Is Orcon running a Transparent Proxy server (or perhaps even a net filter)?

Since the 7th of January (Thursday), I'm having problems logging onto a MMO hosted in Sweden. I've asked around - seems like I'm the only person who can't log-in (connection times out).

Nothing wrong on my end - even tried launching the MMO in a freshly made VM. Same result.

60.234.9.2xx often gets mysteriously in contact, with the TIME_WAIT stamp retrieved by netstat.

My hunch: Either Orcon is blocking something that they shouldn't be, or the company that hosts the MMO servers are blocking IP adresses/IP ranges they shouldn't.

Everything worked 100% until the 7th; no recent MMO updates.
