The crash is actually caused by the Connect extension, which SMAC optionally uses to protect against an engine exploit.

If people followed instructions, they wouldn't have an issue.

I haven't searched he thread much, but I am either getting port scans/DoS attacks. Only occurs when my specific TF2 ports are open and my server is online.

Any way to get easy protection.

Not much knowledge in server/Internet attacks.

u need to contact ur provider to get an external firewall (or where u hosting the server?). this service is not cheap. but you should ask for that. still need to say: still not clever to use windows.

windows is still designed to use behind another firewall... im windows admin in real life since many many years. still asking me why provider still using windows for gameservers without a good firewall. except some good things within the active directory windows is always the worse solution.... for gaming neva take windows except u have much money...

its very important to record the traffic locally. forward this to ur provider and ask to block. thats same like a firewall just slower and not all provider will help. xDDDDDDDDDDDDDDD

The following commented stuff in this, if they're enabled, you can't connect to your ftp server if it's hosted on the same machine.

Code:
#$IPT -A INPUT -p tcp --syn -j DROP
#$IPT -A INPUT -m conntrack --ctstate NEW -p tcp --tcp-flags SYN,RST,ACK,FIN,URG,PSH SYN -j DROP
#$IPT -A INPUT -m conntrack --ctstate NEW -p tcp --tcp-flags SYN,RST,ACK,FIN,URG,PSH FIN -j DROP
#$IPT -A INPUT -m conntrack --ctstate NEW -p tcp --tcp-flags SYN,RST,ACK,FIN,URG,PSH ACK -j DROP
#$IPT -A INPUT -m conntrack --ctstate INVALID -p tcp ! --tcp-flags SYN,RST,ACK,FIN,URG,PSH SYN,RST,ACK,FIN,URG,PSH -j DROP
#$IPT -A INPUT -m conntrack --ctstate NEW -p tcp --tcp-flags SYN,RST,ACK,FIN,URG,PSH FIN,URG,PSH -j DROP
#$IPT -A INPUT -p UDP -f -j DROP
#$IPT -A INPUT -p TCP --syn -m iplimit --iplimit-above 9 -j DROP
#$IPT -A INPUT -m pkttype --pkt-type broadcast -j DROP
#$IPT -A INPUT -p ICMP --icmp-type echo-request -m pkttype --pkttype broadcast -j DROP
$IPT -A INPUT -p ICMP --icmp-type echo-request -m limit --limit 3/s -j ACCEPT
#$IPT -A INPUT -p TCP --syn -m iplimit --iplimit-above 3 -j DROP
#$IPT -A INPUT -p UDP -m pkttype --pkt-type broadcast -j DROP
$IPT -A INPUT -p UDP -m limit --limit 3/s -j ACCEPT
#$IPT -A INPUT -p ICMP -f -j DROP
Maybe I setup something wrong though.

@chewgum first of all you would have to do iptables -L and post your full list so we would be able to tell you if any rules were causeing you FTP server not to be connected to on the local network. If you are trying localhost and it is not working then i am guessing you are droping all local connections or you do not have the ftp server configured correctly.

These thread may help you lock down your linux install tho.

As given above. http://forums.alliedmods.net/showthread.php?t=151551

Just stuff you should be doing. https://forums.alliedmods.net/showthread.php?t=166037

And the firewall commands // how to https://forums.alliedmods.net/showthread.php?t=165560
