Can anyone confirm proper procedure for shared gateways, i have a CP4 running an AV program in slot 1, D3 program in slot 2, i have the ipid set to 3 and 4 in both programs. Just got off the phone with TB and they are saying they definitely need to be different with multiple ip table entries on the gateway.
Is this correct? i thought that was the case when you had shared gateways between multiple processors

The "correct" method is for each program, whether on the same processor or not,
to have a unique IP ID.

You could probably do it both ways, but one ip table works when you're using
one processor. Here's how I have a system set up on a CP3:

CEN-GWEXER: IP-ID 03 -> CP3 IP Address

CP3 Program 1(AV): IP-ID 03 CEN-GWEXER (Shared)
CP3 Program 2(D3): IP-ID 03 CEN-GWEXER (Shared)

I agree with Tony. I always have a separate IP-ID for each program that is communicating with the GW.
Thus I would do this, whether in the same of different processors:

CEN-GWEXER: I
P-ID 03 -> CP3 IP Address
P-ID 04 -> CP3 IP Address

CP3 Program 1(AV): IP-ID 03 CEN-GWEXER (Shared)
CP3 Program 2(D3): IP-ID 04 CEN-GWEXER (Shared)

Even if the alternative method works, I still wouldn't use it because:
a. I don't trust it, and it frankly *shouldn't* work without issues IMHO
b. its harder to trouble-shoot things. with 2+ IP-IDs, you know in the GWEXER's IPTable, whether each program is on-line. this has been helpful. If you have just one IP-ID, which program is Online?? one, the other or both??

It should only be done as Ckangis stated. You cannot use the same IP ID on two program slots of a processor. If you were sharing the gateway between two processors though, you could use the same ID in two entries on the gateway that point to the two processor IP addresses. But I am in the habit of making the IDs different so its consistent across all applications?

Agreed with JohnMax.? It's the old adage "Just 'cause you can...doesn't mean you should!"...:)

Also, you want to/have to manage the RF-IDs so that you don't have duplicate device IDs...It's obvious I think but its something that if you don't plan in advance, it will be a pain later to make the changes...
