What does "communication administratively prohibited" mean?

Recommended Posts

Every so often my AirVPN connection seems to become unresponsive, as it is now. If I run a traceroute, I get this:
 

$ traceroute -n netflix.com
traceroute to netflix.com (54.171.21.76), 30 hops max, 60 byte packets
 1  10.12.152.1  28.185 ms  28.199 ms  28.197 ms
 2  109.202.106.81  36.160 ms !X  36.199 ms !X  36.198 ms !X

I assume 109.202.106.81 is an AirVPN server, but why is it returning "!X"? According to the man page, this means "communication administratively prohibited", but what does that really mean?

A reverse DNS lookukp on that IP returns "promarketserv.com", which is a bit of a worry.

Any ideas what's wrong here?

Thanks

No, it isn't.
If you ping this address, it should tell you Destination Unreachable. :) Which means, at some point your connection to the server goes down, or something alters the routing table. Next hop should be the datacenter of the AirVPN server. You posted no logs or other info like the routing table contents to allow troubleshooting this, so we're in the dark.

Really? I get a PTR record back leading nowhere.

$ dig PTR in 81.106.202.109.in-addr.arpa.

Four simple things:
There's a guide to AirVPN. Before you ask questions, take 30 minutes of your time to go through it.

Amazon IPs are not dangerous here. It's the fallback DNS.
Running TOR exits is discouraged. They're subject to restrictions on the internet and harm all AirVPN users.

Furthermore, I propose that your paranoia is to be destroyed. If you overdo privacy, you'll be unique among the mass again.
