I'm trying to block some particular network traffic.  The stuff in
question (from tcpdump) is:

15:16:24.311352 SEPTUM.MIT.EDU.1121 > 18.62.255.255.sunrpc: udp 96

nslookup on septum shows 18.62.4.130.

So I put a line in /etc/ipf.conf:

block in quick on ep1 from 18.62.0.0/16 to 18.62.255.255/32  port=sunrpc

but this doesn't do it.  I still see the packets with tcpdump and ipfstat
doesn't show any blocked.

What am I doing wrong?

Thanks
