SNAT problem on 9.3.1
I currently have 1 pair of LTMs where my current configuration works, and one where it doesn't. Here is the setup:
1 KVM currently going to a switch with a private VLAN setup that only has 3 ports. 1 for the KVM port, and 1 port for each of the F5s. The F5s and KVM are setup within the same /24 network. This is all setup on the F5s in a VLAN called KVM. I'm trying to log into the KVM with a radius username and password that is verified on a Cisco ACS on a VLAN labeled as external on the F5.
I setup the SNAT so that the Translation is to an address on the same network as the ACS in the external VLAN which is not used by any other device. The origin is set for Address List, and that list only contains one IP address, which is the KVM address on the private KVM VLAN. It is enabled only on the KVM VLAN.
When I do a tcpdump on the external interface, I see the KVM private network address trying to go to the public ACS address. I should be seeing the SNAT address trying to reach the public ACS address.
I have this identical setup on a different LTM pair, and it works properly. It's just this set that doesn't work. I would prefer not to swap which LTM is active or standby, as if there is an issue, this device is difficult to physically access to fix any issues. Is there a log or service I might be able to check on the LTM in order to check why the SNAT isn't working?
