Interconnect 192.xx and 10.XX

[karunakar]

hi there,
we have an environment two lan
one on 192 series (with internet) and other on 10 series(with addl resources).
we have 3com switches 19 series.
is it possible to stitch both of them on a vlan, instead of a router(Current setup but slow)!!

No, unless you assign addresses in both series to all computers, you need a router.

 

[karunakar]

no, all the computers have single NIC

Technically you can place a pc on multiple vlans by assigning them more than one IP on a single nic...and if you get very adventurous you can create virtual nics and use vlan tagging.

Still you don't want to it that way it tends to be a support nightmare.

Pretty much depends how much traffic you are sending between the lans and what type of router you are using. Even consumer grade routers should be able to transfer large amounts of data with little delay. You need to avoid using NAT and just route the traffic. Even with NAT you should be able to transfer well over 100m/sec with a mid level consumer router.

Now a commercial router or layer 3 switch will transfer at full line rates with no delays.

What i'm looking for is a setup with layer 3 switch.,
could you further explain bill001g.

 

[bill001g]

A layer3 switch is technically a router with lots of ports that can be assigned to whatever network you want.

It depends on the vendor how exactly they are configured but most just device virtual interfaces to represent each vlan and by default they route between them.

You would still need a actual router to do function like NAT since few layer3 switches can do that.

Hello addendum to the queries...

I wish to connect our satellite modem/router through a file server (with 2 Nics) then connect the other NIC to our LAN.

NIC1: from router/modem to server have 192.xx.xx.xx series, DHCP enable. NIC2: from server to LAN have 200.xx.xx.xx series.

how can i bridge NIC1 and NIC2 to distribute internet access to other client computer?

In windows all you would need to do is on NIC1, go to properties > Advanced > tick the check box for 'Allow other network users to connect through this computer's internet connection' then select the interface that you want to share with from the drop down.

P.S you might get more responses if you post a seperate thread

Thanks for the headsup!
