Hi,

I'm trying to open ports 10000-20000 on a Juniper SSG 5.

I know how to do it for individual ports via VIP but is there a way to do more ports in one go?

Thanks

Just define a custom service using the port range. Then add that service in the VIP definition, and provide the first (!) port to map the VIP to (10000).
The according policy for that VIP will automatically allow traffic from those ports, so nothing to do there, if you already have a policy for the VIP.

I have tried that, but it hits a limit of 64 ports.

Possible. That's the way VIP works, it is not intended to have such a wide-spread port range, and unless you want to break it down to 64 ports packages, there is no way around.

You should consider using a MIP instead - if you've got more than one public IP, that is.

Or maybe you should explain why you would need to do that - there might be better options.

its due to Voice Traffic, (RTP)

I will have a play with MIP instead

Thank you.

NAT with VoIP might be an issue in itself, but using a MIP is better than a VIP for that.
