DSL router and security
I use DSL with Slink. I previously had a static IP address. I used an IP Chains ruleset as one security level. All was well.
My ISP recently mandated a configuration change for the Cisco DSL router from " bridging" to "ppp" mode, including NAT at the router level.
The router now changes my assigned IP address to a private Class A address ( 10.0.0.2 ). I changed my networking ( eth0) settings to reflect this.
I guess I no longer need the IP Chains firewall. Is this correct ?
What security considerations/measures should I now adopt with respect to my new setup ?
My knowledge of the function of this router is rudimentary.
