I can block all addresses from a partial Class C by saying:
[ipfwadm]
/sbin/ipfwadm -I -a deny -S XXX.XXX.XX.X/25
[ipchains]
/sbin/ipchains -I input -s XXX.XXX.XX.X/25 -j DENY
Using ipchains I can block all addresses *not* from a partial Class C by
saying:
/sbin/ipchains -I input -s ! XXX.XXX.XX.X/25 -j DENY
Can I do the same with ipfwadm? (The man page says nothing.)
I'm changing servers from a 486 running kernel 2.0.36 to a PIII
runnning kernel 2.2.16-3 and want to deny access to the old server while
I transfer home directories & mail spools to the new server.
