Hi, i have a question if linux is able to do the same thing that
commercial wan simulators do (which cost 7000 $ or more).
Basicly i want to use the following setup.
Linux Router Machine
192.168.0.1 192.168.1.1 Eth0 192.168.10.1 Eth5
192.168.2.1 Eth1 192.168.100.1 WEB Server.
192.168.3.1 Eth2
192.168.4.1 Eth3
192.168.5.1 Eth4
--------------- |Incoming Interfaces Ext If
|Test Clients | -> | Eth0 256 kbit, 250 ms lat Eth5 -> 100 mbit net
|_____________| | Eth1 512 kbit, 100 ms lat Eth5 -> 100 mbit net
| Eth2 1 mbit, 50 ms lat Eth5 -> 100 mbit net
| Eth3 2 mbit, 40 ms lat Eth5 -> 100 mbit net
| Eth4 10 mbit, 10 ms lat Eth5 -> 100 mbit net
Basicly i want to be able from the test client to access a web
application on the 100 mbit network but with a latency and bandwidth
that simulates different WAN links. So for instance i want to be able from
the test client to set default gw, any of the incoming interfaces in the
linux machine. Then i want to send a HTTP request from 192.168.0.1 Client
to 192.168.100.1 Server, and get the bandwidth restricted and also that
the linux box shall add latency on all packets going through.
Another "Wish/Feature" is that from the test client, it shall be possible
to send the Web Request against any of the incoming interfaces with a
PORT specification, for instance 192.168.4.1:8080 and it will be rerouted
to192.168.100.1:8080 with the added latency and bandwidth restriction.
Am i completely lost here, or is it so that this is possible to do in
Linux ??
