I never used to have this problem before, and I'm not entirely sure what caused it... it might've been the fact that my internal IP switched when I put up a password on our router, but I seem to have everything set up accordingly...

The deal is, is that I host a private gaming server from my computer. I edit the hosts file in my [Windows --> system32 --> drivers --> etc] folder, and add this to the file:

127.0.0.1 logon-tcs.dyndns.org
<<Internal IP>> logon-tcs.dyndns.org
<<External IP>> logon-tcs.dyndns.org

Then I route the hostname to my external ip via dyndns.com.

With these done, others should be able to ping my external IP, which is 71.201.242.190. The users I regularly have aren't able to connect to my game server anymore, because they're unable to ping my external IP, or the hostname I have them use (which is routed to my external IP).

I've had them try pinging the hostname, and the external IP itself, but to no avail.


If anyone knows of any possible solution, please share.

Thanks!

do you have a fixed IP from the ISP
check your IP here http://www.whatsmyip.org/ - most ISP assign a different ISP each time you log into the service

Well this is what's going on now:




Is that permitted by your ISP? If not, your ISP may have simply decided to block that usage instead of terminating your service.



For example, Comcast Acceptable Use Policy for Residential service includes this Technical restriction:


I hate to believe it, but this may be the case... It just seems really random that it would happen all of a sudden without any warning.



I'm wondering if there's anything I can do inside the router settings in order to bypass this. I don't exactly know how Comcast was able to do this (if this is in fact the case).

First, as Terry net said check your external IP. www.whatismyip.com and make sure that is the IP you have registered on the dydns systems. Second, when hosting a game server they every often connect on a different port than the standard open ports, plus you are natting This means one of three things,
1) You local computer has a different IP address than before. If that is the case than the port forwarding you have on your router is not pointed correctly any more. You need port forwarding when you nat.
2)the port is now closed on the router, or on you local computer. Check you firewalls (both router and computer)
3) your ISP has blocked the traffic.

I have listed these in order of what I think they are.


I have verified that my external IP is the same and has not changed.
I have forwarded every single port necessary to forward when hosting the server.
I checked both firewalls.

I'm using a Linksys Wireless-N Broadband Router WRT160Nv3. We had to purchase a modem because this router isn't a combo.

I never changed any configurations with the router besides the port forwarding, so I have no clue where I would be able to change whether or not the router can reply to pings.





Basically, I think it could be Comcast blocking the connection, but I'm not entirely sure.

I changed my internal IP from 103 to 102, and I'm still waiting on my friend to see if they can connect with everything reconfigured to that internal IP.

And, in order for users to connect to my server which is being hosted from my external IP (which is routed to a hostname), they'd have to be able to establish a connection (ping) my IP.




I'm just a little lost on what to try next =P

I will check with my professor next week to see if I can come up with a solution or an answer as to what Comcast may be doing to block the server. There are allot of changes most ISP are going through because of the new laws governing Peer to Peer file sharing. Some have implemented and are now enforcing strict guidelines on how their Public IP addresses are shared and licensed. Your TOS (Terms Of Service Agreement) strictly forbids you from operating the Game server I am afraid we are unable to continue and would not be able to provide the information to bypass any restriction they have in place.

I will check with a Moderator if this topic needs to be addressed. If the topic is in violation of forum rules and I have not misread your TOS the topic will be closed.Otherwise it will be remain open for further discussion.

Just to point out, that you are not support to edit the hosts file to reflect Domain Name Information that is a huge mistake. The hosts file is only for local area networks only and does not perform any other functions.

Can you do another http://www.whatismyip.com and post the results here. Ping can be disabled on your router, and is no indication that traffic or your activity is being blocked.

Check your router settings and remove your hosts entries as they should not be there and see if you have issues. You are blocking ICMP not Comcast.
