Firewall configuration and monitoring.

2015-10-09: City Linux can configure your Linux based "ipchains" firewall and your router firewall to ensure you have the best protection possible. In addition for a small monthly fee I can remotely monitor the state of the firewall and trigger alerts should any thing change unexpectedly.

City Linux can retain a secure copy of your firewall configuration and even restore the desired configuration automatically while we work out the who and the why of any unauthorised changes.
