Learning about multi subnet networks

(1/2) > >>

Hi all,

I need to learn how to allow network communication between two isolated networks.

Network 1
IP : 192.168.11.xxx

Network 2
Ip : 192.168.251.xxx

Each network has its own router, and I think network 2's router is a firewall/router appliance of some kind.

I am in the process of geting exact brand/model numbers for the network hardware.

they are about 150m apart as the crow flys, and they have already tried a direct cat5 network link, but get huge signal loss on that cable.

I'm thinking of using something like this http://bilcowifi.com/ as it seems to be fairly tough.

So I have to find a way to allow network communication between these two networks. I've never done this sort of thing before, and am starting by googling "bridge multi subnet linux"
Any suggestions welcome :)

100 meters is the accepted maximum distance of a cat5 cable running at 100Mbits/sec. Install a repeater if you
need to go further. You can use 2 ports of a low cost 4 port network switch for this.

That's exactly what they have done.

They put some 4 port switch's along the line, and I'm told that it worked for about two weeks. When I inspected the line, it was all badly corroded with water. It rains there for about an hour every day ! and in wet season it never stops. I think that a hard wire solution would require some heavy duty insulation + very weather resistant gear.

Hi remus
Sounds like an outdoor installation. As long as the outer jacket on the cable is intact, water won't bother it. Exposure
to the suns ultraviolet rays will degrade the jacket over time, probably several years, depending on the material.
Network switches are not meant to be exposed to the elements, especially rain. If they must be outdoors, raise them
off the ground with some bricks, place a bucket over them, and place a couple of bricks on the bucket to keep it in place.
Avoid putting sharp kinks in the cable so as not to distort the signal unnecessarily. An alternative would be a couple
of fiber<->100Base-T converters and some fiber optic cable, maybe Ebay, and you won't have that length limit.

Juanito:
If it's 150m line of sight, then it might be better to go with a wireless link indoors at each end of the gap?
