Prioritizing the VPN packets when compared to other traffic, or
prioritize traffic inside the tunnel?

Anyway, i have a feeling that both can be achieved with other means. In
order to prioritize the tunnel itself versus other traffic, this is what
i do:

# iptables -L -n -v -t mangle | grep 5000
    0     0 TOS        udp  --  *      *       0.0.0.0/0
0.0.0.0/0           udp spt:5000 TOS set 0x10

Or in other words:

-A PREROUTING -t mangle -p udp -m udp --sport 5000 -j TOS --set-tos 0x10

Probably something similar can be applied inside the tunnel, but i never
tried that. If you do, please post the results.
