Unblock host or IP

[dingolingo]

My remote host is blocking my work address. This happened immediatly after I added the work IP to the list of available IP's in CPanel. (I was planning to send a subdomain to a server at the work address). I tried to unblock with:

iptables -D INPUT 17, but got "Index of deletion too big"

I'm running CentOS 3.1

I recently had a variation on this problem but could not resolve it. Any help would be appreciated

IPtables below. Pacific.net.au is the one being blocked. They are the service provider.

root@plato [~]# iptables -L
Chain INPUT (policy ACCEPT)

acctboth all -- anywhere anywhere

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

A good place to start would be by installing APF, it makes firewall management a LOT easier for newbies.

Once it's installed, run /etc/apf/apf to get some hints on how to use it.
