tesekkurler
ip_forward olayini hallettik ancak
gateay degerini bu makinadan alan client makina
internete cikmiyor bunun nedeni nedir...
olusturulan kural :
[root@adusec root]# iptables -t nat -L -n
Chain PREROUTING (policy ACCEPT)
target prot opt source destination
Chain POSTROUTING (policy ACCEPT)
target prot opt source destination
MASQUERADE all -- 10.9.0.0/24 0.0.0.0/0
MASQUERADE all -- 192.168.0.0/24 0.0.0.0/0
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
bu sekilde ....
