    Hello,
    I got this message kernel: nf_ct_ras: decoding error: out of range today.

    That's just a warning. It means the Netfilter ct_ras helper module tried to process a packet thinking it was destined to him, only to find out it wasn't.

    In newer versions of the kernel they simply removed that warning as it was scaring people, you can just ignore it.

    Hi,

    Yesterday evening I go three of this messages:
    Code:
    Feb 11 23:45:20 kernel: nf_ct_ras: decoding error: out of range
    Feb 11 23:45:37 kernel: nf_ct_ras: decoding error: out of range
    Feb 11 23:45:55 kernel: nf_ct_ras: decoding error: out of range
    Running the current Beta 4, it means that the warning/information message is still (or again) there...

    With kind regards
    Joe :cool:

    The error message was never removed. By newer kernel, I mean newer than what Asuswrt uses (2.6.22.19).

    That never was "fixed". In fact it's not a bug, it's just a notice from the kernel that the H323 NAT helper received a packet that wasn't really intended for it.

    Latter versions of the Linux kernel modified the module to only output it when syslog is set to log packets with severity level of INFO.

    If you don't use any SIP or H.323 based device or software you can disable the helpers on the WAN -> NAT Passthrough page if it really bothers you.

    I saw this in the log, repeated several times in the last days:
    Do I need to ignore "out of bound" as I need to ignore "out of range"?
    Thanks.

    Yes. Any message from this netfilter helper if you don't use SIP can be ignored.
