Amahi in to your network as an gateway.

[santiagoafonso]

So I could turn off dhcp in both the modem and the AP, connect everything to the AP and configure amahi to use the modem as the gateway? That way the modem and the printer would be on their own networks, right?

I'm not sure what you are describing, but the hda needs to have a wired connection to the router. It won't work properly with only a wireless connection.
