IPtables web interface?? / Life with a dynamic ip...

I ssh to my works' webservers. However, I have a dynamic ip at home and
have to constantly add my new ip address to the iptables. Is there a
easy way around this, or is there some sort of backend webscript out
there for adding ip via a web interface? Any direction or help is
appriciated.

Thanks in advance,

Josh

Get yourself an account with a dynamic IP/hostname service for your home
account (eg dyndns) [www.myhomecomputer.dyndns.org] and set up your home
system so it updates the service when the IP is changed

On the work computer run a cron job every 10 minutes to check the IP for
www.myhomecomputer.dyndns.org . If it has changed re-run iptables with the
new IP address.

Do you know if there's a sample script out there that would do this?

Robert L. Ziegler, in Linux Firewalls, 2nd ed., p.178, mentions that...

"One of the configuration parameters that you can specify in
/etc/pump.conf is the path and name of an executable script that pump
will run when it recieves an IP address and again at each lease
renewal."

One could imagine an executable script that contains the iptables -R
command for changing iptables every time the DHCP server issued a
lease, although I'm not familiar with the global variables needed.

There are several. Just go to the dyndns.org website
and follow the links for dyndns client.

There are several dynamic dns providers. Just Google
for 'dynamic dns' and pick your favourite (mine is dyndns.org).

I'm looking for a script that would update iptables when the ip of the
dyndns account changes.

Did you follow the links at
<http://www.dyndns.org/services/dyndns/clients.html>?

Many of the clients are scripts.

Google for 'dyndns client script' gave about 45000 hits.
Go see.
