nat - Prerouting with iptables, destination port to DHCP

linux - iptables: change local source address if $ iptables -t nat -A POSTROUTING --destination 10.0.0.1/32 -j SNAT --to-source 10.0.0.160 2. Using a static route. Alternatively, instead of an iptables rule, add a static route for the destination host to the routing table, using the following syntax: $ ip route add /32 via src Quick-Tip: Linux NAT in Four Steps using iptables # /sbin/iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE # /sbin/iptables -A FORWARD -i eth0 -o eth1 -m state --state RELATED,ESTABLISHED -j ACCEPT # /sbin/iptables -A FORWARD -i eth1 -o eth0 -j ACCEPT You should now be NATing. You can test this by pinging an … networking - What is MASQUERADE in the context of iptables Note that this is not limited to the internet network masquerade/NAT can be used to route traffic from one network to an other let say 10.0.0.0/24 and 192.168.0.0/24 . Iptables masquerade rule can be replaced with SNAT rule. iptables -t nat -A POSTROUTING -o eth2 -s 10.0.0.0/24 -j MASQUERADE = iptables - source ? destination ? From where

Network Address Translation (NAT) and servers, protected by a nice iptables NAT firewall. Your entire network will appear to the outside world as a single computer. (Canny network gurus can penetrate NAT firewalls, but it isn't easy.) Source NAT (SNAT) rewrites the source addresses of all outgoing packets to the firewall address.

Step-By-Step Configuration of NAT with iptables Step-By-Step Configuration of NAT with iptables. This tutorial shows how to set up network-address-translation (NAT) on a Linux system with iptables rules so that the system can act as a gateway and provide internet access to multiple hosts on a local network using a single public IP address.
