trying to simulation this feature on R2 we’ve observed the following behavior:
- when ip routing is disabled we’ve seen that R2 does not use ip redirects (icmp) it receives… even if they’re now generated by R1
- when using NAT, it is not working neither even if R1 generates redirects that surprisingly get NATed too. If we consider the first ipv4 header, why this packet get Nated? is the identification field, in the ip packet, used in overload Nat to distinguish and identify Nat sessions from the same host? in this case why does R2 consider the embedded ipv4 packet? instead of the outer one…
Further on
Something needs more clarification about operation of redirection and NAT.
