Hi All I solved the problem with the ICMP Redirect in the Source file an recompiled the Kernel. All works fine now. I think, it would be a possibility to put this option into the FreeBSD Sources, or as an option in the sysctl? ICMP Redirect is a simple way to relieve a *BSD Router. Why we put al

Good Morning Crist Ok, this with the Network-IP aliases, you are right, tnx for the tip. I think you are intrested in the Flags, D for dynamic redirect and M for modified dynamical from redirect. On the BSDClient, there are no entries in the routing table with the D or M Flag. I detected two "mi
