Many many thanks! sysctl net.inet.flowtable.enable=0 instantly fixed the issue :) Thought I was going to have to reboot all the machines to fix there for a while, which wouldn't have been fun. Seems like the flow table is pretty broken then with respect changing arp entries, at least in 8.2-RELE

We've not enabled it specifically but we may be:- sysctl -a |grep flowtable net.inet.ip.output_flowtable_size: 32768 net.inet.flowtable.stats: net.inet.flowtable.nmbflows: 197632 net.inet.flowtable.tcp_expire: 86400 net.inet.flowtable.fin_wait_expire: 600 net.inet.flowtable.udp_expire: 300 net.

very strange arp problem after ip move - icmp works udp doesn't
