Routing for multiple uplinks/providers
Hi, I read the howto of iproute, I have the same case with HOWTO, the
difference is that the whole incoming traffic goes through interface 0, the
other difference is that I do not want to balance the out going traffic,
because I have specific networks to take it throughout another interface.
Mi Case
IF1 --> Input and Output
IF2 --> Only aoutput for three Network

Question on sNAT for multiple external subnets
I''m wondering if the following is possible under recent versions of
shorewall:
1. We have several class-C networks from both UUNet and Internap, both of
which are actually routed over a single inbound ethernet line from UUNet
at our colocation facility: 204.176.148.0/23 and 216.52.83.0/24. This
gives us a total of 3 class-C subnets. All packets for these three subnets
would land on

policy routing at its best
hello list (and martin) ;x
i have now composed my final(?) policy routing design.
the goals i had when beginning with this, for you that have not follow
mine and martins thread, was to 1) only let 192.168.1/24 to see all routes,
2) not route between defined networks, except to and from 192.168.1/24 and 3) not
defined networks should only be able to reach 192.168.1/24.
this might sound simple.

dsmark, unkown
Hi,
I want to use the dsmark, but it always says: "unkown qdisc", although I
have enabled it (y in Network options), and I have my kernel recompiled.
I am using SuSE 8.1, 2.4.20 Kernel, tc available at the HTB site (with
already precompiled HTB queue).
Can anybody find the problem?
thx

one dude about rt_tables
Can I add routes to rt_tables by hand with the vi editor?
If I add a route to that file, it will be there if I reboot the box?
I am sure there are stupid questions but I can''t find the answer into the
papers I have here.

where is "equalize" kernel patch?
I found following paragraph in the man page of iproute2.
equalize
allow packet by packet randomization on multipath routes.
Without this modifier, the route will be frozen to one selected
nexthop, so that load splitting will only occur on per-flow base.
equalize only works if the kernel is patched.

SNAT (or MASQUERADING) and DNAT question
Hi,
The private adresses (192.168.254.0/255.255.255.0) of my network are sent
dynamically by dhcp on my network. The dhcp server is on the firewall which
address is 192.168.254.1/255.255.255.255 (this address is static).
I''ve got a rsync server on this network which is on a separe server. His
address is 192.168.254.200/255.255.255.255 (this address is static).
I want that the users

Public Router using Private Links
I am running a public core router using private links from my provider.
Details:
RH7.3
9 interfaces (all Intel)
eth0 is default gateway and has a private IP address
all other interfaces are links to other routers or networks
eth3 has a public IP address
The core router will rarely need to access sites out on the internet, but when it does it cannot get there because the eth0 has a private IP

DNAT "without" SNAT?
Hi!
First of all, let me say a big "thank you" to Tom for creating
shorewall. I''ve been using it for a few months now and it''s such a
relief to not have to resort to OpenBSD''s pf (which is so much more sane
than Linux'' iptables madness) for the most basic firewalling tasks.
I have a question that I didn''t seem to be able to find in the FAQ.

Route policy preference value
Assuming if I have rules matching the same packet,
the one chosen is the lower preference value or
the high ?
For example
# ip rule list
....
100 from 192.168.1.0/24 lookup main
200 from all fwmark 5 lookup first
.....
Packet is matching both rules, the one with priority/preference
100 or 200 is selected ?

rsync: future of the --server option
Hello list members,
I notice here that the --server option is listed as undocumented.
http://rsync.samba.org/rsync/fom-serve/cache/88.html
My question is that the --server option is not documented, and I'd like
not to build functionality into one of my systems without trusting that it
will be there in the future.
I was able to find the --server option simply by watching the rsync
entries

Routing based on fwmark
I''m having trouble routing on high fwmarks, I want to use a lot of
different marks for 2 routes so that I can QoS based on the marks
ip rule looks like this:

32752: from all fwmark 30 lookup dslout
32753: from all fwmark 29 lookup dslout

snooping - the crux of the problem
I have a computer with two interfaces, say with addresses 192.168.1.1
and 192.168.1.2. I want to set up routing such that when I ping
192.168.1.1 it goes out through 192.168.1.2 and not to the local
interface.
Is this possible - all my attempts so far have been unsuccessful? If
so, pointers, etc. would be gratefully appreciated.
Jim
