Ok. thank you for clarifying. So the external Ip would be in the OUTPUT 
chain, and I could filter more specificly there (unless I get state 
working - which would be preferable :)

It's CentOS 6 - 2.6.32-220.el6.x86_64

Is that too old?

These modules are loaded:
nf_conntrack_ipv4       9506  4
nf_defrag_ipv4          1483  1 nf_conntrack_ipv4
nf_conntrack_ipv6       8748  2
nf_defrag_ipv6         12182  1 nf_conntrack_ipv6
nf_conntrack           79453  3 nf_conntrack_ipv4,nf_conntrack_ipv6,xt_state
ipv6                  322029  38 
ip_vs,ip6t_REJECT,nf_conntrack_ipv6,nf_defrag_ipv6

Thank you for your help.
