Craig,
Could you be more specific with your setup for blocking specific IP addresses in the /etc/rc.d/init.d/masq file?
I'm running transproxy, so I don't know if that makes a difference here. I'm hoping that transproxy will catch and force ALL Internet bound traffic to run through my SME server so that I can control it.
I may end up installing squidguard or Dan's Guardian, but I really only want to block a few unruly users from certain sites, so I may not need those programs for this.
Any ideas/tips/thoughts would be appreaciated, thanks.
Patrick
