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?
