Subject:   Natd stops working on Firewall 
Message-ID:  <PAEEIJCHPFHEDADDGJFLEEHJDNAA.scotrn@cox.net>

Hi; 

Just setup my FreeBSD 4.7 Firewall using the docs 
outlined in the handbook. The install went on and 
everything seems to be working fine then boom. 
The system seems to stop routing traffic. No 
messages in the security log or natd log as to why. 

I made sure it was logging by nmaping my box from the 
outside. I even ran natd in the foreground and it still didn't 
tell me what was going on. 

There is nothing in any logfile that tells me why this thing 
just stops working so I'm thinking it may not be a daemon but
something in the kernel. 

I cannot ping the interface from the internal network but tcpdump shows 
the packets being received. (Hub network firewall_type=SIMPLE ).
 
If I logon to the console the cable modem connection is still functioning 
and I can surf from the firewall. 

Any ideas on where to look next ?? 


Cable modem using dhcp -> 192.168 home network on 
PPro w/280 MB ram. 
Intel Pro 10/100b/100+ Ethernet This card is a PCI card with 2 interfaces. 
Standard Xuser install + Kernel sources.
