Open Firewall wall - no filtering rules
- Suggestion:
- Drop policy on INPUT and Forward chains
- Accept policy on OUTPUT chains
- Add accept rule to FORWARD chain to allow "ESTABLISHED" and "RELATED" packets
- Suggestion:
/sbin/iptables -I FORWARD -m state --state RELATED,ESTABLISHED -j ACCEPT
smbd and nmbd services
- Do you really want to have these on?
