Hello, I wonder if someone could use the TPROXY with Shorewall and transparent Squid  with using the routing rules on shorewall (tcrules) for hosts / networks (LAN) with multiples providers (WANs) directly from the internal network on port 80 (with TPROXY transparent squid or REDIRECT). On this issue, the routing rules is no...

My TCP clients connect to box A. I need to forward those connections to a server on box B, such that the original client IPs are visible to the server on B. Each box has two Ethernet ports. One port on each box is connected to WAN, and they are cross-connected in a LAN via remaining ports: ------------------- ------------------- WAN -- |eth0 Box A eth1|---LAN---|eth1 Box

Guys All the recent discussions recently, and the knowledge of a 2.6 port, of WRR has made me very keen on trying it. I had a look at the docs and examples know but my mind is not in a very receptive state. Take this simple example. Incoming internet connection of 1mbps. Shared between up to 25 users simultaneously. I know that WRR can fairly distribute the traffic amongst the currently

Hi all, I have a hard trouble with my iptables rules. I need to create a netfilter config so that it does not redirect connections from a daemon (like for example a squid proxy) to the original destinations. Searching info about that, some ways to do that include to limit the redirection rules to the incoming traffic interface, another to limit it to a certain range of source IPs or to

Sir, Kindly excuse me. I am a newbie to LARTC.. I am a small ISP in rural India distributing 1 MB link to 200 people. I have been using rshaper by Alessandro Rubini for shaping. http://freshmeat.net/projects/rshaper/ My kernel is Linux version 2.4.22-1.2115.nptl( Fedora Core 1) Rshaper is very good in controlling incoming bandwidth (from LAN) I use Squid also on this Linux Box.. Right

Hello all, I''m reading the nice documentation about shorewall with multi isp. And I wonder about squid (non transparent) and shorewall Can I use on same machine, squid with ldap ident, dansguardian, and shorewall with multi-isp (four or five) ? Perhaps there is a problem because squid mask source IP, shorewall can maintain and load balance sessions for the same source IP ? Thanks Fred

Hi, I was reading document http://shorewall.net/MultiISP.html#idp3634200. Inspired by the document I was trying to establish the following changes: * one additional interface: COMA_IF * COM[A,B,C]_IF interfaces request IP address via DHCP * all non-RFC 1918 destined trafic is NATed from INT_IF to COMA_IF * all non-RFC 1918 destined trafic from GW is routed via COMB_IF by default * non-RFC 1918
