Traceroute does not work

I have a machine in my DMZ on which I want to be able to use traceroute command. However, all connections time out. How can I allow traceroute operations to work?

Thank you!

You have to allow the following:
ICMP type 8 (Echo) from your DMZ to the Internet (a.k.a outbound)
ICMP type 0 (Echo reply) from the Internet to your DMZ (a.k.a inbound)

This will be done by adding the rules in the firewall section of your DFL-700.

IP Conflicts

I would try a different port with a new cable. IP conflict should be noted by the PC / node. You could ping the IP in question with the -a switch to resolve DNS name. You could also run a traceroute from the command prompt to help identify what drop if failing / timing out.

Well whenever I go to play online games (World of Warcraft, Allods Online, etc.) I have extremely bad Latency. I have been told by several people now its being caused by this new router. I have no idea...

Instead of relying on peoples opinions, try testing it for yourself. Remove the router and connect directly to your pc (I assume you have a modem somwhere). Does the problem persist?

If so contact your isp (a lot of gamer probs are caused by crappy isp's, they don't like people who actually use their connections, although they seem to be getting better)

If removing the router helped then maybe think about not using it, at least when you play games, or get a better one that gamers rate well. If you connect using wireless then don't, wireless is slower than using a cable, and will definitely increase your latency too much.

A traceroute would show you where the latency creeps up. It's been too long since I last did one and it's 2.30 in the morning here so you're on your own with that one, for now anyway.

I'll try to remember to look up how to do a traceroute properly tomorow and add it to this page. the command is tracert and then an option such as -a and then an ip address ( eg game server) so it'll look something like "tracert -a" but I can't remember the other options (or what -a does in this case). Also i'll think about how to speed your router up, if it is that causing your woes.

I hope i've helped a bit, if not then maybe tomorrow

My latency is high when playing games

Network latency depends on the application you are using , while playing network games it can be high because of long distance of connectivity or long cable connections, secondly it depends on the switch or hub is using between 2 PCs or number of PCs ,
I propose a small solution to you "TraceRoute" which you can download by your own its a 30 days trial, It can analyze your network latency and performance degradation '

Stuck at finding server

You need to find out if you have a firewall or other piece of network hardware that could be interfering with your connecting to the server. One way to do this is to run the linux traceroute command or windows tracert like this:
> traceroute
> tracert

Also try pinging the remote host:
> ping

Internet speed not as indicated by modem

problem occurs usually after upgrade of internet speed. contact your ISP again, ask them to check for latency or dropped packets within their network. they need to run a traceroute from their end and it would also be better if you can run a traceroute from your end. also run a speedtest through or There's also a possibility that the modem is becoming faulty. If your ISP provided you the modem it's still best to contact them for possible replacement.
