Shorewall nastaveni a blokace 25

Ahoj,

Radi zde, ze si mam do iptables pridat par radku (uvadim na konci), ale jelikoz pouzivam shorewall, rad bych poprosil nekoho kdo by mi poradil co mam misto pravidel IP tables napsat do shorewallu, nize uvadim jejich priklad pro IPtables, ktery bych potreboval predelat do Shorewallu a poradit co mi vlastne tyto pravidla prinesou. Diky

Nat configuration examples We would appreciate contributions of simple examples of how to configure NATs/firewalls. Please make sure you understand what these examples do before implementing anything derived from them.

Linux iptables # Assume MTA on the gateway box, nothing from the LAN needs to contact # the world on port 25 directly.

# Log packets trying to cross the interfaces. iptables -A FORWARD -p tcp --dport 25 -j LOG

# Drop those packets iptables -A FORWARD -p tcp --dport 25 -j DROP

# Assume MTA is inside the NAT and needs to be able to talk to the # world, but not receive.

# Fill in this field IP_OF_MTA_HOST= iptables -A FORWARD -p tcp -s $IP_OF_MTA_HOST --dport 25 -j ACCEPT

# Log packets trying to cross the interfaces. iptables -A FORWARD -p tcp --dport 25 -j LOG

# Drop those packets iptables -A FORWARD -p tcp --dport 25 -j DROP
