  Subject: iptables problem 


  hi.
  I am unskilled english. just understand my mail.

  my box : kernel 2.4.18, iptables 1.2.5

  i am serching ip_masq_h323 for kernel 2.4.18 but it is too hard to find.

  because, in my NAT, I want to use VoIP(Voice over IP).

  How to get h323 module or source for iptables 1.2.5 or later?
