GRE with Qos

Hi Everyone,

I've got a problem, maybe someone can help me.

Here's teh description:

1 client, 2 sites, both sites have a PIX between the lan and the outside, a 2600 series router handles the serial line both sites (internet connections).

On each site there's only 1 IP address from the provider, so between the PIXes and routers we are using a private IP subnet.

The two PIXes are connected with an IPsec tunnel. (with isakmp)

In order to avoid NATing with the routers we have configured a GRE tunnel over the internet.

Looks like this:

LAN -> PIX -----(IPsec)----> 2600 ------(GRE)------ 2600 <---(IPSec)----PIX<----LAN

I know that it would be nice to set up a direct IPsec link between the two routers, but it's not an oprion (the client wants the IPsec built by the firewalls)

It works very nice, but they have a new request.

They want to have two traffic classes over the connection with a simple priority queueing.

We made 2 IPsec tunnels, so the routers will be able to separate the traffic to two classes, but the problem is that GRE does not support queueing as far as I know.

How can we provide QoS with this IPSec over GRE solution?

Thanks for the help,

Attila
