My Creative router modem (8133u-c1) has no firewall, as a result I get perfect apt downloads, but http://www.pcflank.com tell me that ports are visible on it (port 80, plus several 4 figure ports) so I hesitate to use it despite having Guarddog installed. This is with just an etho connection from my laptop without any other network.
They also leave all internal ports open - so that services between computers on the home network are not disrupted. There'll usually be a DNS config and DHCP server also built-in and usually pre-configured. Internal 192.168.0. -> router -> 82.217.89. etc. all ports open all ports closed
Yes, no problem with that.
Routers always have two addresses - the internal and the external. You can ping both. Typically there is a Javascript or HTML admin interface available on 192.168.0.1 or whatever is the default IP of the router. You adjust everything there - but the firewall to close all ports on the external IP has always been on by default on every router I've ever seen.
If I connect the Netgear DG632 router firewall which is on factory settings (reset to make sure) and reboot the laptop I can browse and mail - but no apt. My system however, is "fully" protected according to pcflank, but my long awaited for - perfect laptop Deb Sarge installation becomes outdated by the minute!
