thanks!!! sorry but just now i see your message... the problem is alive... i will look what you sugest... but this problem don't would be the switch ports??? switch arp tables??? the linux machines (clients) don't loose the arp address of my dhcp server... but the windows machines and freebsd boxes do. do ipfnat nat for icmp requests??? when two or more machines ping the same host in internet, just one receive the reply. these two problems are drive me crazy! the linux box (dhcp server) did not had these problems... i trust in freebsd... if i add more time to leases... when the time go out the problem will come back... right??? why the linux boxes (clients) work fine???? thanks Chris Dillon wrote: > > On Fri, 27 Jul 2001, Marcelo Leal wrote: > > > folks... > > sorry, but i trust in you :O) > > i have a problem, and don't know where find the answers... and that list > > is for net problems... > > my desktop freebsd give me a message: arp moved from: xxx to xxx...
