Updating the BIG-IP ASM attack signatures with route domain

Hi,

I have one customer with an appliance with Route domains (version 12.1.1).

the default route domain is configured only with one VLAN for HA with no other devices in this network.

All other VLANs are linked to route domains and I need to configure Attack signature update using VLAN in route domain 1 instead of default RD.

I tried to configure Proxy with command:

modify /sys db proxy.host value ProxyIP%1
modify /sys db proxy.port value ProxyPort

In ASM logs, I can see :

Can't connect to call home.f5.com:443 (Bad hostname 'ProxyIP%1')

Is there a solution to configure Attack signature update within another RD than default one.
