In general: 1. Enable ip forwarding (echo 1 > /proc/sys/net/ipv4/ip_forward) 2. Implement SNAT (or Masquerading) for your internal networks/clients in the POSTROUTING chain of the nat table. 3. Set up rules in the FORWARD chain of the filter table for your internal network/clients. 4. You can do points 1-3 easily using a tool like fwbuilder (www.fwbuilder.org) In detail would not be possible, as you do not specify what your situation is exactly. -Sietse ________________________________ From: netfilter-bounces@xxxxxxxxxxxxxxxxxxx on behalf of Kaushal Shriyan Sent: Mon 24-Jul-06 8:06 To: netfilter@xxxxxxxxxxxxxxxxxxx Subject: Internet Sharing Hi ALL I have my ISP connection for Internet through ADSL router.
