Hey lads...

I'll give you a run down of my current setup:

I have a Motorola SBG900 wireless cable router/modem.
I have 1 PC connected to it via RJ45 cable - this is my day-to-day computer for gaming/email/banking etc. (Computer 1)
I have 1 PC connected via a Netgear WG111 Wireless USB adapter. (Computer 2)
Both access the internet without problems.

What I want to do is make Computer 2 use a Static IP Address, and enable Port Forwarding in the SBG900 (so that Computer 2can be utilised for P2P connections).

I understand that P2P connections are prone to viruses etc, so I want to ensure that I can effectively make the changes to the Router and Computer 2 without the effecting the security of Computer 1. I can't afford to get a virus on Computer 1!!!

If I disable DHCP in the Router, does this mean I will need to allocate Static IP Addresses to both Computer 1 and Computer 2? In addition to that, if I then have made a Static IP for Computer 1, and also enable Port Forwarding in the Router, will that affect the security of Computer 1 in any way?

If there is anything I have missed, or you think pertinent, please let me know!

Cheers!!

the router should have a firewall on it aswell as firewalls on both computers (just incase). With your network you will have wep/wpa/wpa2 security on and if you turn off DHCP you will need to assign static IP's to both computers.
Maybe if your router supports mac filtering do that and also turn off broadcast of your wireless. Thats should take care of network security. Any changes to your router should be done while connect wired.

with viruses Generally with p2p, everything needs to be scanned and i never get any .exe files (i think alot of viruses come this way) also before extracting anything scan it.
