Cannot remove old external interface. Managed BOVPN + Multi-WAN
We switched ISPs in a small remote office. I set the new connection to use port 4 in their T35-W. Old connection was on port 0. I enabled multi-wan and set the new connection as #1. Updated WSM with the new external IP and can confirm all managed BOVPN connections work fine.
Went to disable the old connection, but can't since the DVCP-created gateway has both external connections listed. Can't disable the interface in multi-wan because it needs at least two. Can't manually edit the DVCP-created gateway.
Is there a way to disable the old interface w/o removing and re-creating all the managed VPNs?
