This is a funny story…<\/p>\n
I was working quietly at home and decided to send an email to a customer which I forgot through the day (and because at some point I totally blocked), so I’m clicking ‘send’, and ‘mail.where-i-work.org connection refused’ gets displayed… I ask Voland if he’s doing something to it, but he’s not – so I try some other stuff and then I see that almost everything except port 80 is filtered, and tcptraceroute looks like this:<\/p>\n
\r\nvasil@lyra:~$ tcptraceroute marla.ludost.net 22\r\nSelected device eth1, address 192.168.9.8, port 44833 for outgoing packets\r\nTracing the path to marla.ludost.net (194.12.255.250) on TCP port 22 (ssh), 30 hops max\r\n 1 192.168.9.1 10.166 ms 1.297 ms 1.376 ms\r\n 2 85.187.137.65 4.555 ms 3.457 ms 3.061 ms\r\n 3 85.187.137.65 2.836 ms !p 3.225 ms !p 3.770 ms !p\r\n<\/pre>\nSo what now… I called megalan (good thing that they had their phone number on their site, and port 80 was open :) ), so I explained the situation to them and the exact result from the traceroute, so the guy after while told me – ok, we can’t see a problem on our side, and now we’re deep in one client renumbering and we’re really sorry, but can’t really pay a lot of attention to you… So I understood their pain, routed my traffic through the VPN I have to marla (which runs over UDP :) ), and I kept working :) But I can’t remember seeing this kind of filter, returning port unreachable :) <\/p>\n","protected":false},"excerpt":{"rendered":"
