Hi, > What's the source of these? Are you sure they aren't being generated by > your firewall?
Some are. But I think that the firewall is generating redirects only when it sees other icmp redirects from other sources. Anyway, I would like to stop that. But how? I tried to block using PF and also tried sysctl. > Do you have multiple aliases representing logically > different subnets on the same interface? Yes. we do have this. The icmp redirects are coming in and going out through the sk0 iface. > How about the output of netstat -nr -finet and also ifconfig -a? See below. Thanks for any help.
