Linerate UDP virtual servers.

Question is can you create a virtual server using linerate that will load balance UDP connections? I have a request from a client to set up a VIP for UDP port 5060 in support of their SIP connections. The only services I see in the configurations are http and tcp so I am assuming it is not supported. I have done some research and most of the documentation shows the following:

 

UDP

 

The system discards most UDP requests, with the exception of DNS request responses. The system accepts the following traffic:

 

MOUNT (dynamic port number) NFS (port 2049) RPCBIND (port 111) STAT (dynamic port number)

 

Aside from the RPCBIND service, these Sun RPC services have dynamically assigned port numbers which are then discovered by the client via RPCBIND. Client traffic returning on ephemeral ports will also be accepted and processed. All other traffic on ports without bound sockets in the LISTEN state is discarded without processing or ICMP generation. These services are all NFS-related. These ports will be open and active only when using the PXE boot feature in F5® LineRate®.

 

Thanks Jeremy

    Hello Jeremy. The LineRate system does not support UDP Virtual Servers, just like you noticed. It looks like you found the information about UDP in our docs, but here's the link to it just in case:

     

    https://docs.lineratesystems.com/093Release_2.5.2/100Getting_Started_Guide/100LineRate_OverviewUDP

     

    It is possible to pass UDP traffic through the device, too, but this behavior is more like a router rather than a load balancer:

      Hi Andrew, Thank you for verifying what i thought.. I will be looking into other resources for my clients request. I would hope F5 offers a virtual LB product that would support UDP virtual servers just need to research what that may be. Thanks again for taking the time to answer my question. Jeremy

      Not a problem, Jeremy. Depending on what you are trying to do, BIG-IP LTM may be a useful solution for you.
