ICMP error messages sent via router (running netfilter and doing translation) however contain unmodified "IP Header + First 8 Bytes of Original Datagram's Data" of packets sent in internal network (i.e. IP addresses inside ICMP error messages aren't translated). Is this expected behavior of netfilter? Is it possible to translate IP addresses inside ICMP messages using netfilter? ^ permalink raw reply [flat|nested] 2+ messages in thread
