One of the issues that CLUSTERIP needed to do is to work with locally-originated connections, i.e. every node within the cluster still has to be able to open tcp connections to anywhere. We currently catch this with connection tracking, which will assign all reply packets to such outbound connections INVALID on all but the originating node in the cluster. Yes, I know, this sounds like a very strange setup. Still it was one of the requirements for it's implementation. -- - Harald Welte <laforge@xxxxxxxxxxxxx> http://www.netfilter.org/ ============================================================================ "Fragmentation is like classful addressing -- an interesting early architectural error that shows how much experimentation was going on while IP was being designed." -- Paul Vixie
