    I am currently using 2 RV042's for a gateway-to-gateway VPN connection. Does anyone know if I can use the new bandwidth management (firmware with the priority option and add a service called IPSEC (port 500 I believe) and use the WAN 1 interface?

    Will it give priority to the VPN packets to and from both RV042's?

    Nope. UDP/500 is for IKE, the key management protocol. IPSec data packets travel on top of a dedicated protocol, ESP (Encapsulating Security Payload) or a combination of ESP and AH (Authentication Header) - the latter combination is not common practice though. Both ESP and AH are protocols defined at the same level as TCP and UDP. ESP is the IP protocol number 50 and AH is IP protocol 51.

    The good news is the the bandwidth management in the RV042 allows for the specification of TCP and UDP ports as well as IP protocol. So the simpler way is to add IP protocol 50 (and possibly 51) to the service list under the bandwidth management tab. Adding UDP/500 for Ike is also a good idea.
