On the same site I have a 10.1.0.0 / 21 network with a switch and router
for internet access. The router IP addresses its 10.1.1.1/21 and all
devices on the 10.1.0.0 / 21 use this router to access internet.
LAN 1 and LAN 2 are not connected and I cannot change the 192.168.1.0/24
network to have 10.1.0.0 / 21 addresses.
Without installing the additional NIC in to 192.168.1.10/24 PC and giving
it 10.1.0.0 / 21 how else can I access the 192.168.1.10/24 PC.
I understand that I physically need to join the LAN 1 and LAN 2 Switches
using Ethernet cable which is not an issue.
Put the PC on the regular LAN with the 10.1.0.0/21 address.
Add the 192 address to the same nic as a "secondary" address in the Advanced
section of the nics TCP/IP properties. The 10 address will be the *primary*
address.
The "Video Wall" must be on the "same wire" as the rest of the LAN.
It is a "kludge",..there is no way I would do it that way,...but it would
work
If you have intrusion detection systems on the 10 LAN they will go nuts
seeing the 192 addresses on the same wire,...and you 'll have to ignore the
alerts
On the 192.168.1.10/24 how can I use the route add to add a permanent
route to have communication between LAN 1 and a device on LAN 2 with IP
address of 192.168.1.10/24 PC?
Can I add a 10.1.0.0 / 21 static IP address to the existing NIC on device
in LAN two with current IP of 192.168.1.10/24?
There is no "Route",...because there is no "routing" happening here. The PC
is just simply having dual identities off the same nic,...again,..bad
idea,...I wouldn't do it.
Side note:
Ethernet begins to nose-dive on effieciency as it gets over 250-300 Hosts.
You should never use a Mask smaller than /24 unless you are Supernetting
over a Backbone. So you should not be using /21. If you have exceeded 254
Hosts on the LAN then you should add a LAN Router to the LAN and add one or
more subnets with all subnets using a 254 Host segment (/24). Not only
would this make the LAN more efficient, but it would have solved the issue
with the Video Wall before it ever happened.
Any company with more than 254 hosts is never going to convince me that they
cannot afford to buy a simple LAN Router. If they can't,...they are about
to go out of business any day now and you should flee. Some commercial
grade Firewalls can have muliple LAN Interefaces and can pull "double-duty"
as a LAN Router although they tend to not have all the routing features that
a real LAN Router can have.
