Gameunited port scan

[WeBeGood]

I was on the gamesunited web site, did a traceroute, now my firewall looks like gamesunited is doing a port scan

212.6.108.246:2870 to myip:33510
212.6.108.246:2870 to myip:33511
212.6.108.246:2870 to myip:33512
...

am i interpeting what's going on wrong?

change your IP.

I think you have to ask this one to the gamesunited staff, who will be not really checking this forum, since it seems to be a host for many types of games.
But I am sure they just output the call of traceroute and have nothing to do with traceroutes implementation issues except for providing the service.
Unclear why traceroute is trying so many ports, maybe your ping port is blocked by your firewall and it tries other ports. Havent looked at the implementation of any traceroute tool, guess the answer is in there.


EDIT:

snippets: traceroute.c

Code: Select all

/*
...
 * To keep track of which probe is being
 * replied to (so times and/or hop counts don't get confused by a
 * reply that was delayed in transit), we increment the destination
 * port number before each probe.
*/
int nprobes = 3;
...
for (probe = 0; probe < nprobes; ++probe) {
  ...
  send_probe(++seq, ttl);
  ...
}

send_probe(int seq, ttl)
{
  ...
  up->uh_dport = htons(port+seq);
  ...
}
