Using ip protocol 250 in fw rules

Hi,
How I can use ip protocol 250 in fw rules.
I have software which connents to server 
via ip protocol 250.
I want to place fw between client and server.

  • Hello,
    See below iptables log:

    27 07:30:09 fw1 kernel: RULE 15 -- ACCEPT IN=eth1 OUT=eth0 SRC=xxx.xxx.xxx.xxx DST=xxx.xxx.xxx.xxx LEN=84 TOS=0x00 PREC=0x00 TTL=117 ID=97 PROTO=250

    PROTO=250 is protocol which we have to insert
    into astaro's fw rules

    Thanks in advance
  • hooray, someone found the scotty protocol and described it
    in the ip protocol 250 - how to beam through IP     

    But maybe I am just stupid or have something overseen.
    Could you please clarify what protocol 250 should be? 
    It appears as unassigned in RFC 1700.

    read you

  • Hello,
    I want to ask differently:
    In iptables rule I can simply write:
    IPTABLES -A OUTPUT -p 250 *************
    and this rule will accept only the packets that
    have PROTO=250 in packet header.

    See bellow tcpdump log for that packets.

    10:36:25.380181 xxx.xxx.xxx.xxx > xxx.xxx.xxx.xxx:  ip-proto-250 56 (DF)
    10:36:25.387587 xxx.xxx.xxx.xxx > xxx.xxx.xxx.xxx:  ip-proto-250 70
    10:36:25.395986 xxx.xxx.xxx.xxx > xxx.xxx.xxx.xxx:  ip-proto-250 70
    10:36:25.396263 xxx.xxx.xxx.xxx > xxx.xxx.xxx.xxx:  ip-proto-250 56 (DF)

    I just need to know can I perform the same filtering using Astaro Firewall or not.
