V-Portal Linksys set up

Posts: 2 · New Forum Member Joined: Aug 26, 2008 Posts: 2

I just got a V-portal device for a fax line. My network is setup through a Linksys WRT54G. Gateway Address: 192.168.9.1 IP range: 192.168.9.100 - 192.168.9.149 I have a MFP fax/scanner machine. It has a static IP of 192.168.9.145 When I plug the V-portal in behind my router and then plug my MFP into the V-portal I can not print or scan on my network. All the computers on my network are 192.168.9.xxx and they can not see the MFP which is was set to 192.168.9.145 ANY SUGGESTIONS?

Why are you plugging the MFP into the V-Portal? The MFP should be connected to an available ethernet port on the linksys router.

You have a couple of problems with your set up as described.

The VPortal connects to the linksys on one of the available linksys IP's 192.168.9.100 - 192.168.9.149, but then it sets a LAN range from the Vportal of 192.168.15.2 to 192.168.15.255, your MFP is effectively being blocked as it is on another subnet.

I agree you should plug your MFP in to the linksys, but change the static IP of the MFP to something below 192.168.9.100, as the DHCP could "possibly" assign 192.168.9.145 to another device, causing a conflict.

Why change the static IP of the MFP? How could the static IP of the MFP possibly be assigned to another device when the MFP has a static IP assigned by the Linksys router? Isn't that the reason for assigning the MFP a static IP so it won't be assigned to another device?

Usually one sets the static IP on the device, and it just takes that IP from the router. Also, one usually excludes those IPs from the DHCP range to eleminate conflicts. If you have reserved that IP on the Linksys in some way (not sure of how you would do that other than setting up a static route, which is not the correct way to do this) and then set that device to that IP, you may be OK. Usually a static route is to move traffic to another network.

But telling the router to assign via DHCP the same IP seems to me to set up the potential for a conflict.

I don't understand how there could be a potential conflict with the ip address of the MFP being assigned to another device. If the Linksys router is set up for static DHCP, and has assigned the IP address of 192.168.9.145 to the MFP, the MFP will always grab the same IP address from the routers DHCP server thus eliminating the potential of said address being assigned to any other device on the network.

DHCP only keeps track of what it assigns. I have seen a device set to a static IP (on the device) and when the DHCP tries to assign that address, a lot of problems start happening on the network.

BTW, you said the router assigns the address. A static IP is where the device assigns the address to itself. And yes, if it has that address assigned to it via dhcp, it will always get it as long as the lease does not expire.

BTW, I never heard of "static dhcp". Seems to be a non sequitur.

If you have a Linksys router that supports third party firmware such as Tomato, static dhcp is supported. Your statement of, "A static IP is where the device assigns the address to itself," I don't disagree with. With my setup, my Linksys WRT54GL assigns the IP address via the dhcp server and if I want to make that address permanent or static to any device connected via ethernet or wireless, I can make it a static IP regardless when the lease expires...it will always retain the same IP.

Try Googling "Static DHCP" for more information.

Is escoweb running WRT or Tomato? If not,he is probably not running a firmware with static DHCP. He then is setting himself up for a conflict, my only point.

I didn't realize until we had this conversation that static dhcp is not a standard feature with the stock Linksys firmware. All the more reason to upgrade your stock Linksys firmware to Tomato or DD-WRT if your router supports it.
