...tunnel. It is like the kernel is not delivering them. Also my gre tunnels on CentOS 6.5 are named gre1 at NONE and gre2 at NONE with an ip a s, while on the 6.4 CentOS system they show up as only gre1 and gre2? Whats with the @NONE?

...CMP 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. ?

At the time i run asterisk, even i got bindaddr=0.0.0.0, it does not show any port open for sip (5060), if i change 0.0.0.0 for any ip, next time i reload, it opens the specific ip, changing back to 0.0.0.0 and reloading, it keeps the same ip open. The point is that i cant open all ips i...
