to modify the destination of locally-generated packets--you need to
modify the OUTPUT chain of the NAT table. also--your kernel needs to be
compiled with:
CONFIG_IP_NF_NAT_LOCAL=y
and don't try and use 127.0.0.1--use:
iptables -t nat -I OUTPUT -p tcp -d 192.168.0.8 --dport 25 \
-j DNAT --to-destination 192.168.0.8:2525
-j
