DNAT or NAT - QUESTION
Hi, I have a simple question. I have my firewall with 2 external Ip and 1
lan.
For example
ISP1
FW LAN----Mail Server
ISP2
Ok, when i DANT the smpt port to my mail server, I can see that the
conection in my mail server comes from the external IP of my ISP.
I need to change this so the conection to my mail server cames from the LAN
IP from my firewall
Is this possible?

please help diagnosing "ip_conntrack: table full, dropping packet"
Hi,
I run a small system with an older version of shorewall (1.4.2). It has been extremely solid for a long time.
But recently I have noticed the connection table filling up, which has never happened before. My guess is that the box is getting hit with floods.
The system only has 64M of ram and the conntrack_max is set to 4096 based on the ram. I have temporarily increased it to 8192 so that it
