Hello,

we administrate a network that has about 700 machines using a firewall
with natd. The network deals with high traffic and is configured like
this:

              Internet
                  |
                  |
                  | ISA adapter 10Mbps
              ----------
             | | PCI adapter 100Mbps
             | Firewall |------------------------Extranet
             | |
              ----------
                  | PCI adapter 100Mbps
                  |
                  |
              Intranet

The problem is that sometimes we get this error message from natd

Oct 21 16:04:49 fw natd[106]: failed to write packet back (Host is
down)

The machine also hangs up in a two times in a week basis.
Could this be caused by the traffic on the ISA adapter? Does anyone
have any hints about this problem?

Thanks in advance,
