Unable to tracert on Orange DSL

[neverender]

Hey guys,

Like many people I'm currently experiencing real problems playing World of Warcraft - ping generally appears acceptable but suffers from sporadic spikes and disconnections, making play effectively impossible. This is an issue effecting people on multiple ISPs in multiple countries, but to rule anyhting out I've been trying to diagnose my end.

However, I'm totally unable to get results from tracert. Whatever I ping, whether it be a WoW server IP or bbc.co.uk, I get a <1ms first hop to my router, followed by successive timeouts until it reaches the destination.

Surely this is not right and suggests a fairly major routing issue on Oranges end?
I've tried updating/disabling AV and Firewall software etc, to no avail.

Could just be that ICMP is low priority or blocked on those hops.

Or maybe they just block ICMP echo alltogether.
You could try a TCPTraceroute.

As a Traceroute s just an Echo ICMP packet with the TTL set to 1,2,3,4,5....n so that each hop will reach it's TTL one hop further away from the source and send TTL exceeded notices (identifying the router), there is no reason you can't do the same with TCP SYN packets.

I have only used it on linux systems, but from wikipedia:

It looks like there is a windows binary:

Worth a try, still may not work, if they block all ICMP, Type 11 which contains the 'TTL reached' control message will not get back to you, though I doubt they would do this :S.
