Are there additional messages after the Segmentation fault? I suspect that iptables-restore is blowing up for some reason. In general, using large Shorewall blacklists is a very poor idea. Any connection that is accepted by the firewall must pass serially through the entire blacklist. For blocking other countries, I suggest upgrading to Shorewall 4.5.4 and using the builtin country-matching feature available in that version. For other blacklisting where a large number of address ranges are involved, ipsets are a much more efficient solution. -Tom -- Tom Eastep \ When I die, I want to go like my Grandfather who Shoreline, \ died peacefully in his sleep.
