Q. How do I filter larger number of subnets and IPs using OpenBSD’s pf firewall under FreeBSD 7.x server? How do I log all dropped packets from such ips? How do I block upto 10000 IPs or subnet without any performance penalty?

I‘m trying to get data (AXFR query) from master tinydns server to secondary DNS server using tcpclient as follows:
tcpclient -v a.ns.example.com 53 axfr-get example.com example.com example.com.tmp
But I’m getting an error which read as follows:
>axfr-get: fatal: unable to parse AXFR results: protocol error
How do I fix this problem?
