I've searched the archives of the port trigger
and iptables , I found some pages that discussed
this issue last year , and it seems the answer of
my question is "NO" , so I wonder if I can get any
update of my question on this list ?
Hmm, could you please point me to that discussion? I found the following
which actually says it could work:
Besides , I knew the autofw function of ipvsadm
can meet my requirement , but it is for kernel 2.2,
can I use ipvsadm on kernel 2.4 ?
Maybe you're mixing up some things, maybe I do not understand the true
nature of your question. autofw was a feature which could be used
together with ipmasqadm to do kind of a broken auto port forward. Yes,
you can use ipvsadm with 2.4.x kernel, check out the software part of
the LVS homepage. The autofw hack is to my knowledge not available for
iptables, but I might be wrong, as I do not track all the POM
developments of netfilter. If there is a POM patch which mimics the same
behavior as autofw did, you could be lucky with fwmarking packets and
then load balance the fwmark pools.
