[LARTC] Ho do i manage NAT'ed egress bandwidht?

[Joost Kraaijeveld]

Hi,

I have a Debian based NAT router. How can I manage upstream egress
bandwidth based on the LAN ipadress in the network below? My goal is
that host1 get a minumum of 10Mbit up/down and host2 gets a minimum of
90Mbit up/down, both max 100Mbit up/down?

           targethost
         172.16.255.254
                |
                |
           172.16.0.1
            natrouter
          172.31.255.254          
                |
                |
    + ----------------------+
    |                       |
172.31.0.1		172.31.0.2
host1			host2


TIA

You can use iptables MARK target in PREROUTING or FORWARD chain of
nat table in conjuction with a fw filter (see tc filter help).

Hi Joost,

This sounds like a situation where you would probably use HTB to shape your 
bandwidth.

You can search the archives for info on HTB, read the LARTC pages but you may 
find more specific information relating to your situation at the below links.

Or you can just use this ready made HTB script on your server which should 
suit your problem description without much extra work on your behalf.

Lee
