You may also wish to look at firewall rules. If return-udp packets are filtered, one may run into transfer problems with tftp, even using "stateful" udp inspection. The return udp source port will be the server's transfer identification number, and this will not often be port 69, as the filter would expect from the state table. If you have implemented filtering, you should check into this. ari rwatson@freebsd.org said this stuff: > > On Tue, 24 Feb 2004, Ganbold wrote: > > > Maybe this is off topic question.
