Russia ISP guide

[basil00]

Some Russian ISPs use "Carrier-grade NATs" which means that ReQrypt can be hit-and-miss.

Here is information that someone sent to me that may be useful:

• Er-Telecom: ReQrypt is unreliable.
• Beeline: ReQrypt does not work (random port NAT).
• Ufanet: ReQrypt does not work (random port NAT).
• Obit: ReQrypt works but requires a high TTL value (of 12) to punch through the NAT
• 2COM: ReQrypt works fine
