I get that message sometimes myself. In my case it has to do with my insane firewall. Between the NATd and the Internal Network, all proto and port ranges are passed/allowed. While, between the NATd and the External Network (internet) very few outbound and even fewer inbound port(s) are allowed. If I drop all my firewall rules and just do diverting and passing of all traffic between all interfaces the error goes away; However, do too my paranoid nature I'll be living with that error instead (*^_^*) Paul Miseiko /\/ esoteric@EFNet /\/ http://teardrop.ca On Fri, 23 Nov 2001, Peter Ross wrote: > Hi, > > last month I installed a working (AFAIK;-) firewall using FreeBSD 4.4, ipfw > and natd. > > Sometimes I get a message: > > > Nov 22 17:31:25 tor natd[456]: failed to write packet back (Permission > > denied) > > Nov 22 17:31:58 tor last message repeated 6 times > > There are approximately 30 packets per day causing this message. > > I can't find a corresponding message in the ipfw-logs. > > While my firewall continues to work, my former FreeBSD 3.x firewall stopped > in this case from time to time. > > Should I be worried?
