hello, i have been trying serveral firewalls and there are few that i actually like. i really like aqnitum's firewall as it grabs an ip and allows you to quickly view it before any connection is made inbound or outbound along with its other features plus you can really customize the ruleset. i also am very interested in sygate and its ability to stealth OS and Browser info. does using more than one firewall together actually worse or better? also i use a linksys router with built in NAT, i am kinda new at some of this, but is there a way to hide my IP i get from my ISP as the router seems to only hide my internal IP(my pc/network) i know if you hide the ISP IP you are basically hiding the number it needs to communicate back and forth from the internet to my ISP to me and so forth. i know however there must be a way, cuz like i said with agnitum's firewall i can grab a persons IP before i even allow communication, but it shows at times an IP usually associcated with a router or proxy such as 192.168.. addresses so this i am wondering is there a way i can do the same and if so how?
