Hiding IP address using Speedstream modem

[Trio3b]

If this is the case, then I DO want to set my modem to "hide this address" if not for anon surfing, then for security. I have apparently had my network exposed.

This is my setup:

internet <-> 4100 modem (set to public) <-> eth0 PC1 (setup to share internet) eth1 (static 192.168.1.1) <-> 8 port hub <-> eth0 (static 192.168.1.2) PC2, eth0 (192.168.1.3) Lappy

I did it this way so I could use parental controls on PC1 to filter the network for the kids

I was just experimenting with the lappy through a spare 4100 modem direct to a separate wall jack. ( Of course I have to disconnect the phone line to the networked 4100)

I was thinking of replacing the hub with Linksys WRT54G which is supposed to be linux compatible. This way I could still use PC1 as a block (dansguardian) or shutoff the internet to the network completely by stopping squid. I would plug in the other desktops to the wired ports and use my lappy via wireless out in the workshop. Now to learn how to setup the lapptop wireless

Any thoughts appreciated.

in your setup, PC1 is acting as a router that bridges your local area network and the network that belongs to your internet service provider.

since you have a linux box setup as a getway to the internet, you can set up iptables rules and you will effectively be a small GOD that sits btw your network and the rest of the internet for your family

There are many versions = most with too little onboard memory. I use the GL model which has more memory. I have also installed third party firmware, which gives more options. Basically very little gets through the router firewall to the Firestarter firewall I use on the computer.
But the GL's should be getting cheaper as people move to routers with faster wireless connections - and I'm not seeing that yet. Best to wait... Since everything passes through one computer, a good firewall on it will do fine.

Just stumbled across this thread.  here ----> http://www.dslreports.com/forum/remark,15607820

Apparently I have an SBC "Starter Kit 4100 modem" with many  security features missing / disabled . . . . figures. So I guess the "hide IP address" option is moot?

Thanks

The number on the device label should tell you which you have

12A-4100-006 
12A-4100-506   Starter Kit model apparently

I would be inclined to put a good full featured router between my LAN and the 4100 and set the 4100 to bridge mode.
Choose a router with good traffic controls so that the traffic for a particular PC can be limited (Parental Control).
Of course if you have a dedicated PC doing the same job then there is no real difference.

Comment:
                 I think it is a disgrace that people are supplied devices that are crippled thus exposing them unnecessarily to the dangers of the 'baddies' out there.
If you now own that device maybe it is possible to update the firmware to enable the other features .....
In the meantime I guess you will just have to regard it as a modem, and ignore its private IP setting .....

Bummer!

You may want to go to the following link and see how "open" you are:

This will check which ports are open / file sharing status and lots more........

Checked at the site and all ports stealth xcept for 113 which was closed but replying. I stealthed by configuring etc/shorewall/rules. Also, except for logins and some services, I surf with cookies disabled, so between those two and setting the modem to "hide IP address" I figure I'm fairly safe for now. I may try to investigate a fimware update for the modem or just learn more about shorewall.

According to the site, stealthing 113 should not affect anything except for older servers still running IDENT and I can always "undo" if necessary.

Now on to messing with the Linksys wireless router and learning ndiswrapper for the laptop.

Thanks for the help
