Shorewall and LVS-NAT (via fwmark) nat'd machines can't access the outside world directly
Hi guys,
I''m not sure where to post for help on this one, shorewall or lvs, I''ll
start with shorewall (only cause Tom is a gun at this stuff, and is polite
enough to tell me to bugger off to the LVS list if I''m posting in the wrong
one ;)
I have a single box that is my router/firewall/LVS.

Bandwidth limiting a MASQed network.
Hi!
I just recently entered the wonderful world of the so called "advanced
routing" and decided to try and limit the bandwidth of a MASQed network
here and ended up in trouble :(.
The setup is (as far as I can tell) pretty straightforward. eth0 is
connected to the "real" network with a proper IP, and eth2 is 192.168.10.x
(the MASQed network). All of it is basicly right out of

Content based Routing
Just a quick question...
Is there a way to do content based routing (i.e. routing based on a TCP
or UDP port) without using iptables, i.e. using the ip command?
Thanks

Marking returned MASQ'ed packets (ingress, TC, etc.)
Hi Folks,
I''m using a 2.4.x kernel and TC from the iproute2 package
so that I can limit traffic through my gateway. I''m using this
to mark packets when they leave the LAN:
/sbin/ipchains -A forward -j MASQ -i eth0 -s 192.168.1.0/24 -d 0.0.0.0/0
-m 1
When the packets return, I need to have them marked again so that
the ingress filter will limit the bandwidth in the opposite

converting MASQ from ipchains
Hello,
on my old system I''m using ipchains. Can anyone help me with converting rule
/sbin/ipchains -A forward -j MASQ -s source_addr -d destination_addr 443 -p tcp
to shorewall. I know that I can write
eth0 source_addr
to /etc/shorewall/masq file
but I can''t found where I can specify the destination address.
The reason for this is to allow one user (computer) access only to

load balancing between two dsl links
Hi,
I am connected to two DSL providers (DSL 1 - 1Mbps downlink/384kbps
uplink and DSL 2 - 2Mbps downlink/512kpbs uplink)
I would like to only allow ftp, pop3 and http via the DSL 1 and only
smtp, ipsec and pptp via DSL 2.
How can I do so? Can I use iproute to route these protocols?
Below is my ip routing: -
# DSL 1
ip route add 2.2.2.208/30 dev eth0 src 2.2.2.210 table 1
