https://community.hpe.com/t5/operating-system-hp-ux/ipfilter-rules/m-p/3088957#M144343 HI All,<BR /><BR />I have installed the HP's IPfilter on 11i. This is my DNS server. I like to open some tcp/udp ports, rest will be closed. <BR />Whatever, for test, when I put a rule that only deny all icmp packet in /etc/opt/ipf/ipf.conf file, it deny all other packets too, like dns querries, telnet, ssh, ftp.<BR /><BR />Why it is happening?<BR />Thanks a lot,<BR /><BR />Richard Wed, 08 Oct 2003 23:40:37 GMT Rgomes 2003-10-08T23:40:37Z https://community.hpe.com/t5/operating-system-hp-ux/ipfilter-rules/m-p/3088957#M144343 HI All,<BR /><BR />I have installed the HP's IPfilter on 11i.
