Hi, I have 3 FreeBSD 10.2-RELEASE machines and all of them suffers of the following problem. They are not responding to ARP requests which causes network problem for me, other hosts can't access my FBSD machines on the LAN nor my FBSD hosts can see each other unless I add permanent arp entry. [root@fbsd10 /]# arping my.host.hu ARPING x.x.x.x Timeout Timeout Timeout Pinging a linux host is ok from my bsd host: [root@cool /]# arping linux.host.hu ARPING y.y.y.y 60 bytes from 00:15:17:ae:0c:44 (y.y.y.y): index=0 time=189.143 usec 60 bytes from 00:15:17:ae:0c:44 (y.y.y.y): index=1 time=335.541 usec 60 bytes from 00:15:17:ae:0c:44 (y.y.y.y): index=2 time=200.227 usec ^C I use ipfw but "ipfw -q -f flush" didn't solve the issue. Here are my sysctl.conf: security.bsd.see_other_uids=0 net.inet.tcp.recvspace=512000 net.route.netisr_maxqlen=2048 kern.ipc.nmbclusters=1310720 net.inet.tcp.sendbuf_max=16777216 net.inet.tcp.recvbuf_max=16777216 kern.ipc.soacceptqueue=32768 vm.v_free_min=19170 /boot/loader.conf: ipfw_load="YES" net.inet.ip.fw.default_to_accept=1 kern.maxusers=4096 accf_data_load="YES" hw.em.rxd=4096 any idea how to enable arp response? Thanks guys! Cheers, Csaba
