What about port 2048 for GRE(47) packaged in ip protocol
...54 IP 192.168.0.31 > 192.168.0.124: ICMP 192.168.0.31 protocol 47 port 2048 unreachable, length 116 ? ? ? ? ?The 1st and 3rd lines is easy to understand, but what about ?the 2nd and 4th lines??? Is the raw package been sent up into gre protocol while caught by my program?? ? ? ? ? ?I have seen ICMP_PORT_UNREACH ?stuff been placed in ip_gre.c kernel code, but say it is "Impossible event". So, what's wrong, ?have I missed something in my program? Any suggestions are appreciated, thanks. ?
