This is a guide on how to redirect outgoing traffic from
ipaddress2. Without any further commands, this rule will not persist after a reboot. This was necessary when Purdue's firewall seemed to be blocking Google's
220.127.116.11 DNS server, and Adélie Linux's live CD could not be remounted read-write, so I needed to redirect
18.104.22.168 traffic to
22.214.171.124 on the host machine.
# sysctl net.ipv4.ip_forward=1 # iptables -t nat -A OUTPUT -d <ipaddress1> -j DNAT --to-destination <ipaddress2>1
