VDSL modem vs. Linksys router

I recently got a new VDSL connection. The modem allows me to have 2 fixed IPs, and also can act as a wireless router but I need to pay additional $$$ to "unlock" this wireless functionality. (contrary to what I was led to believe! :roll: -- but that's another story)

So I've got 3 computers in the house - 2 wireless, 1 wired desktop. At the moment I've got my desktop plugged into 1 jack with its own fixed IP, and since I can't use my modem as a router, I'm using my old Linksys WRT54G to share the other IP.

Questions:

0) Does being directly connected to the modem with a fixed IP pose a security risk? My desktop's main operating system is OS X, and I would use Vista for gaming only occasionally. My ISP plan has some kind of "anti hacker service", but it's only free for the 1st six months. Should I renew it when it expires?

1) Will I notice significant differences (mainly in speed) if I move the desktop behind the Linksys router? It will no longer have its own fixed IP, and all 3 computers will be behind the Linksys in this scenario.

1a) Is being behind the router slightly better for security?

2) I'm most interested in sharing files, streaming videos from the desktop since it has the largest hard disk. Can I share files in the current configuration using both the modem and router? (desktop on fixed IP#1, router with 2 wireless computers behind on fixed IP#2)

Or must I have everything on the same 'network', connected to the router?
 
Just hook everything to the Linksys WRT54G and call it a day. No need to use the two IPs.

Anti-hacker service??? Are you kidding me? just dump that all together and use a firewall.
 
What you have is Modem Router combo.

It probably have one regular Dynamic DSL line and the Router part is set to authenticate and provide two local IPs.

First you have to find whether you can connect to the Modem/Router menus and configure the thingy as a regular Transparent Modem (I.e. disable the Router part).

If you can, do it and use your own Wireless Router to configure a normal working Wire/Wireless network.

P.S. I just notice that you are in Hong Kong, so take my post with a grain of salt since I am speaking out of my knowledge about USA systems.
 
I just did a very non-scientific experiment:

When plugged in directly to the modem, I streamed a HD trailer off www.apple.com/trailers and got a maximum download of 6.7MB / sec.

When plugged in to the router, I got a maximum of 4.6MB / sec.

Second strange thing I noticed is that Transmission BT always says my port is closed even though I've set up the port forwarding in the router web interface, in the same way as what I've always done. Am checking the transmission forums to see if anyone has similar issues:

I've tried ticking and unticking the "Automatically map port" box.
