Hello,

Am facing the following problem:

Have setup the R480T+ (ver. 6) as a load balance router (failover) with 2 WANs from different ISPs
The LAN port is connect to a Mikrotik RB.

On the Mikrotik RB I have setup a PPTP client to be able to support the Mikrotik remotely. (from our office)
However the PPTP client is unable to connect to our remore server.

If I try again, without the TP-LINK the PPTP client connects succesfully.

I suppose something blocks the client or the related port (1723)
However checking carefully the TP-LINK's interface I couldn't find anything similar / related.

Has anyone face something like this before? Is it related to the router?
Any ideas or help would be much apreciated

Makis
