Hosting doesn’t carry a great overhead, if your machine spec is OK - which yours appears to be - and you normally run Il2 without problems you should be able to host. More important is your connection bandwidth. You need to know the upload figure, and that is not always quoted. 256kbps up is standard on ADSL. Go to PC_Pitstop and test your connection. Opinions vary but I allow 12kbps per player - so a 256 upload should be OK for 10v10 coop missions.
Your timeouts may well be your router. You will need to open a port on 21000, my router interface calls this a “virtual server” but terminology differs. Take a look at your router manual, or get one of our resident experts on TS.
Personally, I would consider ditching Norton. It’s a great security product, but sheesh does it think it owns the place. It is very resource greedy. Avast! antivirus will do just as good a job, use half the system resource, and the home edition is free. XP Firewall and the router will handle the security side. If you stay with Norton, make sure you turn live updates off, they will screw things a treat if they kick off during a mission.
Babies? That’s a question about sex, isn’t it? Sorry, I am married, I can’t remember anything about it.
