I'm not certain what you are trying to achieve but point-to-point links would normally be /32, not /24. >now, from one side if I ping the other side (say 2.2.2.33/24) >everything seems ok. but if I ping any other IP in the network (say >2.2.2.100/24) the other endpoint sends back packet + an ICMP REDIRECT >packet. 2.2.2.100 is not a valid address in the network you have described. Where did you expect you expect the packet to be sent? >my sysctl output: >... > >net.inet.ip.redirect: 1 >net.inet.icmp.drop_redirect: 0 >... You don't say what you are trying to achieve but my crystal ball says that you want net.inet.ip.forwarding=1 on the remote system. -- Peter Jeremy
