Hi there.
Im not much of a networking and firewalling expert, and i'm having problems understanding all those masq-stuff and filter rules. I guess i will have a few answers on this post, and i will keep posting questions here but i would like to start with two simple questions.
1. Is there anywhere in this bulletin board where i can read all about these rules and stuff that will make me understand them?
2. I have a network at home. One Astaro filrewall (4.009) with 3 NICS. One (eth1) is to my ISP (DHCP assigned IP), the second (eth2) is my DMZ and third (eth1) is my protected intranet with workstation(s).
I dont care so much for the DMZ at the moment, but i would like to know one thing... Is my (eth1) itnranet secured properly when i have these settings:
NAT/Masquerading
------------
Name: MASQ
Rule type: Masquerading
Network: Internal_Network_
Interface: UPC (UPC is my provider)
Packet filter
---------
From: Internal_Network_
To: Any
Service: Any
Action: Allow
From: Any
To: UPC_Interface_
Service: Any
Action: Allow
If not? what should i do?
I have tried using action LOG DROP on the last rule, but then ftp gets weird and stuff like that.
regards,
Henrik
