No internet-uplink in backup-node with static WAN IP

[skydiablo]

hi,
in my ha setup, i have to configure the public WAN ip as static, so i generate an CARP solution. but in case all is normal, my backup-node has no internet WAN ip and also no internet uplink. my problem is, i can not install updates or anthing else which is needed internet on backup-node?!
how can i use the master-node as internet/default uplink for the backup-node? in an automatic mode, of ourse.

thx, volker.

How does the backup node obtain its WAN IP.? This must be specified at Interfaces - >Wan.
