Big-IP HA issue accessing management UI from a routed subnet
Good evening,
First time here and I don't have lots of experience with F5 but here's my question and hope someone can help :-)
I've been asked to take over an HA pair of F5 Big-IP v11.6 (virtual edition) that is configured in Active/Standby HA. The HA works fine although I still have some things to review. For the moment, I have a weird issue I can't seem to figure out. Here's a quick overview of my config:
Each BIG-IP has its own Management IP and 6 VLANs (include HA and external). Self IP and Virtual IP is defined on all VLANs. Port Lockdown is enabled only on HA (Default) and Monitoring (allow SSH and HTTPS only) VLANs.
The issue I have is when I try to manage the units through their self IP from a routed subnet. If I just try and PING both devices with their SelfIP, only one of them respond but never both. It always seems to be the Standby one that respond. The routing tables are the same on both devices.
Don't what else to check for.
Anything special I should look for?
Thanks! Sylvain
