Dangers of turning off router firewall?

[Calneon]

After moving to my uni house and getting a connection from Virgin Media, I've noticed that upon connecting to lots of different places the connection seems to go down. For example, using uTorrent would mean you couldn't connect to any websites, while searching for game servers it would only return about 100, and rapidly opening 10 tabs in the browser would mean they won't all load.

I went into router settings and disabled the firewall, and this fixed it and the internet seems faster as a whole, but I don't know if this will make the connection less secure. Any advice?

Those problems are usually caused by either too small NAT table or overly agressive DDOS detection (often part of the firewall) - so see if there are options to tweak the Denial of Service protection in the router rather than disable the firewall entirely. Tho if your using NAT your protected partially anyway.

In the same boat. Moved house and had to swap from O2 LLU to VM. The VM router is the new Netgear DGVM280 and I have the same problem. Multiple tabs in Firefox are enough to reduce the connection to a crawl.

I've disabled the Firewall and it's running fine now too. Shame there isn't a better fix.
