I ve a question about the procedure for changing the Public IP
address/subnetmask of VPN slave.

Can someone give me the right info about how to do this? (TID?)

Slave Information:
Bordermanager 3.8 SP3
Netware 6 SP5

Master Information
Bordermanager 3.8
2 slaves

Sometime ago (year) we did the same for a Master server and it was only a
way of changing the Public IP settings in imanager and the changing the
filters. After that all was working fine again.

I want to know for sure if this is the same for a VPN slave server.
