Any solution for this need?

by amar080280 / November 15, 2012 10:12 AM PST

I have telecom equipments having LMP (Local maintenance port) with IP address on every equipment.

We have connected LMP port from individual equipments to seperate desktop machines, (desktop machine IP is kept in the same subnet as LMP IP). With this arrangement we can open application from desktop machines that talks with LMP port (application uses SSH)..

Problem we are facing with this arrangement is:
1 We have to lay lengthy LAN cables from individual LMP ports to desktop machines.
2. If we need connect LMP port to different desktop (these equipments are shared) machine, we need to re-route the cables.

I am looking for a solution that will:
1. connect LMP ports from individual equipments to a single server/switch, which will enable me to connect to any equipment from any desktop machine.

Is there a solution?
I am looking around for solution but not getting any. All LMP ports has same IP address, so how do we seperate them in a single switch so that I can connect to any of them individually from desktop application? Not able to get clear picture if any CISCO switch can be used with VLAN and tunneling to solve the purpose.

pls help

I'm thinking a managed switch.

That way I can turn on and off the port I need to access. Remember that you never wrote they need to be online at the same time so with that, ask Cisco which managed switch lets you enable/disable the ports as needed.

I have a second solution where we use a router per LMP but it's a bit too techy and at 40 bucks a connection may upset some folk on the budget.

Bob, thanks for quick reply. All the LMP needs to be online all the time.
And second solution comes with some investment and yes may not go through Sad

The second solution uses the NAT in the router.

With a common router I can assign an IP to the WAN port (which BTW must not be on a 192.168.255.n LAN) then put the into the DMZ of the router. The LMP goes to the LAN port of the router. Since we only get one NAT per router, we use as many routers as required.

If I wanted to test this setup, I'd try something small like and yes, I'd turn off the WiFi portion.

you mean e.g use 10 routers for connecting 10 LMP ports? I will try to pursue this option further but are you aware of a switch/router which does the job of these 10 individual routers? Or can I use VLAN in switch to differentiate individual LMP port and then connect to any VLAN from from WAN?

Yes I know of such a thing but horrificly expensive.

It's a custom single board computer in the 6 figure range and not available without a suitcase of cash.

The solution I noted is in the range that you can try one for a test then duplicate as required. So yes. I'm sure there are other solutions but it sounded as if you didn't want to invest the million bucks.

Will this solution work

Thinking if following will work

Connect all LMP to a machine having multiple LAN ports... Put VNC server on this machine and then access from anywhere needed?

Will it work?
