Establishing a MS VPN

Posted on 2008-11-05

I've got three users in Lima Peru connecting to a server behind a firewall in Colorado.

I have no problem connecting here in Colorado.

Depending on the hotel or the office they use in Peru, they may or may not be able to establish the connection.  I'm getting a 741 error on the client side.  I do see an attempted connection on the server but the connection fails.

I would say it is a piece of hardware or software not related to our equiment and beyond our control.

The wierd twist is that two users were at the same office, one user could connect and the other couldn't.

I did make some firewall changes about a month ago, but I don't think that is the issue.  I had removed the IPSec & Key Exchange policies from the firewall.  I restored them and it did not make a difference.  

I have always kept the PPTP service on the firewall becasue that is the standard for the MS VPN.

    They can not connect both at the same time or one always works and the other never works (from that location)?

    One always worked and the other didn't.  

    Total two worked from that one location and the other didn't, but then back at his hotel the one that wouldn't work at the client site worked fine.

    I call it ... the twilight zone.

    Firewall is a Sonicwall Pro 2040... if that matters
    Server 2003 SP2

    VPN works fine from anywhere I try it.

    I had the user have the IT guy at the location that is not working check for VPN passthrough and it is enabled.

    Wait, lets make it clear:
    1. At the hotel: client A, client B and client C all work fine?
    2. At the office: client A and client B always work, client C never works?
    All three are windows clients?

    2. At the hotelB: client C. does not work
    3. At the officeA: client A and client C work, client B never works (Client C was at the office at a different time from clients A & B)
    4. At officeB: client C never works (Client A & B were never here)

    Accepted Solution

    We never were able to resolve this.  No need to anymore.  My client hasn't gone to this location in South America
