Apparently everytime I try to connect to mIRC. On my router it shows that there is 4 SYN Flood Attacks.

Oct/11/2007 18:02:25 SYN Flood Attack Detect Packet Dropped
Oct/11/2007 18:02:22 SYN Flood Attack Detect Packet Dropped
Oct/11/2007 18:02:19 SYN Flood Attack Detect Packet Dropped
Oct/11/2007 18:02:16 SYN Flood Attack Detect Packet Dropped

How can this be stopped?

It's probably the IRC server scanning for open proxies on commonly used ports when you connect. There is usually a warning message to this effect from the server. Most all networks do this.

It is being stopped .. by your router. That's a good thing.

Well of course it's possible. Which IRC network are you connecting to when this happens? Does your router log any other information like the port(s) and IP addresses?

~ Edit ~

If this happens everytime you connect to a certain IRC network, then really you should talk an admin on that network and ask what's up. You can probably find out the name of an official channel by joining #Help (that itself may be an official network channel) and asking. I'm still curious about the server address and port(s) that you're using to connect so I can try and see if I get the same thing.

Whenever I connect to irc.rizon.net

Every port I try to connect with, it logs the SYN Flood Detection on the router.

On connection to rizon I got around 70 connection attempts (pasted below) .. it's the rizon server scanning for open proxies when you connect. Your router is doing its job and blocking the connections.
