Latency on Site-to-Site VPN

[ercangunes]

Hi,

I am using a  pfsense 2.0 RC3 Firewall on our HQ and also in our Branches old version of pfsense.  I already set-up site-to-site vpn between  hq and Braches.  There is a latency between  HQ an  Breaches we the client try to connect from Brach to HQ with RDP or similar protocols.

When I try to connect using PPTP client from Brach to Head Quarter,  Client doesnt have an latency with RDP or other protocols.  When I start the debug with ssh , I just see an warrning message  2011-08-02 22:39:48: [x.x.x.xx ERROR: unknown Informational exchange received.

Is there a advise on it ?

Regards,
