Do NOT turn off your firewall trying to resolve bugs like this.
(It's utterly pointless and leaves your machine vulnerable to hackers)
It's more likely that it's the routers firewall.
- Some routers have a inbuilt firewall, make sure it's not set to any stealth mode.
- Port forwarding from your router to your pc.(Mass Effect 3 uses
UDP, so forward ports "
5659" and "
6000" to your PC.)
(See your router instructions of google them for a guide)
If you already have a firewall program in use and you are not using the internal in Windows Vista/7.
Make sure the Windows one is turned off.
(So you don't have two firewall programs on at the same time, also two firewall programs on your PC doesn't make it any safer. So it's pointless to have two active firewalls on your PC. Just don't shut off the router firewall!)
---- If neither one of this fixes this might be the problem.NAT stands for
Network Address Translation.Basically it allows more than one host on a local network to share a single IP address.
You'll have to checkup with your ISP to see if you have multiple IP addresses available...
You can ask parents/other device owners if they can disconnect their device from the web while it's disabled. This will allow you to host games and people join, assuming you have done the port forwarding.
If you don't have multiple ip addresses available. You are going to have to re-enable it for other devices to connect through the same router.
IF you have only ONE pc what you use to play ME3 in your lan. Portforwarding & firewall off stealthmode should be enough to fix this. Remember to reboot after doing the portforwarding.
(NAT assigns the same IP to all computers in LAN and uses the protocols in it to determine what packet goes to who. NAT needs port forwarding. The way around it is to disable NAT on your router, meaning instead of distributing the net... it will work as a bridge only forwarding traffic and assigning all computers a individual IP. Before disableing NAT, make sure ALL computers who will be connected have a uptodate firewall.)
