So... why am I being pinged evey 5 seconds by this address?
To keep udp port mapping open (so you can establish direct connection even the computer is befinde nat), Gbridge need to send out a udp package every so often. Our solution is to send out a tiny udp package, which doesn't include any information about your computer, to our server, with short ip ttl. The ttl is so short that it will exprie on its way and never reach our server. The router that drop the ttl-exprired udp packet will send back an ICMP time-to-live-exceeded message, which likely is what you saw, not this is not a normal ICMP request, i.e. ping, message. Can you analyse your network trace to verify what I said? Thanks!
