RE: Transparent proxy

It's a little different config than I have, but it looks ok to me.  

What's haproxy -vv give?

I have:

[root#haf1 etc]# haproxy -vv

HA-Proxy version 1.3.15.7 2008/12/04

Copyright 2000-2008 Willy Tarreau <w#1wt.eu>  

Build options :

  TARGET = linux26

  CPU = generic

  CC = gcc

  CFLAGS = -O2 -g

  OPTIONS = USE_LINUX_TPROXY=1   (I know, I am a little behind, but if it's not broke.)  

When you say, haproxy says 503., I assume it doesn't actually say that but that's what a web browser gets back from it?  

I assume the web servers have the haproxy's private IP address as their default route? If they are going to some other device as a NAT gateway, that will not work.

Do they show a SYN_RECV or ESTABLISHED connection from the public client trying to connect?

Subject: Transparent proxy  

Hello everybody, I have a problem with haproxy (1.3.17) and kernel 2.6.29  

I have successfully recompiled my kernel with TPROXY modules and installed haproxy (compiled from source with tproxy option enabled) and installed iptables 1.4.3 (that have tproxy patch).

Now I can't use transparent proxy function: if I leave in haproxy.cfg this line "source 0.0.0.0 usesrc clientip" haproxy say "503 - Service unavailable".

If I comment out the line, everything work fine (without transparent proxy).  

My situation:  

haproxy with two ethernet device: first one for public IP, sceond one for private IP (192.168.XX.XX)

two web server with one ethernet for each one connected to my private network.      

Have you got ideas or you can provide me examples?    

Thanks,    

Carlo
