I've been googling for a while now, trying to forward port 3000 to port 80....
In the past I used to DLink router to forward port 3000 to 80. I recently finished (well, is it ever done anyhow?) setting up my linux box and got it acting as a router.
I want to continue to run Apache on port 80... (1 Reply)

Hi,
from my workplace we use a proxy to connect to the outside world, including external ssh servers.
The problem is that the server is seeing the connection coming from the proxy and knows nothing about the client behind it. The ssh connection itself works fine, but x-forwarding does not work as... (1 Reply)

tc-fw
Firewall mark classifier in tc(8) Linux Firewall mark classifier in tc(8)NAME
fw - fwmark traffic control filter
SYNOPSIS
tc filter ... fw [ classid CLASSID ] [ action ACTION_SPEC ]
DESCRIPTION
the fw filter allows to classify packets based on a previously set fwmark by iptables. If it is identical to the filter's handle, the fil-
ter matches. iptables allows to mark single packets with the MARK target, or whole connections using CONNMARK. The benefit of using this
filter instead of doing the heavy-lifting with tc itself is that on one hand it might be convenient to keep packet filtering and classifi-
cation in one place, possibly having to match a packet just once, and on the other users familiar with iptables but not tc will have a less
hard time adding QoS to their setups.
OPTIONS
classid CLASSID
Push matching packets to the class identified by CLASSID.
action ACTION_SPEC
Apply an action from the generic actions framework on matching packets.
EXAMPLES
Take e.g. the following tc filter statement:
tc filter add ... handle 6 fw classid 1:1
will match if the packet's fwmark value is 6. This is a sample iptables statement marking packets coming in on eth0:
iptables -t mangle -A PREROUTING -i eth0 -j MARK --set-mark 6
