Hello, I have a quick question is there a way to support a dynamic client IP, other than reloading shorewall every 10 minutes from cron. To be more precise, I''m travelling a lot and I wanted to have ssh and smtp access on my own server. I want to limit access to this service to my laptop at my-laptop.dyndns.org. My understanding of shorewall/iptables tells me that using the cron job solution is the only viable one ... so if you could just confirm this assumption, it would be nice.

Using dynamic IP addresses as a security measure is more trouble than it is worth. -Tom -- Tom Eastep \ Nothing is foolproof to a sufficiently talented fool Shoreline, \ http://shorewall.net Washington USA \ teastep@shorewall.net PGP Public Key \ https://lists.shorewall.net/teastep.pgp.key
