Qos & IPSec VPN

[fantom]

Hi, Was having issues with IPSec VPN client not working (I do not know if it worked before, because I used different VPN client until recently) and tracked it down to the QoS feature. If QoS is disabled, I have no issues with the IPSec VPN client and if QoS is enabled, then the VPN client cannot establish a connection.
Anyone has any insight into this? Thanks in advance.

Update: I have noticed that QoS is only an issue when establishing an IPSec connection. Once it is up, I can enable QoS back and everything works until the connection drops.

Bump. Hoping that someone might have a suggestion or two. It is annoying to have to disable/enable QoS every time I need IPSec VPN. Any hints would be appreciated.
