| hi all,
hi,
|
| I have some in networking , first of all i would like to explain the
| scenario
|
| I have -
| 3 rooms(all consists of atmost 20 computers),
| 3 wifi router(netgear,generates 50 add thru dhcp)
| 1 switch (all rooms are connected to this switch) and
| 1 internet connection ranging from 10.81.0.25-10.81.0.50
|
| What to do?
|
| 1. local inter-connectivity of labs.
| 2. to make 3 access points using 3 wifi routers.
| 3. 3 servers in different rooms.
|
| What I did ?
| 1. made 3 servers and set ips like :
| 10.81.0.25/30/35 ( for 3 servers ) corresponding 192.168.0.3/4/5 (local addr
| for eth1 )
| 255.255.0.0
| 10.81.0.1
| One server in a room having dhcp ranging 192.168.0.10-60
|
| 2. setup NAT for translation 192.168.0.x to 10.81.0.x
|
| 3. configure routers as :
| - 192.168.0.5/6/7 ( for 3 wifi routers in each lab )
|
| 4. local computers having configurtion like
| in 1st room :
| 192.168.0.10-60
| 255.255.255.0
| 192.168.0.3
|
| in 2nd room :
| 192.168.0.61-110
| 255.255.255.0
| 192.168.0.4
|
| in 3rd rom :
| 192.168.0.111-170
| 255.255.255.0
| 192.168.0.5
|
| Now,, problem is :
|
| I cannot ssh ( connect directly to 192.168.0.10-60 from 192.168.0.61-110 or
| 192.168.0.111-170 and vice-versa.
| while
| I can login via tunelling from 192.168.0.10-60 to 10.81.0.25 then
| 10.81.0.30 to 192.168.0.110
|
| what changes should i make to do proper configuration ????
When you try to connect to 192.168.0.10 from 192.168.0.61, connection
won't happen, because 192.168.0.10 belongs to the same logical network
(192.168.0.0/24) as 192.168.0.61, and but since 192.168.0.10 is not
physically present in the 192.168.0.{61-110} network, ARP fails,
therefore no connection.
You need to create route for 192.168.0.{10-60} to route via 10.81.0.25
in 192.168.0.{61-110,111-170} and similarly for others also. Also you
need to add these routes in the 192.168.0.{4,5} .
Instead of assigning 192.168.0.0/24 network for lab PCs, assign /26
addresses. I think you need to redesign logical network.
