Is there am IP for a US gateway I can ping myself? I seem to have problems pinging anything. Google.com times out on me, but I can connect to it in my browser just fine.

What error message are you seeing when you ping a domain? Also, what happens if you try pinging google public DNS, either 8.8.8.8 or 8.8.4.4?

Destination Unreachable usually indicates no route to destination, either from the source or from a router in between. Looking at the traceroute, it looks like what ever is after '10.41.0.1' is where the block may be.


Request Timed Out, usually indicates the sender didn't receive an echo reply within the alloted time, usually one second. Perhaps there's some packet filtering happening on the router...

if you disabled the win7 firewall and it's not letting anything through, some router settings block that icmp/tcp traffic. talk to your admin there to allow outbound connections from your computer.

the game client always opens connections to the server (outbound traffic), there is no inbound traffic which needs to to be forwarded. ports used on the server have a wide range.

did that vpn help? if you're on a lan with a very restrictive lan setup, i don't think they allow vpn traffic either.

lan setups that block icmp traffic are always a good indicator the admin has no clue about network security.

I got word back from my network admin.

"Typically, with some game servers, they send a return signal or ping the players network before authenticating any connection to their game server. If Path of Exile does just that, you will not be able to connect. The university blocks any kind of incoming signal to the network for security purposes. This would explain why you were able to VPN and connect to server and not connect directly through the our network itself."

So I'm basically screwed? The VPN is an option, but its super laggy. Not connecting through my university network isn't really possible because my apartment building is university owned and my ISP is the university.

As far as I'm aware, PoE doesn't require constant validation via ICMP, it's only used to ascertain the latency of the gateways on the login screen. Even if you block ICMPv4 in the firewall entirely, you should still be able to login and play. From what I've seen, post login, the majority of the communication is over TCP, so unless your University is doing some funky TCP filtering...

Out of interest, what do you have by way of outbound firewall rules of PathOfExile.exe/Client.exe?

maybe the 2 problems you got are not related:

the network thingy is just your admins having no idea about networking being "overly careful". your game client initiates the pings which should "register" your computer in their firewall and let pass return packets from the server to your computer.

the second is character models not loading. did you check your resource file with packcheck.exe? cna you lookup the game's logfile to see what is wrong?

Not necessarily. If you look at the traceroute the packets are failing after the first hop. If hop two is a University router, they could easily be blocking ICMP in and out.

the good old fear of being part of a dos attack and the lazy aproach to "fix it". he could mail them to have his computer excluded from the icmp blockage, it's worth a try.

He could, but it's highly unlikely they'll break policy, if that's what it is. Regardless, as I said earlier, ICMP being blocked, shouldn't prevent the game being played. With the capture I ran earlier, the only point at which ICMP is used is when displaying the gateways on the login screen.

i didn't comment on this because i acknowledged it. the ingame ping should work though.

his only remaining problem is the char selection not appearing. looking into the logfile should shed some light into the issue.

or mail ggg.
