I remember two peculiarities.
Between Amsterdam and London packets were summersolting. The fifth packet arrived
before the second. Making VoIP impossible.
In the Cyberbunker every IPv4 address gave a different traceroute. Most addresses
did not work at all.
When I replaced a GrandStream ATA-486 as VoIP gateway and DSL-router by a slow
linux box, that mess cleared. Everything working fine and fast. The ICMP in
the GrandStream was broken. I guess in the Cyberbunker a local router was broken
too. The sh** needed both routers to reach the fan.
