2820 VPN Port Priority was created by thekingster
Hi there

I have a bit of an urgent issue and need some help.

I have a client with a site to site vpn conencted with 2 draytek 2820's using IPSec. I want to prioritise port 3389 down this VPN as sometimes when they send an email using Exchange over the VPN, it drops their TS session. Can someone please advise?

I basically need port 3389 to override everything, it is top of the chain as it is business critical.

Thanks

D

Have you tried enabling QoS on both 2820's and setting a service priority for port 3389 (both incoming / outgoing)?

Does QoS work through the VPN or does it only apply to the WAN connection? If it is WAN only all you can do is prioritise IPSec on UDP:500.

2900Gi/v2.5.6; 2900/v2.5.6

I was having similar problems when using Exchange and RDP, fixed by increasing the UDP flood value to 1500 in the router firewall.

Hi NJH,

QoS is possible over a VPN, we have a couple of Cisco ASA/PIX devices which are configured to prioritise VoIP over an IPSec VPN.

When reading these posts late at night, sometimes I forget that not all the featuresets are available on the DrayTeks, and focus more on the actual technical possiblities.

Yes, my answer was specific to the DrayTek implementation of QoS.

2900Gi/v2.5.6; 2900/v2.5.6
