 Hi,
 
 IP Address 212.59.27.254 is local for your system.
 In 6.0-RELEASE you should add IPFIREWALL_FORWARD_EXTENDED
 kernel option in your kernel config.
 
 http://www.freebsd.org/releases/6.0R/relnotes-i386.html
 
 "The ipfw(8) ipfw fwd rule now supports the full packet destination 
 manipulation when the kernel option options 
 IPFIREWALL_FORWARD_EXTENDED is specified in addition to options 
 IPFIRWALL_FORWARD. This kernel option disables all restrictions to 
 ensure proper behavior for locally generated packets and allows 
 redirection of packets destined to locally configured IP addresses. 
 Note that ipfw(8) rules have to be carefully crafted to make sure that 
 things like PMTU discovery do not break."
