I want to know why needn't to define the original IP ( Public IP ) ?
eg :
iptables -t nat -A PREROUTING -i $EXT_IF -p tcp -s 202.175.xxx.xxx --dport
80 \
-j DNAT --to-destination 192.168.xxx.xxx
Sorry, what useful about the following function ( command line ) ?
> iptables -A FORWARD -i $EXT_IF -o $INT_IF -p tcp --syn -d $SRV1 \
> --dport 80 -j ACCEPT
In additional, if I want to setup a NAT ( 192.168.101.0/24 ) with a Server
machines ( 192.168.100.1 ) behind Firewall...
So, is there more than one sample ( nat scripts ) for reference ?
Edward.
