Date: Wed, 29 Nov 2006 23:26:51 +0800 From: Wensong Zhang <wensong@...ux-vs.org> To: Horms <horms@...ge.net.au> Cc: netdev@...r.kernel.org, David Miller <davem@...emloft.net>, Julian Anastasov <ja@....bg>, Joseph Mack NA3T <jmack@...d.net>, Jinhua Luo <home_king@....com> Subject: Re: [PATCH] [IPVS] transparent proxying Hi Horms, I see that this patch probably makes IPVS code a bit complicated and packet traversing less efficiently. If I remember correctly, policy-based routing can work with IPVS in kernel 2.2 and 2.4 for transparent cache cluster for a long time. It should work in kernel 2.6 too. For example, we can use iptables/ipchains to mark all web traffic with fwmark 1, then use policy-based routing to route all web traffic through NF_IP_LOCAL_IN, so that ip_vs_in can capture the packets and load balance packets to cache servers. ip rule add prio 100 fwmark 1 table 100 ip route add local 0/0 dev lo table 100 ipvsadm -A -f 1 -s wlc ipvsadm -a -f 1 -w 100 -r cache1 ipvsadm -a -f 1 -w 100 -r cache2 ipvsadm -a -f 1 -w 100 -r cache2 ...
