Mail Port Foward On Iptables
i,m newbie in slack. i got problem with my iptables. my linux box running as router using squid.
iptables -A POSTROUTING -t nat -o eth0 -j MASQUERADE
when i put this line to my iptables i can browsing direct to internet without put the proxy on my browser n i also can access my isp email server. if i remove that line, i must put proxy setting on my browser & it's running but i can't access email from my isp. so my conclusion when i put that line it will forward all port to internet. i just want allow port 3128,8080,25 & 110 to forwards.
can any body help me how to solved that problem.
