RE: [load balancing] F5 BIGIP Force to Standby doesn't work

Happy New Year to all!

Still battling with this one....

Between the two F5 units both running 4.2PTF-10 Build95, tried to force either of them into Standby, but soon after issuing the command the Config Utility status shows the unit back into ACTIVE state.
The main unit still complains about duplicate IP addresses from the second unit.

I want to run the web sites with the LB failover so the sites with HA, and now that the outbound connections problems is solved all I need is to get over this last stumbling block.

Please advise.

Cheers,
Tony.

Tony,

Have you checked the option (I think snat automap) on
the self-ip addresses?
