Wrong behaviour in policy routing
Hi!
I get this strange behaviour... I don''t know how some packets get into
wrong rules.
My rules are those:
0: from all lookup local
50: from all lookup main
201: from 192.168.17.0/28 lookup 201
202: from 192.168.16.0/28 lookup 202
222: from all lookup 222
32766: from all lookup main
32767: from all lookup default
Table main has:
192.168.17.0/28 dev eth2

About routing, nat, the FORWARD chain, and a bit of Julian''s patches
Hi!
I''m still trying to solve the problem, about which I already posted in
these lists... I''ve been trying to understand where packet routing and
NAT is being done. The schemes are quite clear, when it''s about the
_first_ packet of a NAT connection (when it enters the NAT table). But
it isn''t that clear about the packets NAT''ed by the connection

Re; Multihomed DHCP and PXE?
That is what I thought, but just to clarify:
I am using static dhcp hosts in the dhcpd.conf and our network config.
is similar to this:

Ip route cache problem
Hello,
I need some help about a routing problem on a complex configuration.
The problem is that I can''t reach from services outside from my DMZ.
The scenario is a gateway linked to three internet connections, so that
I used three distinct iproute2 tables for routing. The gw is running
ipvs for balancing over the dmz''s servers.
DMZ servers are on 192.168.1.0/24 network, .

Network problem: packets are lost in domU
Hello,
I am having big problems with Xen virtual network interfaces. First
I tried typical bridge support, no luck. The packets sent from dom0
to domU seemed to disappear somewhere. Then, to debug the problem

problem.
I am using Xen 3.0.4-1 and Linux 2.6.16.x in both dom0 and domU.
I have tried kernel 2.6.16.35 and 2.6.16.41.

About multihop route decision without Julian''s patches
As I''ve read in
http://gnumonks.org/papers/netfilter-lk2000/presentation.html, there''s
said about the "nat" netfilter table:
"This table is different from the ''filter'' table, in that only the
first packet of a new connection will traverse the table. The result
of this traversal is then applied to all future packets of the same
connection."
